Mind Robotics is building Physical AI for real-world industrial deployment, starting with the factory floor. The company believes the hardest problems in AI are solved when researchers and engineers are hands-on with the physical world every day.
As the Power Electronics Engineer, you will own the robot's power architecture end to end—from how power reaches every compute, sensing, and actuation load to the motor inverters that drive each joint. Your decisions shape the entire robot program, not just your own boards. The compute, actuation, controls, and systems teams build against the specs you set, and their schedules depend on your delivery.
Key responsibilities include:
- Own the complete power architecture, from distribution across compute, actuation, sensing, and peripherals to motor inverters. Set rail budgets and interfaces that other teams depend on.
- Decide power system priorities and defend tradeoffs against power density, thermal, cost, and reliability targets.
- Make strategic domain calls on topology, Si/GaN/SiC device technology, make-vs.-buy decisions, and supplier strategy. Commit power specs and dates to the program.
- Set power design standards adopted by other hardware teams, covering derating, layout, EMI, protection, and validation. Lead cross-team design reviews and mentor engineers.
- Stay hands-on with distribution networks, inverter stages with discrete gate drivers, DC-DC conversion, current sensing, and protection circuits.
- Deliver high power density within tight thermal limits, from PCB design through bring-up, validation, and fault injection testing.
- Own the power side of firmware and telemetry interfaces (EtherCAT, PMBus, I2C, SPI), connectors, and pinouts.
- Manage fabricators and suppliers for delivery, design-for-manufacturing (DFM), and second sourcing.
REQUIREMENTS:
- Degree in Electrical Engineering or equivalent experience.
- Proven track record owning a product's power architecture (not just individual boards) that other teams built against.
- Deep expertise in either power distribution or inverter power stages, with architecture decisions spanning both domains.
- Strong DC-DC design skills, including topology, magnetics, and loop compensation, plus current sensing and protection circuits.
- Strong high-current layout, EMI/EMC, bring-up, and measurement skills, including double-pulse testing and gate-drive characterization.
- Experience with harnesses, connectors, volume manufacturing, and contract manufacturers.
- Demonstrated ability to set design standards adopted beyond your own team.
- Strong pluses: EtherCAT and GaN/SiC experience.
