Mobile Developer, React Native

This is a fully remote position, open to applicants in Latin America.

📋 Description

• Establish Apple and Google developer accounts, including signing, continuous integration builds, and testing tracks.

• Develop the local storage, write queue, and retry logic to ensure the app functions offline.

• Collaborate with the backend developer to agree on sync and upload APIs, determining how to resolve conflicting edits.

• Create phone-number sign-in functionality with SMS codes and implement push notifications that revert to SMS when necessary.

• Design camera capture and e-signature processes that save each signed record as a new version.

• Analyze and enhance startup time, memory usage, and app size on low-end Android devices.

• Manage store submissions, privacy disclosures, and address review rejections.

• Implement crash and sync monitoring.

• Operate as the sole mobile developer from the initial project setup through to the public launch on the App Store and Google Play.

• Review code diffs generated by AI, add any missing tests, and communicate risk notes and tradeoffs to the client team.

⛳️ Requirements

• Minimum of 4 years of experience in developing mobile applications, including React Native apps launched on both the App Store and Google Play.

• Experience with offline-first development, including local storage, queued writes, retries, and conflict resolution.

• Proven performance optimization on low-end Android devices, with metrics on startup time or memory usage recorded pre- and post-changes.

• Regular use of Cursor, Claude Code, or similar AI coding tools in production mobile projects, alongside TypeScript, automated testing, and continuous integration.

• Proficient in written and verbal English for creating PR descriptions, risk assessments, and explaining tradeoffs to the client team.

• Background in working from written acceptance criteria and the ability to challenge merges that do not meet those criteria.

🏝️ Benefits

• Fully remote contractor position based in LATAM, requiring approximately 40 hours of work each week.

• Core working hours aligned with US time zones, ensuring overlap with the lead developer and backend developer.

• Ownership of a single app from the initial project stages through to its public release on both app stores.

• Authority over sync, storage, and release decisions, collaborating closely with a backend developer.

• A team environment where AI coding agents are integrated into daily workflows, supported by typed code, automated tests, and continuous integration.
