Job summary

BairesDev seeks a seasoned mobile developer to own an offline-first iOS/Android app from setup to public release on App Store and Google Play. You’ll work with a lead and backend developer, review diffs, add tests, and decide on sync, storage, and release strategies in a two-week sprint rhythm.

You’ll implement sign-in, camera/e-signature flows, and ensure performance on low-end devices while coordinating with clients and AI coding agents in a fully remote LATAM contractor role.

Qualifications

• 4+ years building mobile applications, including React Native apps released on both App Store and Google Play.

• Clear written and spoken English for PR descriptions, risk notes and tradeoff explanations to clients.

Responsibilities

• Set up Apple and Google developer accounts, signing, CI builds and testing tracks.
• Build local storage, write queue and retry logic that keeps the app functional offline.
• Agree the sync and upload APIs with backend developer and resolve conflicts in edits.
• Develop phone-number sign-in with SMS codes and push notifications that fall back to SMS.
• Create camera capture and e-signature flows with versioned records.
• Measure and improve startup time, memory and app size on low-end Android devices.
• Handle store submissions, privacy disclosures and monitor crashes and sync.
