SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Supabase | Customer Reliability Engineer (CRE) | Remote | Full-time | https://jobs.ashbyhq.com/supabase

Fully remote, fully async, fully open-source.
A CRE is a point of contact available, both internally and externally, to advise on best practice. Normally, they are knowledgeable in a specific area (i.e. Realtime, Postgres) but they aim to be generalists on the platform as a whole. They do not have specific customers that they help; instead they get involved with deeper, longer-running cases to achieve an outcome.

Looking for more of a focused development role? Sure thing, we have many roles open!

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.

Support engineers (junior to early-mid) who enjoy being on the front line of production support (monitor live systems, respond to partner/user issues, triage/debug, and escalate). Formal Verification Engineers with hands-on experience in formal methods to work on machine-checked proofs of blockchain protocols and smart contracts.

Tech stack: Doesn't matter, we'll teach you. But we work mostly with Rust.

Open roles:

* Software Engineer, https://commonprefix.notion.site/sw-folk

Build is a full-stack cloud platform — we own the stack from bare metal up. Our customers are engineering-led SaaS teams who've outgrown their current setup and want effortless deployment, real environments, and predictable pricing without the infrastructure overhead. Think teams escaping from Heroku, scaling past Vercel/Fly.io, or trying to escape AWS/GCP/Azure complexity.

We're hiring our first Technical Account Executive. This is a full-cycle role — you'll own outreach, discovery, and demos through to close, partnering closely with the VP Sales.

We're looking for someone with 4–7 years in devtools or cloud infra space who can hold a real conversation with engineers and understand what's actually broken in their setup. A background in cloud/devtools sales or Solutions Engineering but ready to own the whole cycle are both strong fits.
