Land your dream remote job

Namecoach/Euphonia | Founding Voice AI Engineer (part-time, path to CAIO) | SF or Remote | REMOTE | Contract / Part-time, ~$30-120/hr by seniority, potentially converting to FT

Namecoach has spent 10 years building the largest verified pronunciation dataset of its kind: ~2M self-recorded name pronunciations, plus a large corpus of human-verified phonetic spellings.

We're now building Euphonia (https://euphonia.namecoach.ai/), a provider-neutral middleware layer that makes any TTS engine pronounce names, acronyms, and other out-of-vocabulary terms correctly. The new wave of TTS (models from OpenAI, ElevenLabs, etc) sounds great but gives you almost no phoneme-level control, so it gets lots of names and words wrong and you can't easily fix it. We sit in front of these engines and fix it.

We want real depth in speech and phonetics: grapheme-to-phoneme, IPA, ASR/TTS internals, and the ability to build and evaluate models around them (the recognition and G2P side especially). You should be comfortable shipping with agentic dev tools like Claude Code and Cursor. This is a 0 to 1 founding voice AI engineering role with a genuine path to Chief AI Officer for the right person.

Part-time to start (flexible hours, ~2hr/day overlap with US Pacific), with a paid take-home and a paid trial month before anything longer term. Potential conversion to full-time role. Series A closed, bridge to B in motion.

Full JD: https://wellfound.com/l/2ChdJ2

Email [email protected] with a short note on what interests you and a link to something you've built. G2P / TTS / ASR open-source work gets read first.

Portless | AI Engineer (Founding seat) | Remote (North America) | $180k-$230k

AI usage today is basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows yet. This is a founding seat to build that: shipping high-impact agentic workflows yourself, plus reusable building blocks (APIs, MCP tools, docs) so any team can build their own.

Example first project: an agent for inbound invoice questions — reads the question, pulls the right invoice, drafts a context-aware reply — turning an hour of manual work into ~30 seconds.

Need: 3+ yrs SWE with 1-2+ yrs shipping production AI systems, 10+ real agentic/LLM workflows built end-to-end, a genuine platform mindset (built tools/infra for others, not just yourself), strong Python and/or TypeScript, and relevant sector background (e-commerce, 3PL, logistics, or similar B2B).

Nice to have: RAG pipelines, vector DBs, multi-step agent orchestration, eval frameworks.

BW Events Tech | Senior Software Engineer | REMOTE | CONTRACT (~40 hrs/wk, hourly, rate DOE + location) | Python/Django/React, AWS + GCP

We build ShowUp, the software that runs live events end to end: check-in, badging, session scanning, lead capture, exhibitor portals. It runs in real time, on-site, where there's no second chance to get it right. We work with teams of every size, including three of the Fortune 5, across hundreds of events a year worldwide.

We're hiring one senior engineer to own core platform development - improvements, integrations, reliability — and ship it end to end. You'll work with our eng lead, who sets architecture and reviews the work, while you run with a lot of autonomy. We want someone who can take an ambiguous problem, scope it, and ship it without needing it broken down first. Builder role: no reports, real ownership.

We're an AI-forward team and lean on AI tooling heavily to punch above our size; we expect you to use it to amplify your judgment, not replace it.

Stack: Python, Django, React, on AWS and GCP. More detail: https://docs.google.com/document/d/18F2bypRBJxQDTsTNdazpz2SB...

Looking for: 8+ years, senior experience owning complex domains, fast ramp in unfamiliar codebases, strong judgment on ambiguous work, fluent everyday use of AI tools, clear communication. Event-tech or integration-heavy background is a plus. Rate: 60-100/hr USD DoE.

Individuals only — no agencies, staffing firms, or third-party recruiters.

Apply: email your resume to [email protected]

Lumen Labs | Simulation/RL Integration Engineer | REMOTE (US/Canada), then ONSITE SF from fall 2026 | $130k–200k + early equity | Visa OK

Lumen (https://lumenresearch.ai) is building the cognitive layer for physical AI. Most robotics efforts today learn from thousands of hours of human teleoperation; we think that has a ceiling. White paper: http://lumenresearch.co/paper

Team of two ex-founders — you'd be #3. Pre-seed, runway well into 2027, raising a seed later this year.

