Sr Systems Integration Engineer (HIL)

Senior Systems Integration Engineer (Hardware-in-the-Loop)We're hiring a Senior Systems Integration Engineer (Hardware-in-the-Loop) for a fast-growing autonomous vehicle and Physical AI company in San Francisco that deploys real autonomous systems in live production environments.In this role you'll build and own the hardware-in-the-loop (HIL) test benches that validate the autonomy stack off-vehicle, so every software change is proven on a reliable, production-grade bench before it reaches the fleet. This is a hands-on, lab-first role for an engineer who has built and debugged test benches for AV or robotics systems and has worked directly with lidar, radar and cameras.What You'll DoDesign, build and commission HIL test racks bringing together compute, vehicle interfaces, harnesses, wiring and sensors, from first architecture to a finished, documented benchOwn the benches end to end and keep them stable inside CI/CD; bench uptime is your key metricSimulate vehicle systems not on the bench (CAN, CAN FD, Automotive Ethernet traffic, power and drive-by-wire states) and replay recorded sensor data so on-road events become repeatable bench testsLead root-cause debugging of system-level failures across lidar, radar, cameras, sensor timing, harnessing and compute, and turn findings into design fixesContinuously improve bench tooling and automation, and write clear documentation so autonomy, embedded and vehicle teams can self-serveWhat We're Looking For4-6 years as a systems integration, HIL or test systems engineer at an autonomous vehicle or robotics companyHands-on experience building and debugging HIL / test benchesDirect experience with lidar, radar and camera sensorsVehicle networks: CAN, CAN FD, LIN, Automotive Ethernet, restbus simulation, DBC/LDFPython and C/C++; ROS / rosbag; CI/CDElectrical engineering background preferredNice To HaveGMSL / FPD-Link camera links, PTP/gPTP time syncWire harness design, schematic capture, fault injection
