Requirements:

• 5+ years of software development experience, with 3+ years dedicated to in-depth React Native for cross-platform mobile apps.
• Expert proficiency in React Native core principles, Expo (including EAS), TypeScript, and modern state management (e.g., Jotai, Zustand, Redux).
• Proven experience in profiling and optimizing complex mobile applications (e.g., using React Profiler, Flipper) and resolving common performance bottlenecks (rendering, memory, bridge).
• Deep experience architecting and building Design Systems with a focus on modularity, scalability, and performance.
• Extensive experience designing and managing the network/data fetching layer , including advanced use of state management for server data (e.g., Tanstack Query, SWR, or Apollo), optimistic UI updates, and implementing robust retry/caching logic
• Strong product sense, championing user-centric design to deliver the simplest, most intuitive experience.
• Proficiency in backend integrations (REST API) and experience with cloud platforms (Firebase, Supabase, and/or GCP).

Bonus Points:

• Successful app launches on the App Store and Google Play.
• Experience with native development (Swift/Kotlin) or mobile testing frameworks (Jest, React Native Testing Library).
• Familiarity with CI/CD processes and JSI libraries (e.g., Reanimated v2+)

Why Join Us?

• Impact: You will shape the product, architecture, and engineering culture from day one.
• Frontier: Work at the cutting edge, utilizing and implementing the newest AI tools (Claude Code, Gemini, etc.) into your daily workflow, top-tier equipment (M4 Macbook Pro)
