The Vera C. Rubin Observatory in Chile is a new world-class astronomy facility designed to create a 10-year time-lapse map of the southern sky. Featuring the world’s largest digital camera it emits 20GB of raw pixels per minute, and we are developing the Prompt Processing System that will distribute an alert on every astrophysical object that has moved, changed or appeared in real-time. (https://rubinobservatory.org/news/first-alerts)

Keep Rubin's Alert Stream flowing. We are hiring an SRE to own the reliability of our Prompt Processing Framework, a Kubernetes-based, event-driven system using KEDA, Redis Streams, Kafka, and Postgres to scale near-real-time processing. You’ll write software to improve resilience, operate and evolve core infrastructure services, and build the monitoring, alerting, and on-call practices that keep the system robust and reliable during nightly observing operations.

Stack: Python, Kubernetes, Helm, ArgoCD, Kafka, Redis, KEDA, InfluxDB, PostgreSQL, Cassandra.

AI startup (stealth) | Co-founder / AI engineers | REMOTE

We’re building an AI system that will disrupt the SaaS market as a whole. The foundation already exists and is running.

The concept itself is not difficult for experts once it becomes public, but the architecture and timing are key. We’re moving extremely fast.

Plan:

- release an open-source core

• build a large community around it


• scale fast enough to push competitors out

  Current state is first friendly test customers onboarding in a few days. This is just 1 week old.

  We’re currently reaching out to major AI labs since they could profit a lot from this, but we don’t need them to scale aggressively.

  Right now there’s no significant funding yet, but the pace is extremely high and this could gain traction very quickly. We can likely raise ~€250k fairly quickly via public funding in my country, without giving up shares, but first we want to assemble the right people and make a plan together.

  Looking for:

  - someone with founder experience / VC contacts, or



• hardcore AI engineers like me who ship extremely fast

  We are currently EU-based, but the company can be set up wherever makes most sense for the business.
  It's huge fun to work with it.

Decise | Principal Engineer & Technical Strategist | Remote (US) | Fully Remote | Contract (1099)

Decise is a hands-on advisory and delivery firm that helps organizations unlock the full value of their technology and improve business profitability.

We work directly with executives to define what should be built, then we build it. Our work spans software engineering, data platforms, analytics, and customer-facing digital products. We often operate as fractional CIOs and CTOs, guiding both the strategic direction and the technical execution of our clients’ technology initiatives.

Our clients rely on us to turn complex business problems into working systems — not slide decks.

We are intentionally small and senior. Everyone on the team is a builder who can operate independently, solve complex problems, and deliver finished systems that people actually use.

White-glove service. Blue-collar grit.

We’re looking for a principal-level technologist who can move between engineering, architecture, and client strategy. Most of your time will be spent building systems and writing production code. The rest will involve working directly with executives to shape technical direction and ensure the work creates real business value.

Typical technologies we work with include React, Angular, Next.js, Node.js, Go, Snowflake, SQL, dbt, Domo, Streamlit, AWS, Vercel, and modern AI-assisted engineering tools. The exact stack varies by client; the ability to learn quickly and move confidently across technologies matters more than any specific tool.

Strong candidates typically have 10–15 years of experience building production systems and are comfortable operating both as hands-on engineers and as technical advisors to executives.

This is a long-term, full-time independent contractor engagement (1099). Everyone at Decise — including the founders — operates in this structure. Compensation is designed to be competitive with senior engineering roles at leading technology companies.

The fastest way to stand out is to show us something you’ve built: a production system, GitHub repository, application, or data platform you designed.

We're a serious, collaborative team working in what we refer to as a Lean/post-agile way. We're looking for someone with 10+ years of experience, ideally in both the front end and the back end.

Technology: Ruby, Rails, Event Sourcing, JavaScript, Stimulus/Turbo
Practices: Collaborative development (pairing, mobbing), TDD, end-to-end ownership, UI/UX design, user interviewing, etc.

If you'd like to learn more about how we work, I have several articles on the subject: https://github.com/aaronjensen/software-development/

Our current tech stack is simple and open to change: Laravel/PHP backend, alpinejs, mysql, and Bedrock on AWS.

You'll be successful in this role if you're a solid engineer and web developer, can read and write sql, and have some experience with tools and libraries like the ones we use--you needn't know exactly our stack.

