Job summary

Agileengine, LLC is seeking a senior mobile developer to own an offline-first iOS/Android app from project setup to launch on App Store and Google Play. You will review diffs, add tests, and decide on sync, storage, and release strategies with a backend counterpart while reporting risk and tradeoffs directly to the client team.

The role runs two-week sprints with 4–5 features, and you will work with AI coding agents daily.

Qualifications

4+ years building mobile applications, including React Native applications released on both the App Store and Google Play.
Offline-first experience with local storage, queued writes, retries and conflict handling.
Performance tuning on low-end Android devices with measurable startup time/memory.
Daily use of AI coding tools (Cursor/Claude Code) on production mobile work with CI.
Clear written and spoken English for client-facing PR descriptions, risk notes, and tradeoffs.

Responsibilities

Set up Apple and Google developer accounts, signing, CI builds and testing tracks.
Build local storage, write queue and retry logic to keep the app functional offline.
Define and agree sync and upload APIs with backend developer and resolve conflicts.
Implement phone-number sign-in with SMS codes and push notifications as a fallback to SMS.
Ensure release submissions, privacy disclosures, and crash/sync monitoring are in place.
