Descrizione del lavoro

Tether is seeking a Mobile Engineer (React Native) to own Keet Mobile end-to-end from initial project setup to public release on iOS and Android. You will work 100% remotely from LATAM, collaborating with a lead and backend developer to design sync, storage, and release strategies, and to ensure robust offline functionality.

You will review diffs, write tests, monitor performance, and handle store submissions and crash/sync monitoring.

Competenze

• 4+ years building mobile applications, including React Native applications released on both the App Store and Google Play.
• Offline-first work you built yourself: local storage, queued writes, retries and conflict handling.
• Performance tuning on low-end Android, with startup time or memory measured before and after a change.
• Daily use of AI coding tools on production mobile work, with TypeScript, automated tests and CI around it.
• Clear written and spoken English for PR descriptions, risk notes and tradeoff explanations to a client team.
• Experience working from written acceptance criteria, and the judgment to push back on a merge that misses them.

Mansioni

• Build and polish features across chat, voice and video calls, media sharing, device pairing and identity backup.
• Integrate native platform capabilities such as push notifications, camera, bio-metrics and background tasks on both iOS and Android.
• Profile and optimise performance on real devices, including startup time, long chats, media handling, battery and network use.
• Write unit and end-to-end tests, and help keep releases stable through CI and crash reporting.
• Work closely with the core P2P, design and product teams, and review code with a high bar for quality.
