Your focus will be on ensuring system stability, peak performance, and strict compliance with global industry standards.

Key Responsibilities

Core Platform Development

• Hardware Interfacing: Build and maintain a robust foundation in C/C++ to develop hardware drivers and Hardware Abstraction Layers (HAL).
• System Services: Design and optimize system-level services that interact directly with the Linux kernel.
• AOSP Management: Compile, customize, and manage Android Open Source Project (AOSP) source code to meet specific platform requirements.
• Modern Language Support: Leverage Java and Kotlin (Android's recommended language) for high-level system integration.

Daily Maintenance & Build Engineering

• Source Control: Manage complex codebases using Git and Repo, handling advanced branching, merging, and rebasing across multiple repositories.
• Build Systems: Utilize Make and Soong to manage and optimize build configurations across diverse hardware platforms.
• Troubleshooting: Rapidly diagnose and resolve compilation errors across varied hardware and software environments.

Quality Assurance & Performance

• Sanity Testing: Automate and perform sanity tests to ensure core functions (boot-up, essential apps, and communication) remain stable after every update.
• Compliance: Set up and execute CTS (Compatibility Test Suite) and VTS (Vendor Test Suite) to ensure the platform meets official Android standards.
• Deep Debugging: Use ADB, systrace, and logcat to resolve system-level performance bottlenecks and complex bugs.

• Tooling: Expertise in Git, Repo, and debugging tools (ADB, systrace, logcat).
• Build Systems: Direct experience with Make and Soong.
• Communication: Intermediate English proficiency (capable of technical reading, writing, and participating in international team calls).
• Problem Solving: Strong analytical skills with a focus on source code analysis to resolve complex issues.

Preferred Qualifications

• Customization: Experience integrating Android builds for specific, non-standard hardware platforms.
• Communication Protocols: Knowledge of JNI, AIDL, and deep Android framework customization.
• Automation: Familiarity with CI/CD workflows for automated testing and builds.
• Global Experience: Prior experience working within cross-functional, international engineering teams.
