  • Data & State: Proficiency with TanStack Query (preferred) and lightweight state management libraries like Zustand.

  • Backend: Experience with Supabase (Realtime, Edge Functions, RLS, Storage).

  • Testing: Comfort with mobile testing (Vitest, React Testing Library) and end-to-end testing (Detox).

Preferred Qualifications

  • Advanced Platforms: Experience with EAS (Expo Application Services), React Native New Architecture (Fabric/TurboModules), and Expo Router.

  • Modern Tooling: Familiarity with tRPC, Drizzle ORM, Zod, Bun, and Monorepo tooling (Turborepo/Nx).

  • UI/UX: Experience with NativeWind/Tailwind CSS and shadcn/ui-style component primitives.

  • Domain Features: Experience with maps (clustering/location), push notifications, and background tracking.

Benefits

  • Technical Ownership: Help shape the architecture and technical direction of a growing mobile team.

  • High-Impact Work: Build tools that directly support the core operations of a large field team.
