About This Role
An Android Developer will extend an existing Android reference application into a reliable user experience for control and audio across selectable HaLow and NR+ transports. This role is part of a project developing an Android-based communication system for sensor and control messages and audio over Wi-Fi HaLow and DECT NR+.
Responsibilities
- Maintain and extend the shared Java application; use Kotlin where appropriate to the agreed architecture
- Implement transport adapters behind a shared application interface, coordinating radio selection through the platform controller
- Support explicit network/socket binding or the selected Nordic host interface without unintended fallback
- Implement microphone capture, packetization, bounded buffering and automatic recovery after a radio transition
- Define pending-command behavior with request IDs, expiry, deduplication/reconciliation and clear status reporting
- Handle permission denial, device disconnects, activity lifecycle changes and interrupted transitions
- Add IPv6 or other transport support where required by the chosen NR+ integration
- Integrate native C/C++ transport or audio libraries through the Android NDK and JNI where needed, with clear ownership of buffers, threads and resource lifetimes
- Maintain Gradle/CMake native builds and troubleshoot native crashes, ABI compatibility and library packaging
Requirements
- 4+ years of Android development
- Java/Kotlin, Android lifecycle, permissions, concurrency and Gradle
- Hands-on Android NDK, JNI and C/C++ development, including native memory management, threading and debugging
- CMake, Gradle native integration, Clang/LLVM cross-compilation and Android ABI/shared-library packaging
- Working knowledge of GCC toolchains and GNU Make builds for existing native and embedded codebases
- Android networking, sockets and network selection
- AudioRecord, PCM data handling and resource cleanup
- State-driven UI and asynchronous error handling
- Device-level debugging using adb, logcat and network diagnostics
Nice to have:
- USB host/serial integration, IPv6 and communication with embedded accessories
- Codec integration, jitter buffering and real-time audio troubleshooting
- Experience maintaining ndk-build projects using Android.mk and Application.mk
Important Details
- Project allocation: May begin part-time during hardware feasibility; full-time during integration as host interfaces stabilize
About the Company
This company is developing an Android-based communication system for sensor and control messages and audio over Wi-Fi HaLow and DECT NR+. The project combines radio hardware, embedded firmware and Android software to support controlled radio switching and reliable recovery.
