Skills: Python
ABOUT DEXMATE Dexmate is building the foundation for physical AI — combining a new generation of robots with a universal Physical AI OS, making robots as easy to build and deploy as software. Today, robotics is fragmented, slow, and closed: most builders are forced to reinvent the same stack again and again, and most ideas never make it past the prototype stage. We exist to change that. Our mission is to democratize robotics by lowering the barrier to entry, delivering a plug-and-play platform for developers, researchers, and enterprises, and cultivating an open ecosystem that accelerates the evolution of physical AI. If you want to help shape the next layer of human capability — and believe the future of robotics should be built together, not in isolation — we'd love to build it with you. THE ROLE We are looking for a Motor Drive and Power Electronics Engineer to own the inverter hardware that powers Dexmate actuators. You will develop motor-drive circuits and PCBs from architecture through bench bring-up and production release. You will work closely with motor and embedded controls engineers so electrical limits, sensing and protection support the actuator’s required performance. RESPONSIBILITIES - Define inverter architecture and electrical operating limits with the actuator lead, motor designer and robot power-system team. - Design power stages, gate drivers, DC-link components, current and voltage sensing, encoder interfaces and hardware protection circuits. - Own schematics, PCB layout or layout oversight, component selection and design reviews, including switching loops, grounding, isolation where needed and thermal constraints. - Bring up hardware with embedded controls engineers; verify switching behavior, sensing accuracy, losses and safe responses to electrical faults. - Develop bench characterization for efficiency, current capability and thermal performance; apply EMI/EMC principles and support pre-compliance testing. - Prepare production documentation…
