Inverter Design Engineer for Robotics Power Electronics

Wwshemi; 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 our actuators. You will develop motor-drive circuits and PCBs from architecture through bench bring-up and production release, collaborating with motor and embedded controls engineers to meet performance targets.

You will design power stages, sensing, and protection circuits, verify hardware with tests, and contribute to EMI/EMC and pre‑compliance work while preparing production documentation

Qualifications

• Designed and brought up a BLDC, PMSM or servo inverter on real hardware.
• Strong power-electronics fundamentals including switching devices and protection.
• Hands-on schematic and PCB experience with industry-standard EDA tools.

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 oversight, component selection and design reviews, including switching loops, grounding, isolation and thermal constraints.
• Bring up hardware with embedded controls engineers, verify switching behavior and sensing accuracy.
• Develop bench characterization for efficiency, current capability and thermal performance; apply EMI/EMC principles.
• Prepare production documentation and test requirements; collaborate with manufacturers to resolve failures and improve manufacturability.
