Job Description :

We are looking for a Native Android Developer to build and maintain mobile applications for a connected-device platform. The app is an always-online solution that relies on the cloud for permission validation and access generation, while interacting with hardware over Bluetooth (BLE) and supporting NFC/RFID credentials. You will own feature development, maintenance, and production support, working closely with Cloud, Firmware, DevOps, and QA teams to deliver releases on time.

Key Responsibilities :

- Native Android development using Kotlin and the Android SDK

- Write unit and UI tests to minimize defects and reproduce intermittent issues

- Troubleshoot and provide fast-turnaround hotfixes for production issues

- Conduct code reviews and maintain technical documentation

- Collaborate closely with the Cloud/Web team on API integration

Required Skills & Experience :

- Expert-level native Android development (Kotlin, Android SDK)

- Strong experience with RESTful and GraphQL API integration

- Mobile-specific security : certificate pinning, secure credential storage, token-based auth (JWT, Cognito or similar)

- Hands-on BLE experience (Nordic BLE or equivalent); familiarity with encrypted device communication

- Strong understanding of mobile UI/UX patterns and Material Design guidelines

- Experience with CI/CD pipelines for mobile applications

- Testing frameworks : JUnit, Espresso, Kaspresso

Preferred / Nice to Have :

- Experience with IoT / connected-device companion apps (strongly preferred)

- Experience with OTA firmware update flows

- Exposure to NFC/RFID credential encoding
