Build the mobile app that connects Senseer sensors, their users and the cloud. You will own Android and iOS end to end: hardware integration over BLE and NFC, the firmware protocol, sync, security and store releases.
// What you will do
- Build the Android and iOS apps from the ground up: architecture, UI, performance, testing and store releases.
- Connect the apps to our hardware over BLE (GATT, pairing, over-the-air firmware updates) and NFC (read, write, tag provisioning).
- Implement and maintain the firmware communication protocol: framing, retries, error handling and offline sync.
- Own mobile security: TLS certificate pinning, Android Keystore and iOS Secure Enclave key storage, encryption at rest and in transit.
- Design the local data layer (SQLite, Room or Core Data) and reliable two-way sync with the backend.
- Work with the embedded, backend, data, product and QA teams to take features from first requirement to production.
- Help shape technical and product decisions when requirements are still incomplete.
// What you bring
- 4+ years of professional mobile development.
- Production apps shipped and maintained on both Android and iOS.
- Strong native, Kotlin Multiplatform or Flutter experience, and a clear view on which fits this product.
- Hands-on BLE or NFC work with physical devices, beyond high-level libraries.
- Solid grasp of mobile security, binary protocols, networking and offline-first design.
- Experience designing local data models and syncing them with cloud services.
- Able to debug across app, connectivity, firmware and backend.
- Comfortable working from a PRD that changes: you ask the right questions, document decisions and keep moving.
You'll do well here if you
- Want to own a demanding product, not one isolated layer.
- Are comfortable testing against real hardware and chasing problems across system boundaries.
- Balance careful architecture with practical delivery.
- Communicate clearly with engineers from several disciplines.
