Job Location: Bangalore, the mode of interview will be in-person Role Summary We are seeking a Mobile Developer (iOS/Swift or Android/Kotlin, or Cross-Platform Flutter/React Native with Native Modules) to build our companion wearable app. You will own the connection between the OEM hardware device and our mobile app, leveraging a vendor SDK to ensure seamless, passive Bluetooth Low Energy (BLE) background data syncing and constructing responsive health dashboards. Cross-platform mobile: Flutter or React Native — 3+ years, with at least 2 apps shipped to both the App Store and Google Play. need links and verify the apps exist. Native module/bridge experience — they must have written Flutter platform channels or React Native native modules before. Native language literacy — comfortable reading/writing Swift and Kotlin , Bluetooth Low Energy (BLE) — experience with BLE devices (wearables, fitness devices, IoT). Knows about connection lifecycle, background reconnection, platform-specific BLE quirks. Local data + sync — SQLite/Room/Drift, handling offline-first data, time-series health data storage. Strongly preferred: 6. Wearables/health app background — has worked with fitness trackers, smartwatches, or health devices; familiarity with HealthKit (iOS) and Health Connect (Android) so your app can integrate with the phone's health ecosystem. 7. Background execution knowledge — iOS background modes, Android foreground services and battery-optimization workarounds (this is where health-device apps commonly fail). 8. Charting/data visualization — health apps live and die on their graphs. 9. AI-assisted workflow fluency — already uses Claude Code/Cursor/Copilot daily and can describe how (not just "yes I use AI"). Ask: "Walk me through how you used AI on your last project and where you didn't trust it." Nice-to-have: 10. Backend basics (Firebase/Supabase or simple REST API) if you'll want cloud sync and accounts later. 11. App store release experience — provisioning profiles, TestFlight, Play Console, review-rejection handling. 12. Awareness of health-data privacy (HIPAA/GDPR basics, Apple's health data rules) — Apple reviews health apps more strictly than average.