Trunk | https://trunk.io
Tech Lead (CI & Test Data Platform) - San Francisco HQ and open to Relo
Marketing Lead (Developers) - Remote friendly
Developer Advocate - San Francisco HQ and open to Relo
Sr Platform Engineer - San Francisco HQ and open to Relo

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

*Flaky Tests: Detect and eliminate Flaky Tests.

Our tech stack:

Frontend: Typescript, React, Next.js, AWS
Backend: Typescript, Node, AWS
Data pipelines: Dagster, Python, polars
CI/CD: GitHub Actions

Unlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobs.

Herakles Defense | Munich, Germany | REMOTE| Full-time | Part-time available

Here's the problem: A small drone flies at you at 60mph / 100 km/h You have a camera, one edge processor, and must detect, classify, and track it at 30fps — against sky, trees, buildings. Starting from 100+ meters. If your pipeline drops a single frame at far range, the intercept fails. Sounds impossible? We think together we can solve this.

Now the second problem: Your guidance law needs to predict where that target will be in 0.5 seconds, compute the intercept geometry, and command the flight controller — with noisy IMU data, wind gusts, and a target that doesn't fly in straight lines. No GPS. No RF link. Just onboard compute.

We solved the guidance part in simulation. Our IBVS pipeline tracks and hits moving targets in SITL. The hardware prototype is built and ready. But the real engineering starts now.

We need:

* Computer Vision & Edge AI Engineer — YOLO on Jetson/Hailo/QRB5165. Detect, classify and track small targets at 100m+. Model pruning, TensorRT, sensor fusion. If you've pushed edge hardware to its absolute limits, this is your problem.

* GNC / Flight Systems Engineer — Image base visual servoing, proportional navigation, EKF/UKF state estimation, PX4 integration. Take what works in sim and make it survive real-world sensor noise.

* Simulation & Test Engineer — SITL/HITL, Monte Carlo campaigns, digital twins. 10,000 simulated engagements before anything leaves the ground.

* Technical Advisors — Drone warfare, GNC/aerospace, defense procurement. A few hours/month from the right person changes our trajectory.

We're a pre-seed defense startup in Munich building autonomous interceptor drones to stop FPV kamikaze drones. 2 founders. Salary + equity. No AI screening — we read every application.

FusionAuth | Senior Java Engineer, Technical Support Engineer, Account Executive , Solutions Engineer | Varies between REMOTE (in USA, also in Europe but only for the account exec/solutions engineer positions) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges listed on job req, but for the Senior Java Engineer it is 140k-180k

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome. We also recently acquired a fine-grained authorization company ( https://fusionauth.io/blog/fusionauth-acquires-permify ) and are going to be building in that area as well.

There are a lot of companies in the auth space, but we feel like we have something special:

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* our CTO is the founder and still writes code

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration already

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Innolitics | Medical Device Engineers + Physician-Scientist (MD/PhD) | REMOTE (US) | Full-Time

Innolitics builds AI/ML software for medical devices — the kind that detects ear infections, tracks metastatic cancer, and plans radiation therapy. 60+ FDA clearances. We need engineers who want their work to matter.
We're a remote-only firm (since 2012) that does engineering, regulatory, and cybersecurity under one roof. Our team includes MDs, PhDs, and software engineers. Clients range from Series A startups to large device companies.
We're hiring for three roles:

1. Physician-Scientist (MD/PhD) — Biostatistics & AI Software Development
MD + PhD in biostatistics, bioinformatics, epidemiology, or a related quantitative field. You'll design biostatistical plans for AI validation studies (MRMC, standalone, prospective), build production-grade statistical software and data pipelines, write FDA-facing statistical sections, and analyze large clinical imaging datasets. Fluent in Python and/or R. This is not a pure research role — you'll ship code that gets FDA-cleared and deployed in clinics.

2. Senior Web/Mobile Medical Device Engineer
5+ years SWE experience. 3+ years each in web and mobile. Fluent in TypeScript and Python. You'll build medical device software and produce FDA-facing technical documentation. Cross-functional role bridging engineering and regulatory teams.

