Backend Engineer — Core Platform

EngineeringRemote · WorldwideFull-time$160k – $220k + equity

About the role

Behind the voice loop sits a platform: accounts, sessions, scheduled jobs, the activity log, connections to sixteen external services and counting. You will build the boring parts beautifully, so everything else can move fast.

What you will own

  • Own the platform services — auth, billing, scheduling, the activity log
  • Build and maintain connectors: Slack, GitHub, Notion, Linear, and the rest
  • Design APIs that the app, the daemon, and the agents all share
  • Keep the platform stateless where the box is the source of truth
  • Hold the line on reliability — operators notice downtime professionally

What you bring

  • 5+ years of backend work in production
  • Strong API design instincts — versioning, idempotency, pagination
  • Experience integrating third-party APIs at scale, with their failure modes
  • TypeScript, Go, or similar

Nice to have

  • Billing/subscription experience (App Store, Play, Stripe)
  • You've maintained an OAuth integration through a breaking change

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.
