Descripción de la vacante

Werben HR LLC is seeking a remote mobile developer to own an offline-first iOS/Android app from setup to public launch on App Store and Google Play. You’ll build the local storage, write queue, and retry logic that keeps the app functional offline, and you’ll define sync and upload APIs with the backend.

You’ll report to studio leadership, collaborate with the lead and backend developers, and write risk notes directly to the client with your recommendations.

Formación

• 4+ years building mobile applications, including React Native apps released on both stores.
• Offline-first experience with local storage, queued writes and retry logic.
• Performance tuning on low-end Android devices with measurable results.
• Daily use of AI coding tools in production work, with TypeScript, automated tests and CI.
• Clear written and spoken English for client communications and risk notes.
• Ability to work from written acceptance criteria and push back when needed.

Responsabilidades

• Set up Apple and Google developer accounts, signing, CI builds and testing tracks.
• Build local storage, write queue and retry logic for offline operation.
• Agree sync and upload APIs with backend, and resolve conflicting edits.
• Implement phone-number sign-in with SMS codes and fallback push notifications.
• Build camera capture and e-signature flows storing versioned records.
• Measure startup time, memory and app size on low-end Android devices.
• Handle store submissions, privacy disclosures and monitor crashes/sync.
