Ventajas ofrecidas por este puesto de trabajo

Fully remote (LATAM)

Descripción de la vacante

Coderio is seeking a fully remote mobile developer to own an offline-first iOS/Android app from setup to public launch on App Store and Google Play. You’ll work with a small team in two-week sprints, review all diffs, add tests, and make sign-in, storage, and sync decisions with the backend developer.

You will sign accounts, set up CI, build local storage and queues, and drive conflict resolution for sync APIs. Expect heavy QA adjustements and a direct line to client communication.

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
