Senior Android Engineer

The Senior Android Engineer is responsible for owning the end-to-end Android architecture and delivering high-performance embedded device experiences across hardware and companion applications.

• Own the full Android architecture for custom ARM-based embedded devices.
• Design and implement offline-first, modular system architecture with local data storage and future sync readiness.
• Build encrypted per-profile storage systems, local databases, and device-specific build variants.
• Integrate hardware components including cameras, sensors, lighting systems, and physical navigation controls.
• Develop shared hardware abstraction layers for device inputs, camera systems, and lifecycle management.
• Implement connectivity features such as Bluetooth audio, Wi-Fi sync, OTA updates, and device-to-device transfer.
• Design resilient systems that handle power states, cold boots, shutdowns, and constrained resources.
• Build and maintain companion mobile applications and device pairing/integration flows.
• Ensure performance optimization across boot time, camera initialization, and profile switching.
• Write clean, typed, tested Kotlin code and verify functionality directly on physical hardware.
• Conduct code reviews and establish engineering standards for Android development.
• Use AI-assisted tools to enhance productivity while maintaining strong engineering judgment.
• Plan, estimate, and deliver work within defined cycles while proactively managing risks and tradeoffs.
