• Customize and maintain our proprietary AOSP fork. • Collaborate with ODMs/manufacturers to integrate and validate their AOSP patches, Board Support Packages (BSP), and Hardware Abstraction Layers (HAL). • Design and implement features that require a deep understanding of Android internals (e.g., PackageManager, ActivityManager, WindowManager). • Implement and debug complex inter-process communication using AIDL/Binder interfaces. • Develop and debug the Linux kernel and device drivers for our custom hardware. • Perform low-level device debugging (e.g., using UART, JTAG). • Implement and maintain robust OTA (Over-the-Air) system image update workflows. • Conduct system performance profiling and optimization (e.g., using systrace, perfetto) across the entire software stack, from kernel to SDKs. • Collaborate closely with product management, hardware, and other engineering teams on technical requirements and seamless hardware/software integration. • Create and maintain detailed documentation related to AOSP and low-level system development. • Assist in project management for AOSP development, ensuring timely delivery. • Provide technical support for system-level and AOSP-related issues internally and externally. • Stay updated with the latest trends and best practices in AOSP and Android platform engineering. • Communicate regularly and clearly with stakeholders about progress and challenges.
