Software Engineer (Warsaw)

The Mission
The West'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 supply-chain superintelligence that makes aerospace, electronics, industrial, and defense operations nearly autonomous. Faster quoting. Faster procurement. End-to-end supply chain visibility.

The Role
You'll join our Warsaw engineering team and build the product our customers run their quoting and purchasing on every day. You'll ship real features from your first week, with senior engineers reviewing your work and pulling you into design decisions.
Full time, in person in our Warsaw office, 9 to 5, Monday to Friday. This is not a remote role.
Svelte, TypeScript, Postgres.
Build features end to end, from schema to UI.
Up to one week of international travel per quarter (SF HQ or customer sites).
What We’re Looking For
3+ years building full-stack products.
You've shipped something you can show us: a GitHub repo, a live web app, or a Loom walkthrough.
Strong in TypeScript and at least one frontend framework (React, Svelte, Next, etc).
Comfortable writing SQL, not just calling an ORM.
You use AI coding tools every day and know where they break.
Fluent English.
You're comfortable working for founders in their early twenties.
Hackathons, meetups, or public speaking are a plus.
Low ego, curious, learns fast.

Initial call with engineer → Technical screening → Quick call with founder → fly out to SF/Warsaw HQ for onsite (on us) → offer.
