Android Framework Engineer

Role Overview

Join Flock Safety as an Android Framework Engineer working on embedded systems and custom hardware for AI-driven cameras. You will develop core Android system services and interfaces that enable reliable device functionality for applications.

Key Missions

• Contribute to system app and system service development, expanding usage and accessibility for engineers.
• Help build new products and next-generation device capabilities.
• Optimize code to support multiple platforms.

Responsibilities

• Develop system services and IPC interfaces.
• Design and implement hardware abstractions for device functionality.
• Create versioned service interfaces (AIDL/HIDL) to expose device capabilities to headless Kotlin/SDK applications.
• Contribute to OTA update and device reliability/self-healing.
• Perform cross-layer debugging and tracing from app code through the stack.
• Improve performance using profiling/tracing tools.
• Build testable service implementations using Rust/C++.
• Use automation and engineering best practices to raise team productivity (e.g., helper shell scripts).

Requirements

• Experience designing versioned service interfaces via AIDL/HIDL for device functionality.
• Strong Kotlin/Java development experience.
• Shell scripting experience, including init.rc familiarity.
• OTA update experience.
• System app/service development expertise (design patterns, methodologies).
• Strong debugging and tracing skills across layers of the stack.
• Knowledge of the Android build system and API design best practices between kernel and apps.
• Experience optimizing power/performance using profilers and tracing (e.g., profiler, perfetto, tracing).
• Ability to implement testable services in Rust/C++.
• Linux/Embedded exposure, including Embedded Linux and Linux kernel experience.
• Strong C/C++ skills for low-level stack components (kernel/services/bootloaders).
• Familiarity with perfetto and performance debugging.
• Familiarity with Qualcomm-based Android devices and/or Qualcomm Camera Stack.
• Exposure to security and SE Policy, and experience analyzing tombstones/bugreports.
• Familiarity with Android testing practices such as Unit tests, CTS/VTS.
• Exposure to coroutines and OS threading concepts (semaphores, synchronization, deadlocks).
• Familiarity with CI/CD and dev tools: Jira, Confluence, Jenkins, Gerrit, Git/GitHub.
• Android profiler knowledge, including memory leak/management.
• Ability to write automation shell scripts to improve productivity and share them with the team.

Nice-to-have

• AOSP development interest/experience.
• Experience with network/connectivity, reliability/self-healing, and robotics/camera-related embedded stacks.

Location / Work Mode

• Full remote.
