Motor Drive & Power Electronics Engineer — Robotics Inverter

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

Job summary

Dexmate Inc. 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.

You will work closely with motor and embedded controls engineers to ensure electrical limits, sensing and protection meet the actuator’s performance requirements. As part of a collaborative hardware team, you will contribute to design reviews, bench characterization

Qualifications

• Designed and brought up a BLDC, PMSM or servo inverter on real hardware.
• Strong power-electronics fundamentals: switching devices, gate drive, current sensing, protection.
• Hands-on schematic and PCB experience with industry-standard EDA tools.
• Knowledge of field-oriented control and co-design with firmware engineers.

Responsibilities

• Define inverter architecture and electrical operating limits with the actuator lead.
• Design power stages, gate drivers, DC-link components, current and voltage sensing, encoder interfaces and protection.
• Own schematics, PCB layout or layout oversight, component selection and design reviews.
• 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.
