• 3+ years designing and developing power electronics, in particular, inverters for driving 50kW to 200kW motors
• Understanding of motor control theory for surface and interior permanent magnet machines
• Schematic capture and PCB design
• Experience with component selection
• Completed (designed/built/tested) high voltage/high power designs
• Great communication skills
• Ability to be onsite regularly in San Carlos, CA

Desired

• M.S./Ph.D. in relevant discipline with a focus in power electronics
• Experience working in aerospace or automotive industries
• Experience working in aerospace with a strong background in DO-160 compliance
• Experience writing embedded software in C for control of inverters and/or other power electronics
