Homeowners today lack compelling options when it comes to peace of mind against vulnerabilities, and total command and control of their home; there is no definitive, protective brand in the space. Leveraging cutting-edge AI, sensor technology, and nonlethal deterrence, Sauron brings next-generation technology to homeowners to protect their families and property. Incubated by the serial entrepreneur Kevin Hartz and Atomic, Sauron has raised an $18M seed round from leading venture capital firms and angel investors, including 8VC and Flock Safety CEO Garret Langley, to build the new perception system for the home. ### The Role - Senior Perception Engineer Perception is the foundation of the Sauron product. Every decision the system makes (what to show a homeowner, what to disregard, what to escalate) depends on whether we have correctly understood what took place outside the home. We are seeking the person who will own this domain. Our hardware operates around the home and must complete its mission reliably in all environmental conditions: at night, in adverse weather, and in the presence of occlusion and deliberate evasion. In this role, you will set the technical direction for how we achieve that, including what we sense, what we infer, which problems are best addressed through models and which through systems, and what "ready to ship" means in measurable terms rather than impressions. You will own the perception architecture and the accuracy, latency, and cost tradeoffs that underpin it. You will work closely with the hardware team to define sensing requirements across successive product generations, and you will serve as the authority that cloud, product, and hardware teams consult to understand what perception can and cannot do. You will write a substantial amount of code, focused on the most difficult problems, but your success will be measured by whether the perception system as a whole becomes better, faster, and more trustworthy. ### We Value Collaboration, pair programming, and teamwork. Taking ownership across the stack. Test-driven development, and refactoring regularly to keep our codebases healthy. ### You Will Contribute By... 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. ### Your Background Includes... Around 5+ years building production systems, with several at staff scope: owning a system's architecture, not just its tickets. Significant professional experience with perception or machine learning for hardware products in a safety-critical field - aerospace, robotics, medical devices, autonomous vehicles, or physical security. Deep modern C++. This is a C++20 codebase with Abseil, gRPC, and CMake; you should be comfortable owning lifetime, threading, and shutdown semantics in a long-running daemon. Real GStreamer or media-pipeline experience, DeepStream or another NVIDIA video stack: pads, probes, caps negotiation, bus messages, and the specific pathology of a pipeline that is alive but not moving. --- Data: alder (https://alderhq.app).
