Job summary

Darwoft is hiring a Senior Fullstack Engineer with a strong frontend focus to join a high-impact international FinTech project building a Customer Experience Operations Platform.

Qualifications

• 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

Responsibilities

• 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
