Android Framework Engineer
About The Position
As Flock expands our fleet of custom devices across thousands of communities, building headless operating systems that run continuously in the field requires extreme system-level reliability. Operating without standard UI components or app store frameworks means our hardware relies entirely on custom system services and low-level IPC architecture. You will engineer core system services, optimize device hardware abstractions, and build the custom Android framework powering our long-term field deployments. This isn't a mobile app development role, you won't write UI code, manage Fragments, or deploy applications to the Google Play Store. This is not a high-level application scripting job, you will spend your time in the AOSP stack writing AIDL interfaces, system services, and low-level IPC frameworks. This isn't a desktop simulation position, you will debug live code running on physical, headless camera hardware in real-world deployment states.
Requirements
- Practical experience designing versioned service interfaces using AIDL or HIDL to expose hardware functionality to system applications.
- Proficiency in Kotlin and Java with strong knowledge of OS threading concepts, coroutines, synchronization, and memory management.
- Experience building or debugging custom AOSP environments, shell scripts, init.rc configurations, and SE Linux security policies.
- Capability to trace execution flow across different layers of the Android stack using tools like Perfetto, tracing utilities, and tombstone logs.
Nice To Haves
- Experience with C or C++
- Linux kernel drivers
- Qualcomm camera stacks
Responsibilities
- Architect and implement custom Android system services, AIDL interfaces, and hardware abstractions for headless AOSP builds.
- Build testable system-level features using Kotlin, Java, Rust, and C++ to interface directly between the kernel and application layer.
- Diagnose complex OS-level memory leaks, concurrency deadlocks, and performance bottlenecks using tools like Perfetto and Android Profiler.
- Develop automated CTS and VTS test suites, unit tests, and system update pipelines to maintain fleet reliability over the air.
- Conduct root-cause analysis on system tombstones, bug reports, and kernel logs across custom Qualcomm-based hardware platforms.
