Motor Drive and Power Electronics Engineer

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

Minimum 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.

Preferred Qualifications

• Experience with high-density robot or servo drives, thermally constrained layouts and production release.
• EMI/EMC pre-compliance, fault-injection testing or functional-safety-related hardware development.
• Python-based test automation or familiarity with motor-control firmware at the hardware interface.