3. Medical Device Software Engineer
3+ years SWE experience. Fluent in Python, C++, or TypeScript. Heavier emphasis on software development initially; you'll grow into regulatory documentation work over time.
All roles involve writing production code for medical devices, authoring documentation for FDA submissions, and working directly with clients. No prior medical device experience required — we'll teach you.
Why engineers stay here:

Agentic AI tools (Claude Code, etc.) are part of our workflow. We treat them as a impact multiplier, not a threat.
~1 hour of meetings/week for ICs. Flexible hours.
2 hours every Wednesday dedicated to learning ("10x Time").
Healthcare-only revenue. No debt. Never had a layoff.
We pay $300 for take-home exercises because your time has value.

Stack: Python, TypeScript, C++, R, Django, React, TensorFlow, PyTorch, scikit-learn, Qt, Terraform.

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed in 6-10 Weeks

We are building an AI-powered civilian protection platform — real-time threat intelligence for non-combatants in conflict zones. Think Waze for airstrikes. Multi-model AI pipeline (Gemini) ingests OSINT, verifies it through gated analysis, and pushes geolocated alerts to offline-first mobile clients. People die when information is late or wrong — we are solving both problems.

We are currently unfunded, operating on sweat equity. Pre-seed is 6-10 weeks out. This is not a side project — we have a working system, a pipeline of 39 vetted applicants, and a founder who has been shipping code daily for months. But I will not sugarcoat it: right now, this is nights-and-weekends until funding closes.

We need two people:

1. Systems Architect / Full Stack Dev
You see the whole board. You think in pipelines, failure modes, and deployment constraints — not just endpoints. You will own the technical architecture of a system where a bug isn't a bad UX, it's a missed warning. Python/Django, MongoDB, LLMs (Gemini/Vertex AI). Bonus: Flutter, OSINT, geospatial.

2. Implementation Partner / Full Stack Dev
You ship. Relentlessly. You take a spec and it's done by morning. You don't wait for perfect — you build, test, push, iterate. Same stack: Python/Django, MongoDB. You will be the person who turns architecture into working product at startup speed.

Both roles require exceptional drive. This is a founding team — not a job listing.

Compensation (No BS):

• Now: Sweat equity only. You're building your stake.


• Pre-Seed (6-10 weeks): $3,000/month + equity per contributor.


• Seed (6-12 months): 75% market salary + equity. Increases from there.

  If you need full salary today, this is not for you. If you want to build something that actually matters and you're willing to bet on yourself for 6-10 weeks to get there — keep reading.

  Stack: Python, Django 4.1, MongoDB, Flutter, Vertex AI (Gemini), Docker, AWS.

  Apply: [email protected] — Send your resume or GitHub and tell me what you'd ship in your first week.

Estuary | US-Based / Remote | Full-time – https://estuary.dev/

Estuary is a VC-backed, post–Series A startup powering right-time data replication and transform — from sub-second CDC replication to terabyte-scale OLAP data flows.

We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.

We’re hiring for:

Senior & Staff Backend Engineers

5+ years backend experience; Go required, Rust a plus. Own core systems powering real-time data pipelines. Build complex API/database integrations, improve connector frameworks, and tackle deep challenges in performance, reliability, and developer experience.

Backend Engineer (Integrations) – 2–4 years of backend experience. Help expand and maintain our catalog of real-time data connectors to SaaS tools using Python. You’ll work closely with experienced engineers to build and optimize integrations with third-party systems, while deepening your skills in infrastructure and stream processing.

Solutions Engineer - Work with the founding team to help customers use Estuary effectively. Collaborate closely with engineering and product, shape how users integrate real-time data, and feed insights back into product development.

What we’re looking for: Engineers who care about building reliable, maintainable systems and enjoy working with complex APIs and data flows. We value curiosity, clear communication, and a willingness to learn.

Bonus points for experience with CDC tools, open source contributions, or fast-paced startups.

focal | Head of Technology & Applied AI | Remote/Onsite/Hybrid (US)

focal is an institutionally-backed, next-generation venture firm. Currently investing out of fund II (2025 vintage), we lead at the start, often pre-incorporation, with up to $1M. The next great venture firm won't just use AI. It will be AI-native from the ground up - seeing sooner, deciding faster, and building systems that compound across every founder, deal, and outcome. That's how a 5-person team beats a 50-person firm. We're building that firm. You'll own how it gets built.

