Robotics Motor Drive & Power Electronics Engineer

Dexmate; Fremont (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Dexmate is seeking a Motor Drive and Power Electronics Engineer to own the inverter hardware powering 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 to ensure electrical limits, sensing and protection meet performance requirements. The role emphasizes hands-on hardware design, rapid prototyping, test, and collaboration with manufacturing to improve

Qualifications

• Designed and brought up a BLDC, PMSM or servo inverter or motor-drive product on real hardware.
• Strong power-electronics fundamentals, including switching devices, gate drive, current measurement, PCB layout and protection.
• Hands-on schematic and PCB experience with an industry-standard EDA tool, and strong oscilloscope, current-probe and power-analysis skills.
• Working knowledge of field-oriented control and motor characteristics sufficient to co-design hardware and debug with firmware engineers.

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 and test requirements; work with manufacturers and electrical test engineers to resolve failures and improve manufacturability.
