Senior Robotics Test Engineer @ Chewy

Your Opportunity Chewy Robotics is seeking a Senior Test Engineer to join our Physical AI team. This role is perfect for an engineer who thrives at the intersection of hardware and software—someone who gets excited by wires, welds, fixtures, firmware, and finely-tuned experiments. You will take full ownership of test infrastructure and instrumentation used to evaluate robotic systems. As our Lab Owner, you will lead the development of custom mechatronic testbeds, ensure the precision and repeatability of experimental systems, and collaborate cross-functionally with researchers, data scientists, and roboticists. Your work enables publication of datasets that will be used to train the next generation of physical AI models for the world’s robots. This position is based full-time onsite at the Chewy Woburn Robotics Lab. What You’ll Do Experimental Systems & Test Execution Design and implement mechanical and electrical test fixtures, instrumentation setups, and experimental workcells to replicate warehouse workflows. Plan and execute repeatable, high-quality robotics experiments, including human and robot trials, teleoperation studies, and reinforcement learning evaluations. Develop, document, and execute test procedures using structured Design of Experiments (DoE) methodologies. Hardware Design, Fabrication & Integration Own the end-to-end lifecycle of lab-built hardware: CAD design, rapid prototyping, machining, PCB bring-up, wiring, assembly, calibration, and validation. Integrate custom and off-the-shelf components into robotic systems, including sensors, actuators, cameras, force sensors, and motor controllers. Maintain safety and quality standards in lab equipment and test environments, including voltage handling, load-bearing structure assessments, and grounding verification. Lab Infrastructure & Instrumentation Maintain and improve the lab’s instrumentation backbone—motion capture (OptiTrack), LiDAR, wearable trackers, data acquisition systems, and logging pipelines. Ensure all experimental stations are instrumented for precision and reliability, with appropriate calibration, safety checks, and documentation. Manage physical lab layout and ensure optimal space usage, cable routing, and testbed modularity. Software & Systems Support Develop or extend…
