Job description

The Role

Sauron is creating a new modality for homeowners to interact with their properties and security systems—anchored by a high‑fidelity 3D model of the home in a beautiful iPad and iPhone app, and powered by intelligent devices at the edge. We’re looking for a highly technical, thoughtful, and collaborative Lead Device Software Engineer to build the platform that connects on‑prem devices, edge compute, and cloud services into a cohesive, safe, and reliable system. This is a senior, hands‑on position.

What You Will Do

• Develop from scratch and maintain embedded Linux platforms, from BSP to application level.
• Work with electrical, mechanical, perception/ML, backend, and mobile teams to define architectures for new on‑device software.
• Build and maintain embedded software that interface with sensors, cameras, and motors.
• Drive features end‑to‑end through the full software lifecycle: design, implementation, validation, and production rollout.
• Build and improve embedded build systems, CI/CD, and automated test environments; plan and execute test procedures across unit, HIL, and on‑device validation.
• Root‑cause and resolve issues using remote fleet diagnostics, telemetry, and local hardware test platforms; define logging and observability standards.

Who You Are

• 8+ years of professional experience developing device software for hardware products with experience shipping multiple consumer products end to end.
• Experience with Linux on embedded/constrained systems, such as Yocto or AOSP.
• Experience writing C/C++ for Linux, FreeRTOS, and bare‑metal systems.
• Demonstrated ability to write multi‑threaded, highly reliable code.
• Strong grasp of software lifecycle best practices: code reviews, version control, unit/integration testing, CI, and on‑hardware validation.
• Understanding of the manufacturing process, including device testing, validation, calibration and fusing.

Nice to Have

• Ideally been a past team lead or manager
• Experience building custom embedded Linux distributions with Yocto
• Experience with ARM Trustzone, and OP-TEE
• Experience with FreeRTOS
• Background contributing to or growing high‑performance software teams.