We test many model architectures against many sims, and hooking them together is our biggest pain point. We use Gymnasium and Shimmy as the plumbing and upstream useful pieces as open-source contributions. You'd build per-sim adapters to a shared interface contract, bridge single-env vs. GPU-vectorized and sync vs. async paradigms, and own our eval harness.

Looking for: strong Python, Gymnasium (especially the vector API), hands-on experience with Isaac, MuJoCo, or Gazebo, and a track record of getting models running in sims where they didn't before.

Email [email protected] about you and your projects — link one where you got a model working in a sim it wasn't built for and you'll jump the pile.

Sports Trading Exchange | Founding Engineer / CTO | Remote USA | $140–200k + meaningful equity + founder seat available

We're building a peer-to-peer exchange where fans buy and sell positions in individual athletes, like a stock. Real money, central limit order book, mechanical settlement against a published rules-based rating computed from official on-field stats. There is no house. Fans trade against each other like a prediction market.

We are far along on everything except the build. Rating methodology is designed, legal structure is scoped with counsel, payments and data vendors are selected, and we ran a beta this past NFL season that drew ~1,000 organic users and 21,000 trades in four weeks. The founding team was part of Founders Inc, and we are about to open our seed round.

We are hiring the engineer who owns the entire technical build, with no inherited architecture and nobody between them and the problem:

Matching engine and order book
Rating and settlement engine, deterministic, computed from official stats
Ledger, custody, and the real-time data pipeline
Every architecture decision, including one we have deliberately left open: on-chain vs off-chain custody and settlement at v1

Looking for someone who has built correctness-critical, concurrent systems. Trading, exchanges, payments, or comparable. Language is open. We care about systems depth, not a specific stack. Two non-technical founders, so you would own the technical domain completely and be the technical voice with investors and eventually regulators.
Email me [email protected] if interested, thanks

Trinsic | Senior Product Engineer | REMOTE (Europe) | Full-time

We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards.

Role

• Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning.


• This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end.


• You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step. Revenue is surging, we need judgement to help shape the product.


• Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it.


• You care deeply about user privacy and data security. We work on identity. Sloppiness here is not an option.

  Stack & ways of working



• .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD.


• Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful.


• We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks.

  Comp & apply

  - Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time.

  - Apply: https://www.trinsic.id/careers/senior-product-engineer?utm_s...

  If you're in a workable timezone and excited about identity infrastructure, I'd love to talk.

Ditto | Engineering & Product | Remote (US: Atlanta, Austin, SF, Seattle) + APAC | Full-time
https://jobs.ashbyhq.com/ditto

https://docs.ditto.live/home/about-ditto

I've been obsessed with CRDTs since I first saw them at Strange Loop years ago, and I still can't quite believe I now get to work on them for a living — in some of the most challenging environments there are: disconnected, degraded, contested, out where the cloud isn't. If that's your kind of problem, come build with us.

Ditto is the edge-native data platform that keeps distributed systems in sync when the network doesn't cooperate — an offline-first, CRDT-based layer syncing any device (phone, vehicle, sensor, server) over Bluetooth LE, P2P Wi-Fi, LAN, and tactical radio, with or without connectivity. Same core, commercial to defense; operationally deployed and network-agnostic. The problems are the fun kind: conflict-free replication with no server and no synchronized clock, multi-transport routing that never drops the connection, moving a coherent picture over links as thin as an HF radio shot, and human-in-the-loop robotics/autonomy where a detection may have to be physically carried by a moving node. Concept to field in days, not months.

Most roles are open to anyone authorized to work in the U.S.; Public Sector and forward-deployed roles require U.S. person status. Remote in the U.S. (hubs: Atlanta, Austin, SF, Seattle) unless noted.

