Role Overview
We are looking for a talented and experienced Android AOSP Developer to join our embedded systems team. You will be responsible for building, customizing, and integrating the Android Open Source Project (AOSP) for embedded devices. This role requires deep knowledge of Android system internals, Linux kernel, HAL integration, and experience working directly with hardware platforms and BSPs.
You will collaborate with cross- functional teams, including hardware, QA, and product development, to bring fully customized Android devices to life with optimized performance and seamless hardware- software integration.
AOSP Build & System Integration
Key Responsibilities

Manage product- specific configurations, device trees, and build variants.
Port BSPs and hardware support patches across different Android versions.
Flash and validate Android builds using tools like adb, fastboot, and vendor- specific utilities.
Download, configure, build, and maintain AOSP source code for custom hardware targets.
Troubleshoot and resolve build issues across Soong, Make, Kati, and Bazel (optional)

Framework & HAL Customization

Extend and modify system services and Android framework components (e.g., SystemUI, Telephony, Connectivity).
Integrate hardware drivers and HALs (e.g., display, audio, sensors, connectivity) into the AOSP stack.
Work with AIDL/HIDL interfaces to bridge hardware abstraction and framework layers.
Optimize system performance, boot time, and reliability for production- grade devices.

Linux Kernel & Embedded Development

Analyze system performance using low- level tools (perf, ftrace, dmesg, etc.).
Customize and build Linux kernels for Android platforms, including configuration and patching.
Develop and debug kernel modules, user- space daemons, and native services in C/C++.
Manage bootloaders (e.g., U- Boot), recovery images, and root filesystem layout for embedded deployment.

Tooling & Automation

Use Linux command- line tools for system diagnostics, performance tuning, and automation.
Use repo, git, and Gerrit for source control and collaborative development.
Write scripts (Bash, Python) to automate build, flash, testing, and integration workflows.
