JD -

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.

Minimum Qualifications
Strong hands-on experience with AOSP development and maintenance.
Experience working in Android OS frameworks (framework/services, system components).
Proficiency in C++.
Proficiency in Linux shell scripting (bash), including automation and troubleshooting.
Experience debugging complex issues using logs, traces, and source-level debugging.

Preferred Qualifications (optional)
Experience supporting prototype or embedded Android devices (bring-up / sustain).
Familiarity with Android build system (Soong/Make), Git workflows, and patch backporting.
Firmware exposure (boot chain, HAL-facing components, device-specific layers) is a plus.

Work Mode / Notes
This is a sustaining role: emphasis on stability, patching, and targeted backports rather than net-new feature development