This is a long-term, high-impact founding role with meaningful financial upside (carry in funds) and ownership over how the firm is built. You'll join as our 5th team member and partner closely with our GPs in a flat structure.

Your core responsibility: Build and own the AI-native operating system that becomes our structural edge.

Why this might be interesting to you: you get carry in our funds, full ownership over architecture and roadmap, and a problem space that's genuinely unsolved. Venture firms haven't been technically reimagined in decades.

Who you are: A founder-type. A builder: Highly technical, deeply curious, high-output, high-agency. You move from idea → architecture → shipped - fast. You want real ownership over process and outcome, not a seat at someone else's table. You've built things from scratch that worked, and you can point to them.

Comp: carry in our funds (your upside is tied to fund returns), competitive cash, 100% healthcare, 401(k), 6 weeks PTO, 3 months parental leave, budget for compute/tools.

We're not asking for a resume. Send us your LinkedIn (and X if you have it) along with your favorite thing that you've built and tell us why you're proud of it. GitHub, side projects, demos, whatever.

Tetricus Labs | https://www.tetricuslabs.com/ | Full-Stack Engineer (Contractor) | Full-Time | Remote (APAC, UTC+5:30 to UTC+10:00) AND Remote (US)

We're a health tech startup building Personily, a psychiatric care platform that combines structured clinical measurement (PHQ-9, GAD-7, LPFS), passive sensing (sleep, steps, location), AI session transcription, and supervision tooling into a single platform for clinicians and patients.

We're looking for a full-stack engineer who can own features end-to-end across our stack:

- Backend: Python, FastAPI, PostgreSQL

- Frontend: React, Vite

- Infra: Kubernetes, GCP

You'll be building secure, high-performance APIs and clinician-facing interfaces, and taking features from concept through deployment. We're a small team, so you'll have real ownership and work closely with clinicians to shape how the product evolves.

Good fit if you: have strong fundamentals across the full stack, care about security and performance, and are comfortable diving deep into ambiguous technical problems.

We are hiring fully remotely in both APAC and the US, with a HQ in NYC.

Weekly progress towards agreed goals is expected, with payments due after results reviews. Mostly async communications. Please mail your free form introduction to [email protected] with words "decompile job" in subject.

Starbridge | Senior Engineers (Kotlin/Java/React/Typescript) | NYC or Remote | Full-time | starbridge.ai

Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.

Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini.

Apply: https://starbridge.ai/careers and mention HackerNews or email [email protected] with your resume.

RINSE | REMOTE or San Francisco, Los Angeles, Chicago, Boston, New York, New Jersey, Seattle, Austin, Toronto, or Washington DC | Software Engineer | Full-Time | Salary: $80k-$200k USD | https://www.rinse.com

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.

Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.

We're open to both newly-graduated engineers or more senior engineers, provided they meet our bar. We're particularly interested in true full-stack engineers, with strong React / Typescript / CSS skills to complement comfort in a Python / Django environment. We're also seeking engineers with experience leveraging AI to automate complex operational processes.

We're particularly interested in someone with significant React Native expertise at the moment, as we work to improve the apps our customers, delivery valets, and partners use.

You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.

Search term bingo: Logistics, Django, Python, Optimization, React, React Native, Postgres, Mobile Engineer, Automation, Delivery, OR-tools, Forecasting

We’re a start-up company, we are building a local-AI camera OS that replaces cloud CCTV: SigmaStar cameras → RTSP/ONVIF → HDMI node → on-device AI (offline-first).

1. Hiring: OS / Device Lifecycle Engineer (Secure Boot / OTA / Identity) (Remote, UK/EU preferred)

We already run RTSP + inference. Now we need the person who owns several year device reality.

You will own (single layer ownership):
Secure boot / trust chain (ROM → U-Boot → kernel → rootfs)
OTA updates + rollback strategy (A/B, recovery modes)
Device identity & lifecycle (provisioning, key rotation)
Failure recovery (power loss, corrupted SD, watchdogs)

You must be able to answer directly:
SD vs eMMC vs NVMe tradeoffs + corruption mitigation
Brown-out behavior, thermal throttling, BSP maturity
Camera ISP/NPU concurrency constraints + vendor SDK realities

2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)

We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.

