About the role

The mobile app is the surface a tech sees every minute they're on a job site. It needs to be fast, offline-aware, and feel like a native app — not a web view in disguise. You'll own the entire mobile codebase as the first dedicated mobile hire.

What you'll do

  • Own the mobile roadmap, in close collaboration with the founders and the rest of engineering.
  • Build new native features: photo capture, voice notes, offline queue, push notifications, deep links.
  • Drive performance: cold start under 2s on a 3-year-old Android, smooth 60fps scroll lists, predictable memory.
  • Set up the on-device testing matrix and CI for both iOS and Android builds.
  • Talk to techs in the field — most weeks you'll watch one or two using the app live.

Who you are

  • 5+ years shipping production mobile apps, ideally with React Native or Expo.
  • Comfortable in the native layer when you need to be — you've reached for Swift / Kotlin and aren't scared of it.
  • Strong opinions about mobile UX. You've used apps you respect and apps you hate and can articulate the difference.
  • Pragmatic. Native vs. cross-platform is a means, not a religion.
  • Want to be the mobile expert on a small team rather than the 30th mobile engineer at a large one.

Bonus points

  • You've shipped offline-first apps where the network really is unreliable — fishing boats, rural ag, oil & gas, anything that lives outside coverage.
  • You've worked with on-device ML or computer vision.
  • You've built something that ran on a tradesperson's truck phone, even informally.

Comp & benefits

  • $180k–$230k base depending on level and location.
  • Founding-level equity grant.
  • Health, dental, vision (we cover 100% for you, 75% for dependents).
  • Unlimited PTO with a 3-week minimum.
  • Hardware: a 16" MacBook Pro plus a current iPhone and Pixel for testing.
  • $2k/year learning + conference budget.
