Android Framework Engineer

Every community deserves to be safe, it’s a fundamental right. Our mission is simple - to build technology that reduces crime and protects privacy. Flock partners with cities, businesses, schools, and neighborhoods to help protect where people live, work, and play. Last year, Flock technology supported over 1 million criminal investigations. We've also helped solve approximately 20% of reported crimes in areas where we're deployed, and have played a role in locating more than 10,000 missing people.

We are a high-performance team united by urgency, ownership, and a shared commitment to meaningful impact. The work is fast-paced and the expectations are high. We push beyond perceived limits, support each other, and hold ourselves accountable to delivering results that matter.

With over $1B in funding and an $8.3B valuation, we are scaling with intention and investing in the people who will help us build what others said could not be done. At Flock, you will find the opportunity to grow quickly, take on real responsibility, and contribute to something bigger than yourself.

Flock Safety is looking for an Android Framework Engineer to join our Device OS Team. To be clear: this is an Embedded Systems role, not a Mobile App role. We build on headless, custom AOSP builds—meaning there are no UI components, no Fragments, and no Play Store. You will be responsible for the "guts" of the device, developing the system services, IPC interfaces (AIDL), and hardware abstractions that allow our AI-driven cameras to capture and process data autonomously in the field for years. If you enjoy working at the intersection of the Android OS and custom hardware, this is your playground.

We are looking for people who:

• Bring experience designing versioned service interfaces via AIDL/HIDL to expose device functionality to headless Kotlin apps via a custom SDK

• Have developed testable service implementations in Rust/C++

• Bring knowledge of the android build system and best practices for API design between kernel and apps

• Have strong Kotlin/JAVA development experience such as but not limited to

  • Exposure to coroutines & OS threading concepts such as semaphores, synchronization, deadlocks

  • familiar with android profiler & memory leaks/management, etc.

  • Unit testing, CTS/VTS.

  • Power and performance optimizations, profiler, perfetto, tracing

• Have exposure to or interest in AOSP development:

  • Including shell scripting experience & init.rc

  • Exposure to security and SE Policy

  • Possess strong debugging skills on custom Android HW.

  • Ability to trace app code through different layers of the stack

  • OTA update experience

  • Reliability / self-healing

  • Network / connectivity

  • Tombstone / bugreport analysis

• System app development, methodologies, design patterns, etc.

• Have experience with architecture, design, and documentation.

• Skilled in JIRA, Confluence, Jenkins, Gerrit, Git/GitHub.

Nice to Haves:

• C/C++ skills and expertise with lower levels of the stack such as kernel, services, bootloaders etc.

• Linux kernel driver development experience

• Experience working on Linux platforms, including Embedded Linux

• Familiarity with tools like perfetto used for debugging and performance

• Familiarity with Qualcomm based Android devices

• Experience with Qualcomm Camera Stack

• Have the ability to write automation shell scripts to improve self productivity and share such helper scripts with the team to boost overall productivity.
