Descripción de la vacante

Tether is hiring a Mobile Engineer to own Keet Mobile end-to-end, from UI to P2P core integration, for iOS and Android. You will drive features in a React Native/Expo stack, ensure offline reliability, and coordinate with a back-end teammate on sync solutions.

This is a 100% remote role with US-hour overlap and a commitment to quality through tests and CI. Join a fast-moving fintech team pushing global, borderless digital finance.

Formación

• 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 Cursor, Claude Code or a similar AI coding tool 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.

Responsabilidades

• Set up Apple and Google developer accounts, signing, CI builds and testing tracks.
• Build the local storage, write queue and retry logic that keep the app working offline.
• Agree the sync and upload APIs with the backend developer, and decide how conflicting edits resolve.
• Build phone-number sign-in with SMS codes, and push notifications that fall back to SMS.
• Build camera capture and e-signature flows that save each signed record as a new version.
• Measure and improve startup time, memory and app size on low-end Android phones.
• Handle store submissions, privacy disclosures and review rejections, and add crash and sync monitoring.
