Gray is a native iOS app built with React Native and Expo — a voice-first terminal for people who run real infrastructure. You will own the surface our users touch every day: the Talk loop, the live terminal, the crew view, and the interrupt loop that makes Gray feel instant.
This is a senior, hands-on role. You will work directly with the founders and ship to the App Store every week.
What you will own
Own the iOS app end to end — architecture, performance, release
Make the voice loop feel instant: sub-second barge-in, smooth orb state transitions, careful haptics
Build the live terminal view — scrollback, key bar, color-tagged sessions — at 60fps
Keep the app honest on battery, memory, and background audio
Review designs critically; push back when a spec won't feel right in the hand
What you bring
5+ years shipping production mobile apps, with React Native depth
Real comfort dropping to native — Swift, audio sessions, background modes
A feel for motion and touch; you notice 80ms
Experience with streaming data over flaky mobile networks
You use a terminal daily and know why Ctrl-C matters
Nice to have
You've shipped a voice or audio product
Expo + EAS release experience
You run your own homelab or VPS
What we offer
Meaningful equity. Every role carries a real stake in Layer Gray, with a 10-year exercise window.
Remote, worldwide. Work from anywhere. We hire for the role, not the time zone.
Hardware budget. $4,000 for your machines, plus a home server allowance — you should run Gray on your own box.
Flexible time off. 25 days minimum, and we mean minimum. We track outcomes, not hours.
Health covered. Full medical, dental, and vision for you and your dependents, wherever you are.
Two offsites a year. The whole crew, one room, twice a year. The rest of the time, async.
Model subscriptions. Claude, GPT, and friends — every frontier model subscription, paid.
Learning budget. $2,000 a year for books, courses, and conferences. No approval theatre.
About Gray
Gray is voice-first AI you operate like a terminal. You speak; it runs real work across your machines — SSH sessions, multi-agent jobs, files, scheduled tasks — then speaks back. It is self-hosted, private by architecture, and built for the people who run the internet’s plumbing. Gray is made by Layer Gray, Inc.
