Full Stack Engineer (San Francisco)

THE MISSION America's industrial base runs on systems built in the 1980s. Billions of dollars in critical components (F-35 parts, industrial assemblies, electronics, bolts, and hoses) still move through email threads, excel sheets, and disconnected ERPs. We're replacing that with an AI-native platform that makes aerospace, electronics, industrial, and defense supply-chain operations nearly autonomous. Faster quoting. Faster procurement. Full visibility. Real operational intelligence for the companies our nation depends on. QUICK FACTS - YC W25 company. Top 5% growth in batch - Raised $10M+ from investors including Paul Graham, SV Angel, Pear VC, and CRV - Team of 20 co-live in our Warsaw & SF Hacker Houses - 7 figure ARR transacting ~$50M a week through our system THE ROLE Our Full Stack Engineers work with the platform team and our forward deployed engineers to build the systems our customers run on. Most of that work means integrating with legacy ERPs and email-driven workflows that move real orders every day. - Full time, in person in San Francisco. This is not a remote role. - Backend-leaning: Svelte, TypeScript, Postgres. - Design, build, and maintain features end to end, from schema to UI. - Run several projects in parallel and get each one shipped. WHAT WE’RE LOOKING FOR - Absolute grinder. Interested in co-living (though not required). - You've shipped real full-stack products and can show us one: a GitHub repo, a live web app, or a Loom walkthrough. - You've designed systems on your own, not only built someone else's spec. - Strong in TypeScript and at least one frontend framework (React, Svelte, Next, etc). - Comfortable in SQL, preferably Postgres. You can write, optimize, and debug complex queries, not just call an ORM. - Comfortable with ambiguity. Priorities can change week to week. - Low ego, curious, intellectually honest. Focused on outcomes, not on being right. THE PROCESS Initial call with engineer → Technical screening → Quick call with founder → fly out to SF HQ for onsite (on us) → offer.
