Fulltime

Overview:

We are seeking a Contingent Worker to support the sustaining and maintenance of Android Open-Source Project (AOSP) software (and potentially device firmware) for prototype hardware systems. This role focuses on keeping the Android build healthy and stable, integrating security patches, and backporting targeted changes from newer Android codebases as needed.

Maintain and sustain AOSP codebases for prototype systems in a sustain/maintenance mode.

Keep AOSP builds healthy, stable, and reproducible; triage and resolve build breaks.

Pull in Android security patches and ensure timely integration into the sustain branch.

Backport small-to-medium features/fixes from newer Android versions/projects into the sustain codebase based on product/engineering requests.

Debug and fix issues across the Android platform stack (frameworks and system components) and, when needed, firmware-related areas.

Write scripts and tooling to improve reliability, automation, and developer efficiency for builds and releases.

Collaborate with partner engineering teams to prioritize issues and drive fixes to completion.

Key Responsibilities:

Experience in firmware development, testing and debugging on SoCs for embedded applications.

Proficient in embedded C/C , with ability to write modular and portable code

Experience with custom hardware bring-up, using schematics and layout files

Comfortable with RTOS concepts (threads, synchronization, scheduling)

Develop and optimize low-level device drivers for peripherals and sensors (IMU, depth cameras, etc.)

Experience in bootloaders, firmware OTA update systems, and power management

Proficient in debugging tools (oscilloscope, logic analyzer, hardware debuggers)

Understanding of inter-processor communication (e.g., MCU <-> SoC)

Exposure to wireless protocols like BLE, Wi-Fi

Familiar with power profiling tools and optimizing for battery life

Understanding of firmware architecture and build systems (e.g., CMake, Makefiles)
