Physicalintelligence Prototype Engineer at Physical Intelligence designing and fabricating mechanical, electrical, and sensor prototypes to support research and engineering development. Build end-to-end prototype systems and collaborate with researchers and engineers.

Responsibilities

Rapidly design and fabricate mechanical, electrical, and sensor prototypes to support research experiments and engineering development.
Partner directly with researchers to understand experimental requirements and translate them into buildable hardware systems.
Build end-to-end prototype systems: from concept sketches through CAD, fabrication, wiring, sensor integration, and validation.
Develop quick-turn PCBs, wiring harnesses, and cable assemblies for prototype electronics.
Evaluate and select sensors, actuators, and off-the-shelf components for integration into prototype systems.
Design and iterate on fixtures, jigs, test rigs, and custom tooling to enable research workflows.
Perform hands-on assembly, troubleshooting, and debugging of electromechanical and robotic systems.
Collaborate with electrical and robot software engineers to integrate hardware with control systems, firmware, and runtime software.
Identify and address failure modes specific to hardware operating in unstructured, real-world environments (contact forces, wear, thermal effects, cable management, etc.).
Document designs, test results, and build procedures to support knowledge transfer and design iteration.