Acme | Remote / In-person (flexible) | Full-time | Founding Full-Stack Engineer

Acme is building a product. We are an early-stage company at the ground floor — no code yet, no customers yet, just a clear vision and a bias for action. We are looking for a founding engineer who wants to build something from nothing: architect the system, write the first line of code, ship the first version, and grow alongside the company.

What You'll Do:

• Build the product end-to-end — from database schema and API design to frontend UI and deployment infrastructure


• Make architectural decisions — choose the tech stack, set up CI/CD, monitoring, and dev environments


• Ship iteratively — get working software in front of users fast, then improve based on real feedback


• Set engineering standards — establish coding conventions, code review practices, and a culture of quality


• Influence product direction — work directly with the CEO on what to build, what to cut, and how to prioritize


• Own the infrastructure — provision cloud resources, manage deployments, and keep the app running in production

  Who You Are:



• 3–8 years of software engineering experience, preferably in early-stage startups or with significant side-project shipping


• Full-stack capable — comfortable across frontend, backend, databases, and infrastructure


• Ship-focused — 80% today beats 100% next month. Pragmatic tradeoffs between speed and quality


• Independent — thrive without a playbook. Figure things out, make decisions, communicate clearly


• High ownership, low ego — care about the mission and the team, not about who gets credit


• Product-sensible — good judgment about what users need and what can wait

  Compensation: Competitive salary + meaningful equity (2–5% range)

  How to Apply: Send a note to the CEO with what excites you about early-stage building, a link to something you have built (GitHub, portfolio, side project), and why Acme specifically. No formal resume required.

FusionAuth | Principal Software Engineer, Senior Java Engineer - Cloud, Account Executive | Varies between REMOTE (in USA, also in Europe but only for the account exec position) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges for the Principal Software Engineer it is 225k-270k, but the Euro positions don't have them :(

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.

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

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)

* 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)

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

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.

Syntropic (thesyntropic.com) | Founding CTO / GPU Systems Engineer | Remote (US) | Equity-heavy

We compress LLM KV cache. Measured: 8× at 3-bit with 0.43% quality delta (GPU-validated); 22× live end-to-end on a 5-tenant workload, GPU-verified this week (quantization × prefix dedup, decomposition always stated); 16.89× tenant density on a single V100-32GB. Validated across Mistral/Qwen/Llama with zero re-tuning. 90+ patents pending; design-partner pipeline; seed round in motion.

The gap: our throughput path is a reference implementation. First job is the fused Triton/CUDA dequant+attention kernel — turning a validated 22× memory result into production speed. Then you own the serving stack.

Process: call → NDA → paid 1–2 week trial on the real kernel → decide together. We report negative results straight; you should want to work somewhere that does.

Make Waves | https://makewaves.fm | multiple roles | FULLTIME (4-5 days), 4DWW | ONSITE - HYBRID - REMOTE (NL preferred, EU considered) | Amsterdam, NL

We are a DIY distribution and promotion platform for independent artists and labels. In an industry that's notoriously over-complicated and dominated by players who only care about volume, we're building something kinder: a genuinely helpful way to release music and build a following.

We already support more than 20,000 users in their music careers. In the Netherlands, we're a leading provider of independent digital music distribution, and we continue to grow steadily on an international scale.

We are actively looking for a senior full stack engineer and a medior operations and automation engineer. Unfortunately we can’t offer relocation or visa sponsorship.

Our stack relies on python, fastapi, postgres, next.js, react, typescript, gcp, terraform, k8s, redis, dataflow, see job descriptions for more details.

Grace AI Control | Founding CTO | Wilmington, NC (Eastern NC preferred) or REMOTE (US) | Full-time | Equity-first (~2-4% + modest early salary) | https://www.graceaicontrol.com

We're building accountability infrastructure for enterprise AI in regulated financial environments — the trust, evidence, and audit layer that lets banks and regulators actually rely on AI. Pre-revenue, ground floor, looking for the founding technical leader who will architect it and write the production code that becomes the company's core.

