Who We Are

Sauron protects your family and home, bringing the innovations of autonomous robots and self-driving cars to residential security. Our team is led by veteran operators and engineers, alumni of Sonos, Paypal, Tesla, Apple, and Google. Sauron has raised an $27M seed round led by A* and Atomic with participation from other leading venture capital firms.

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.

We Value

1. The Power of "We": “Align, then Accelerate”

• We celebrate as a team and troubleshoot as a team.
• The goal is the mission, not the credit.

2. High Challenge, Low Ego: "Respect the person, debate the idea."

• Be ruthless with problems, but kind to people.
• Raise the bar, lower the shield

3. Speak up: "Silence is a setback."

• Your perspective is a requirement, not a suggestion.
• Speak the hard truths early so we can fix them fast.

4. Integrity in Motion: "Own the outcome, not just the task."

• Do what you say you’ll do.
• If it breaks, fix it. If it works, make it better.

5. Humanity at the Core: "Relationships over transactions."

• Earn trust through empathy and consistency.
• Anticipate needs before they become requests.

The compensation range for this position is $210-250k base + equity + benefits.

We are focused on building a diverse and inclusive workforce. If you’re excited about this role, but do not meet 100% of the qualifications listed above, we encourage you to apply.
