Perception Engineer

Sauron is a home operating system focused on secure, private residential perimeter security through an autonomous platform and 24/7 command center. The Staff Perception Engineer will own the architecture, quality, and technical direction of sensing and perception systems that detect, classify, and track people, vehicles, and threats in real-world conditions. The role includes developing algorithms and data pipelines, optimizing edge inference, integrating with hardware and software teams, and leading perception-focused technical work.

Responsibilities:

• Evolving the pipeline architecture so cameras can come and go, and configuration can change, without disrupting live video or losing object identity
• Setting the boundary between systems and models. You decide what belongs in the compiled service, what belongs in the inference graph, and where the performance ceiling really is
• Owning perception quality end to end. Defining what good looks like in numbers: evaluation data, a regression harness, and a defensible story on model choice for our hardware
• Extracting the maximum value from our sensors. Fusing every observation available while staying robust to occlusion, poor lighting, and deliberate evasion
• Taking the service from "runs" to "trustworthy unattended." Failure detection, graceful degradation, and observability good enough that we know why something broke without a site visit
• Closing the loop from the field. Using deployment data to find headroom, and building the dataset and evaluation infrastructure that makes that repeatable
• Leading the work and the people. Setting direction across perception, reviewing the hard changes, and owning the interfaces perception exposes to the rest of the product