You're likely a current Principal/Staff Engineer, Senior Architect, or Tech Lead ready for your first executive seat while still building hands-on. What matters most: strong software/platform architecture and distributed systems; real security-engineering depth (cryptography, PKI, key management, immutable logging, evidence integrity); cloud-native infra (AWS, CI/CD, IaC) and enterprise API design; and enough fluency with modern AI/LLM systems to grasp why AI needs oversight and accountability. Bonus: RegTech/FinTech/identity background, or nCino/Salesforce/core-banking integration experience.

This is a mission and a ground-floor opportunity, not a paycheck play. Compensation discussed directly.

Must already have U.S. work authorization; no visa sponsorship.

Kinxshn | Forward Deployed Engineer - backend - python | REMOTE (Europe) | Full time | Funded

We build AI agents that run real operations. Humans talk to our agents to run commercial real estate: leases, contractors, invoicing, accounting. We're live in production across several European jurisdictions, with real customers and real money.

We need a Forward Deployed Engineer to own a client-facing use case end to end: a strong backend engineer who is also the face of the team to the customer.

The job:

- Talk to clients directly and often. Pull requirements out of messy conversations, explain tradeoffs, own the relationship

- Turn jurisdiction-specific lease rules, tax and accounting mappings, client-specific workflows into tools our agents call

- Ship to production in your first month, then keep it alive

What we need, in this order:

1. Self-driven, real ownership. You'll have a lot of freedom and support, but the use case is yours end to end - nobody will be feeding you tickets.

2. Excellent English and real customer-facing experience. You'll be on client calls every week.

3. Serious backend experience. You've shipped and operated production systems, and can work as the only engineer in the room. We use AI tools heavily, but we don't vibe code: your engineering judgment and review are what make the code shippable, and you own what you merge.

4. LLM agents in production, or you ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call.

Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain/LangGraph, operator or consulting background.

We're a small senior team across Europe and South America. For this role we need you in Europe.

Competitive comp - we have no salary bands, for the right person we'll stretch.

Apply: [email protected], subject "HN - Forward Deployed Engineer", salary expectation and CV attached - skip the skills inventory: tell us about something hard you shipped and a customer you made happy.

Opendate | Senior Full-Stack Software Engineer | Remote (US) | Full-time

Opendate builds the ticketing platform powering independent music venues across North America.

We're looking for a senior engineer who is pushing the boundaries of AI-assisted software development.

Everyone says they use AI. We're looking for someone who has gone much further—someone who is constantly experimenting with new workflows, building agents, automating entire pieces of development, and rethinking what one engineer can accomplish.

Our engineering team believes AI is fundamentally changing what great engineering looks like. We want people who are helping define that future—not waiting for someone else to.

Our stack includes Ruby on Rails, React, PostgreSQL, AWS, Sidekiq, and Stripe, but we're far more interested in how you build than the specific technologies you've used.

If you're excited by questions like:

How can AI own an entire feature from design to deployment?
What engineering work still requires humans, and what should be automated?
How do we move dramatically faster while maintaining an exceptionally high bar for quality?
What does an engineering organization look like when every engineer has AI teammates?

...you'll probably enjoy working with us.

If this resonates, we'd love to hear from you.

ProxyBase (https://proxybase.xyz) | Rust Backend Engineers & Full-Stack Developers | Remote (Global) | Full-Time | $100k-$160k + Equity

Hey HN, we’re ProxyBase. We’re building an API-first, fully headless SOCKS5 proxy network designed specifically for autonomous AI agents, LLM tool-calling, and large-scale web scraping.

Most traditional proxy networks operate in a bit of a gray area—they buy bandwidth harvested from sneaky, hidden SDK bundles embedded inside free apps. We're doing things differently:

100% Ethical Sourcing: We pay our node operators directly. People run our open-source CLI client to share their bandwidth and earn microcredits in real-time. It’s fully transparent, consent-driven, and compensated.

Built for Swarms, Not Dashboards: AI agents and automated workflows can provision, utilize, dynamically route (via metadata in the SOCKS5 auth string), and settle proxy fees entirely programmatically using US based stable coins without ever touching a manual web dashboard.

