Job summary

Luxoft is seeking a senior Android/C++ engineer to develop and maintain Android applications and native C++ integration layers across a range of video collaboration devices. The role focuses on implementing new features, shaping architecture, and maintaining existing solutions.

You will design and extend the JNI bridge to C++20, collaborate with CV/ML researchers, and ensure robust IPC and threading across components. A strong emphasis on testing and code quality is expected.

Qualifications

• 5+ years IT experience.
• 5+ years in system or framework implementation.
• Strong Android development experience (Java and/or Kotlin).
• Experience with Android IPC mechanisms (AIDL, Messenger, ContentProvider, BroadcastReceiver, or similar).

Responsibilities

• Design, implement, and maintain Android applications (Java/Kotlin) that surface CV/ML-powered features for conference room cameras.
• Build and extend the JNI integration layer connecting Android app to C++20 native libraries with clean API boundaries and proper threading semantics.
• Collaborate with CV/ML researchers and C++ engineers to expose algorithms and pipelines to the Android layer, including debug visuals and parameter tuning interfaces.
• Design and implement IPC interfaces between the Android app and the existing app ecosystem for efficient data exchange across processes.
• Debug and optimize multithreaded, real-time video processing pipelines on Android, bridging native and managed runtimes.
• Write and maintain unit and integration tests for both Android and native layers to ensure reliability across hardware.
• Participate in code reviews and uphold engineering standards for C++ (RAII, exception-safe) and Android best practices.
