Résumé du poste

Alpha Efficiency seeks a seasoned mobile developer to own an offline-first React Native app from initial project setup through App Store and Google Play launches. You will collaborate with a small team, review changes, add tests, and make critical decisions on sync, storage, and releases for a smooth, scalable product.

You’ll work with a backend counterpart on APIs, report directly to leadership, and communicate risks and tradeoffs to the client team.

• 4+ years building mobile applications, including React Native apps released on App Store and Google Play.
• Offline-first work with local storage, queued writes, retries and conflict handling.
• Performance tuning on low-end Android devices, tracking startup time/memory changes.
• Daily use of AI coding tools (Cursor/Claude Code) with TypeScript, automated tests and CI.
• Clear written/spoken English for PR descriptions, risk notes and tradeoff explanations to clients.
• Experience working from written acceptance criteria and pushing back on merges that miss them.

Responsabilités

• Set up dev accounts, signing, CI builds and testing tracks.
• Build local storage, write queue and retry logic for offline operation.
• Define sync/upload APIs with backend dev and resolve conflicts.
• Implement phone-number sign-in with SMS codes and push notifications fallback.