Our Tech Stack:

Backend: Rust (Actix-web, SQLite/DashMap, WebSockets, Yamux stream multiplexing)
Frontend / Desktop: React, TypeScript, Tauri (our client-side bridge app)

What we're looking for:

Backend Engineer (Rust): Help us scale our high-concurrency SOCKS5-to-WebSocket relay gateway and real-time ledger settlement engines.
Full-Stack Developer (TypeScript / Tauri / Rust): Own our local proxy bridging software, client-side developer portal, and integration libraries.
If you like systems-level programming (TCP/UDP, tunnel multiplexing, concurrent state) and want to work on clean, developer-first infrastructure, we'd love to chat.

Drop us a line at

[email protected]
with a bit about what you've built.

Dashdoc | Product/Software Engineer, BeNeLux Expansion | Dutch-speaking | REMOTE / EU | Full-time | €50k–€80k | React, React Native, Python/Django, PostgreSQL, GCP

Dashdoc is a SaaS Transport Management System for road freight. We help carriers and shippers run transport operations on one shared platform.

We’re hiring a product-minded engineer to help us expand in Belgium and the Netherlands. Local specifics: e-CMR mandates, digital waste regulations, Dutch/Flemish accounting standards, regional carrier workflows often block deals or deployments. Your job is to find those blockers and turn them into shipped product.

You’ll work directly with customers, sales, CSMs, and product. You’ll be able to spend time with carriers in Belgium and the Netherlands, watch users use the product, read contracts/regulations, then spec, build, deploy, and measure the features yourself.

Stack: React, React Native, Python/Django, Django REST Framework, PostgreSQL, Google Cloud. We use Shape Up, ship continuously, and use AI coding tools like Claude Code, Cursor, and Codex.

Good fit if you speak Dutch fluently, write clearly in English, like owning ambiguous product problems end-to-end, care about simple UX and clean code, and enjoy deleting code as much as adding it.

Apply: https://dashdoc.welcomekit.co/companies/dashdoc/jobs/product...

Ashby | YC 19 | REMOTE | Hiring Engineering Manager (Americas) | $200k–$275k

Ashby is the all-in-one recruiting platform powering hiring at the world's most innovative companies. If you cmd+f "Ashby" you'll see that we're powering many of the job postings in this thread!

We’re looking to scale our engineering leadership team with technical leaders who want to raise the impact of a high-performing organization.

* Not Your Traditional "Jira-Manager": Our EMs are not classic delivery coordinators who shuffle meetings or build heavy processes. Instead, you will own people, hiring bar, technical judgment, and the health of our engineering systems.

* High-Autonomy Team: Because 80%+ of our engineering team is Senior–Staff+ level, our engineers already possess a high degree of ownership. Your focus is less on day-to-day task coordination and more on coaching independent owners, managing ambiguity, and raising team impact.

* Technically Credible Leaders: You will stay close enough to the work to challenge assumptions, review proposals, spot maintainability issues, and jump into the code to debug alongside engineers when needed.

* Organizational Advocates: Beyond your immediate team, you will act as an advocate owning the health and metrics of org-wide areas—ranging from CI/CD health and developer productivity to customer success collaboration and on-call sustainability.

* 100% Remote Async Culture: We maintain an even distribution of engineers across North America and Europe, optimizing for minimal process and maximum focus.

• Here's how we're thinking about AI at Ashby:https://www.ashbyhq.com/blog/engineering/ai-ashby-engineerin...

  * Full transparency on engineering levels + comp:https://www.ashbyhq.com/blog/engineering/leveling-and-compen...

  Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis. (While you won't always be shipping code, you are expected to hold a deep technical understanding of the system).

Kog (https://kog.ai) | GPU Engineer | Paris, France | REMOTE within a Europe-compatible timezone, one week per month onsite in Paris

We are hiring a GPU Engineer to work on the fastest LLM inference engine on standard datacenter GPUs.

You would own low-level kernel work in CUDA/PTX or HIP/CDNA ISA, the monokernel pipeline, profiling infrastructure inside it, scaling to the frontier MoE models that run in production, and building our own agents that optimize kernels and inference autonomously.

