About the role
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.
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 STSS
Requirements
- 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 native open 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.
Preferred Skills

Experience Required

- 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
