We are seeking an experienced Android Full-Stack Engineer to join our platform stability team. In this role, you will be responsible for diagnosing, debugging, and resolving complex Android stability issues spanning the entire Android stack-both above (System Partition) and below (Vendor Partition) the Treble boundary. You will work deep within Android framework internals, reverse-engineering issues from source code, providing technical direction for ambiguous problems, and ensuring overall platform robustness across Android version upgrades. This is a hands-on engineering role for someone who thrives on solving the hardest, least-understood problems in the Android ecosystem. Key Responsibilities • Design and develop middleware and Android background services for platform-level functionality • Debug and reverse-engineer complex issues directly from Android Open Source Project (AOSP) source code Own overall Android platform stability and reliability • Resolve Android upgrade and integration issues across releases • Diagnose and fix bugs in system_server components (Activity Manager, Window Manager, Package Manager, etc.), Car Service, and SurfaceFlinger • Investigate and resolve black screen, boot failure, and ANR (Application Not Responding) issues • Resolve and provide technical direction and root-cause analysis for unknown or hard-to-reproduce issues • Address and resolve compliance test failures across CTS, VTS, ATS, and STS Job Requirements Skills Required: • Kotlin, C++, Java • Kotlin - Candidate should be able to write and maintain Kotlin-based Android background services and middleware components and be comfortable working within Kotlin code in the Android framework/system_server layer (e.g., modifying or extending services like Activity Manager, Package Manager) as part of resolving platform stability issues. • C++ - Candidate should have hands-on experience debugging and modifying native Android components (e.g., SurfaceFlinger, HAL layers, vendor partition code) in C++, including reverse-engineering issues directly from AOSP nativeopen source code. • Java - Candidate should be able to read, debug, and modify Java-based Android framework code (system_server internals such as Window Manager, Activity Manager) to diagnose and resolve issues like ANRs, boot failures, and black screens, including designing AIDL/Binder interfaces exposed to applications. Experience Required • 3+ years of hands-on Android platform/framework development experience. • Proven experience in designing and developing middleware and Android background services (long-running/foreground service) that expose feature-rich interfaces (AIDL/Binder, APIs) to applications. • Demonstrated track record of resolving complex, low-level Android stability issues. • Experience contributing to or modifying AOSP source code • Proven experience working across the full Android stack (framework, native services, vendor layers) Experience Preferred • Experience with Android Automotive OS (AAOS) and Car Service. • Familiarity with HAL (Hardware Abstraction Layer) and vendor integration. • Experience with CTS, VTS, ATS, and STS compliance frameworks. • Knowledge of Android graphics stack and display subsystems. • Experience with native debugging tools (gdb, lldb, perfetto, systrace, logcat analysis). • Familiarity with Android build systems (Soong/Make) and partition architecture. • Experience working with SoC/silicon vendors on platform bring-up Education Required • Bachelor's Degree Education Preferred • Master's Degree **Listed salary ranges may vary based on experience, qualifications, and local market.