You will own:
Independent review of firmware/bring-up assumptions
Validation of performance, thermals, power behavior, stability
Reproducible test plans (what breaks, how to detect, how to recover)
Documentation that prevents knowledge living in one head

If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.

Deep Systems | Senior DevOps Engineer | Remote EMEA, APAC, and Americas | Full-time

I am building a DevOps team at a capital markets tech company most people haven't heard of — but some of the world's biggest financial institutions run on our platform. 300B+ messages/day. 99.99% uptime. Mostly on-prem, Linux, purpose-built hardware.

You'd be working on systems support, tooling, and helping build a custom observability platform in Python — because off-the-shelf monitoring doesn't cut it at this scale.

Capital markets / FIX experience is a plus, not a requirement. Appetite for learning is.

The vibe: small global team (US/APAC/EMEA), fully async, deeply technical. Leadership still codes. No hand-holding, no fluff.

Mainly focused on US and EMEA hires (we currently have people clustered in Belfast and North Macedonia); for APAC, we have solid leads. We don't have salary expectations to publish. We are open to different engagements given regional and your personal factors, including contract, W-2, contract-to-hire, etc.

Lead Full-Stack Engineer
Marker Learning | Remote (U.S. only) | Full-time | Engineering | 185-250k

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.

Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

Reach out directly with your resume and why you want this position to [email protected]. Make the subject "Lead Engineer Application (I am not a bot)".

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Prior Labs | Berlin / Freiburg / NYC | ONSITE & REMOTE (EU) | Full-time

Tables power every clinical trial, financial model, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.

The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.

ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.

ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.

Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.

Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.

Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. With backing from Balderton, XTX Ventures and leaders at Hugging Face, DeepMind, and Black Forest Labs. Comp competitive with top AI labs, meaningful equity.

PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Spotlight roles:

* Engineering Lead

* Product Software Engineering (Quantitative Modeling)

Ongoing hiring:

* Bayesian Software Engineering

* Program Synthesis Engineering

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

Tether - https://tether.io/ - we are hiring for multiple roles 100% remote.

Fullstack Developers

You'll work across the JavaScript and TypeScript layer of our local AI stack. Depending on the project, you might build user-facing applications (mobile or desktop) or contribute to the platform layer that bridges our C++ inference engines with the app ecosystem. Either path puts you at the heart of making local AI usable: whether you're crafting polished product experiences or building the SDK and bindings that other developers rely on.
This role suits engineers who thrive in a full-stack JS environment and want to be part of a system where AI runs privately, locally, and fast.

Apply at: https://tether.recruitee.com/o/middleware-engineer-fullstack...

Lead React Native Engineer and React Native Engineers

You will be working on developing cutting edge mobile applications integrating crypto wallets and defi features.

You will also contribute to backend components when needed to support mobile features and unblock mobile delivery.

For Lead - apply at: https://tether.recruitee.com/o/lead-software-engineer-mobile...

For Software Engineer - apply at: https://tether.recruitee.com/o/software-engineer-mobile-deve...

Product Engineer:

You'll own the vision and execution of local AI products, from roadmap to release. Half your time goes into code, the other half into alignment: defining what to build, why it matters, and how to ship it well. You'll lead a pod of engineers across the stack, ensuring that the power of on-device AI translates into products people actually want to use.

This role is for builders who care deeply about the end result: making local, private, and powerful AI accessible through thoughtfully designed products.

Apex Dental Partners | Full-Stack Developer | Dallas, TX (Remote US or Hybrid) | apexdp.com

We're a Dental Support Organization running 59 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.

Stack is primarily Rails 7.1 (Hotwire+Stimulus.js), with some React/Electron, C# .NET (OpenDental), and Go — all on AWS.

You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.

Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

Decisionly | Senior Software Engineer (Backend) | Full Time | Remote (US based)

Decisionly is building AI-powered dispute decisioning for card issuers, eliminating cost and enabling compliant, scalable card operations.

We're looking for someone who is excited about the idea of working with a small team to solve a real pain point for credit card issuers. You'll need to have the ability to think from both a technical and product perspective to help translate a complex business process into a scalable, automated system.

