Build things worth defending.
We're a small senior team, and we grow carefully. No open roles are posted right now — but we always read serious applications.
Why engineers stay
Real engineering variety
SaaS one quarter, a native mobile app the next, an AI agent after that. You will not spend three years maintaining one CRUD screen.
Senior room, no theater
Small team, direct communication, no standup performances or ticket bureaucracy for its own sake. Ship, demo, improve.
Open source on the clock
Extracting and maintaining our packages is part of the job, not a weekend hobby. Your public work grows with your client work.
Craft is the metric
We review for quality, invest in tooling, and give estimates that include doing it right. No feature-factory burnout.
// open application
Think you'd raise our average?
Send us something you've built — a repo, a shipped app, a package, a write-up — and a few lines on the work you want to be doing. We read every serious application and reply to all of them, even when the answer is "not yet."