We generate 3,000 tokens/s per request on 8x AMD MI300X and 2,100 on 8x NVIDIA H200, at batch size 1, FP16, no speculative decoding.

At batch size 1, the decode is GEMV, so it is memory bandwidth bound, and MBU is what counts.

We rewrote the whole hot path ourselves, from the assembly on the chip up to the Transformer we designed around it, with the full decode running as a single persistent GPU kernel.

Try it at https://playground.kog.ai

Showing your code is part of the process.

If you are outside a Europe-compatible timezone, relocation to one is required.

3Play Media | Principal Front-End Engineer (Growth) | Boston, MA | 1-day-in-office hybrid or fully remote (USA only) | Full-time | 3playmedia.com | $200–250k + bonus + equity

3Play makes content accessible across disability and language. Our human-QA'd captioning, audio description, subtitling, and dubbing services are used by over 10,000 media, higher ed, creator, enterprise, and government customers. We’ve worked on really cool projects: recent examples including captioning the 2024 Paris Olympics and providing quality AI dubbing for high-profile YouTube creators.

I'm leading the Growth team, and we're working to build new, beautiful UI experiences on our long-loved services. Our stack is a Remix/Rails product and Astro/Sanity marketing site, both backed with modern design system foundation (what you might expect with Typescript, Tailwind, ShadCN, Tanstack, etc). I'm looking for a principal-level engineer with strong taste in front-end: someone who cares about UX and styling, takes accessibility and page weight seriously, builds strong validation / testing harnesses, and keeps a dependency tree sane instead of letting it metastasize.

The other part of this role is contributing to our agents and workflows. We've invested heavily here with the right mix of enthusiasm, guardrails, and budget. You'll have heavy influence over how it evolves: what we hand to agents vs. keep in human hands, how work gets specified and parallelized, how we keep the results beautiful, and where the security and review gates live. There’s a ton of opportunity to work with the latest AI tooling and determine best practices as the industry matures.
We’re a small team happily working over 15 years with high impact, high autonomy, and low bureaucracy. Come join us! Apply at https://www.3playmedia.com/company/jobs-post/?gh_jid=7761973.... Mention HN when you apply!

Colonist | Senior Product Engineer, QA Engineer | Full-time | Remote & async

Colonist (colonist.io) is a multiplayer board game platform. ~20 people, millions of monthly players, no middle management between you and the product.

You'll own features end-to-end and ship to a live player base within days. Right now we're evolving the core experience and building toward a multi-game platform. The mission is to become the internet's biggest board game platform.

This role is a good fit if you: want to see your work matter at real scale without a large team around you, are comfortable with ambiguity and don't need someone to define your tasks, and use AI tools as a genuine multiplier in your workflow.

This isn't a good fit if you: prefer a larger team with specialists for every layer, or are looking for a role with clearly scoped tickets.

You'll own the full bug lifecycle, wire tests into CI/CD as reliable quality gates, and partner with product and engineering to build testability in from the start.

Ideal fit: 3+ years in QA testing web apps, across both manual and automated testing with modern frameworks (Playwright, Selenium) and unit/component tooling (Jest, Vitest). Comfortable testing SPAs and REST APIs, with enough JavaScript/TypeScript to write and debug test code. Bonus points for React, Vite, monorepos, micro-frontends, GitHub Actions.

airCFO is an AI-powered accounting & finance services partner to 300+ startups (current/former clients include Anthropic, Replit, Harmonic), and we are building a platform to supercharge our service's capabilities. We're hiring a founding engineer to build the systems behind it: a retrieval/RAG context layer over all our tools, and the internal apps (TypeScript, Node, Python/FastAPI, React, Postgres, Claude + MCP) our teams use daily. We want someone senior who drives coding agents hard but refuses to lose the plot — clean architecture and a real mental model of the whole system. Production RAG/agents a plus, not a requirement. You'd report to a hands-on fractional CTO; small team, high autonomy.