CareMessage | Senior Software Engineer I (L3), Messaging Team | Full-Time | Remote

CareMessage is a healthcare technology nonprofit that powers patient communication for 400+ safety-net healthcare organizations — FQHCs, free clinics, and tribal health centers serving low-income and underserved populations.

You will lead the technical direction of our messaging platform, the system behind every SMS, voice call, and multimedia message we deliver. You will design delivery pipelines, build consent management workflows, architect Twilio integration layers, and handle the sharp edges that come with messaging at scale: retry logic, opt-out compliance (TCPA, A2P 10DLC), delivery optimization across carriers, and AI-driven message categorization.

You'll likely thrive here if you:

- Have 5+ years building and scaling backend systems

• Are strong in Ruby on Rails and Javascript with solid SQL chops

  - Enjoy owning complex features end-to-end, from design through production support

  - Think in terms of edge cases, failure modes, and delivery guarantees

  - Want to mentor other engineers and shape technical direction

  - Care about building infrastructure that has direct impact on patient outcomes

  This is a senior role with shared team lead responsibilities. Small, mission-driven team with meaningful ownership. Equitable pay regardless of location.

Empire Flippers | Remote (no office), all timezones | Full-time | https://empireflippers.com

Empire Flippers is a true global-remote company with travel in our DNA and employees scattered across 5 continents and all sorts of countries. Since I joined 6 years ago, I've personally been to India, the US, Brazil, Ecuador, Colombia, Mexico, the Philippines, China, Japan, Thailand, the UAE, all while working remotely and coding our Ruby on Rails + React app. More about us here: https://empireflippers.com/about-us

Though not as well known in the Hacker News / venture-backed startups sphere, Empire Flippers is widely considered the #1 marketplace for buying and selling online businesses in the 5 to 8 figure USD range.

Think of businesses like --- that recipe site you landed on as the first result when you googled "best chicken tikka masala recipe". Or the Amazon FBA seller whose product you purchased when shopping for "Widget XYZ" (with Amazon FBA, these ecommerce businesses never touch inventory and so it's a fully online business).

Turns out these type of businesses may be earning 10s of thousands of dollars per month in profit (or more!) and when the (often first time) founder is ready to sell, Empire Flippers is the #1 place to do it safely, securely and at a fair market price.

Before I joined Empire Flippers I only had a peripheral understanding of this space, but now that I've been steeped in this industry I can say that this "mini M&A" world is just as exciting as the high-flying unicorns (and decacorns) that we read about daily on Hacker News.

The company is hiring for a few different positions (both technical & non-technical), all of which can be found here: https://empireflippers.com/careers

But in particular, I'm hiring a Ruby on Rails developer to help me continue to build out new features in our Platform, both for customers and to help run our (very extensive) internal operations of vetting incoming businesses, facilitating their sale, and migrating them to the new owner after they've been purchased.

That job ad can be found here: https://empireflippers.com/career/ruby-on-rails-developer/

As mentioned, we are a global-remote company that hires people of all nationalities located in any country in the world.

Hope to see your application soon, and with any questions feel free to email me (Ben) at beng at empireflippers.com

Small & Stealthy | Flutter Developer | REMOTE (Global) | Contractor

We are building mobile products with a small, fast team and want a Flutter developer who is unusually strong at directing AI-driven software delivery. This is not a traditional "write the code yourself" role. We want someone who can decompose product and technical work clearly, set up coding agents and containerized environments so they can run independently, let them execute with very wide autonomy, and then use AI again to review, challenge, and validate the resulting commits. The standard here is technical excellence without manual coding as the primary lever. 100x engineering is the norm.

You might be a fit if you:

- are deeply experienced with Flutter and mobile product development

- are comfortable leveraging AI agents to plan, implement, test, and commit code with minimal guardrails

- can use AI-based review workflows to inspect commits, spot regressions, and maintain quality without doing line-by-line manual coding yourself

- have strong product and engineering judgment, and can tell when an AI-generated solution is structurally right vs. superficially plausible

- own and regularly use both a physical Android device and a physical iPhone/iPad for live app testing

- are familiar with provisioning, signing, installing, debugging, and validating Flutter apps on real devices, not just simulators

We care a lot about velocity, correctness, and taste. We are specifically looking for someone who can treat AI as the execution layer while still owning architecture, quality, release readiness, and real-device validation.
