Job summary

Luxoft Kraków is seeking a Senior Android/C++ Developer to build and maintain Android apps and native integration layers for video collaboration devices. You will implement JNI bridges to C++20 libraries and collaborate with CV/ML researchers.

You'll design IPC interfaces, optimize real-time video pipelines on Android hardware, and write tests for both Android and native layers, following RAII and Android best practices.

Qualifications

• 5+ years IT experience.
• 5+ years experience with system or framework implementation.
• Strong experience with Android application development (Java and/or Kotlin).
• Experience with Android IPC mechanisms (AIDL, Messenger, ContentProvider, BroadcastReceiver, or similar).
• Strong experience with native C++ development (C++11 or newer).
• Hands-on experience with JNI - designing and maintaining the Java/native boundary.
• Experience with the Git version control system.

Responsibilities

• Design, implement, and maintain Android applications (Java/Kotlin) that surface CV/ML-powered features across our conference room camera product line.
• Build and extend the JNI integration layer connecting Android app logic to our C++20 native libraries, ensuring clean API boundaries, safe memory management, and correct threading semantics across the language boundary.
• Collaborate with CV/ML researchers and C++ engineers to expose new algorithms and pipeline outputs to the Android layer, including debug visualizations and parameter tuning interfaces.
• Design and implement IPC interfaces between the new Android application and the existing app ecosystem, ensuring reliable and efficient data exchange across process boundaries.
• Debug and optimize multithreaded, real-time video processing pipelines running on Android hardware, bridging native and managed runtime concerns.
• Write and maintain unit and integration tests for both the Android and native layers to ensure reliability across multiple hardware products.
• Participate in code reviews and uphold established engineering standards on both sides: modern C++ idioms (RAII, exception-safe error handling) and Android best practices (lifecycle awareness, threading, resource management).

• - Experience with Android IPC mechanisms (AIDL, Messenger, ContentProvider, BroadcastReceiver, or similar) for inter-process data exchange between Android applications
• - Strong experience with native C++ development (C++11 or newer, strictly required)
• - Hands-on experience with JNI - designing and maintaining the Java/native boundary
• - Experience with the Git version control system

Nice-to-Have Skills Description:

• - Experience developing and building projects on Linux
• - Experience creating and running projects on Docker
• - Experience with CMake for build configuration- Experience with gtest/gmock for C++ testing
• - Experience with the Conan package manager
