• Strong experience with multi-module Android architecture.

• Strong knowledge of Android lifecycle, threading, memory management, and application performance.

• Hands-on experience with Camera2 API.

• Hands-on experience consuming JNI/native libraries within Android applications.

• Experience debugging native crashes and Android application integration issues.

• Experience deploying applications to physical Android devices and hardware.

• Experience with Gradle, Git, profiling, and Android Studio.

• Experience working with hardware or sensor-driven applications is preferred.

• Experience mentoring junior Android engineers is preferred.

• Experience in medical devices, navigation, robotics, computer vision, AR/VR/XR, or high-availability software will be an added advantage.

Skills and Competencies :

• Strong proficiency in Java and Kotlin.

• Strong knowledge of Android application architecture and multi-module design.

• Strong proficiency in Android Studio and Gradle.

• Strong understanding of Android lifecycle and component management.

• Strong knowledge of Camera2 API and camera lifecycle management.

• Strong understanding of multithreading, concurrency, synchronization, and background processing.

• Strong understanding of memory management and performance optimization on constrained devices.

• Good knowledge of JNI/NDK and native library integration.

• Experience debugging native crashes, ANRs, memory leaks, and application freezes.

• Experience with Git and structured branching/release practices.

• Experience with Android profiling and performance analysis tools.

• Understanding of real-time data processing and UI update patterns.

• Experience with sensor-driven or hardware-key-based user interfaces.

• Experience with OpenCV Android integration is preferred.

• Experience with OpenGL or AR overlay rendering is preferred.

• Understanding of kiosk, home-launcher, device-owner, or enterprise-managed Android deployment patterns is preferred.

• Strong debugging and root-cause analysis capabilities.

• Strong attention to application stability, reliability, performance, and usability.

• Strong communication and collaboration skills.

• Ability to work effectively with software, hardware, computer vision, algorithms, QA, systems, and clinical teams.

• Ability to work with physical devices and laboratory navigation systems rather than emulator-only environments.

• Passion for Android engineering, wearable computing, surgical robotics, immersive technologies, and healthcare innovation.

Key Performance Indicators :
