Senior iOS Engineer

EngineeringRemote · WorldwideFull-time$170k – $230k + equity

About the role

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.
