Power Electronics Electrical Engineer II

About the role

Shield AI is building its next-generation aircraft, XBAT, and is looking for a Power Electronics Electrical Engineer II to contribute to the design, analysis and validation of power electronics systems critical to the aircraft. The role suits an engineer with a solid foundation in power systems who wants to own challenging projects and see their work move quickly from concept to flight.

Key responsibilities

• Design high-voltage and low-voltage power systems, including DC-DC converters, inverters and motor controllers, battery management, power generation and distribution, and embedded safety and protection mechanisms.
• Engineer solutions across power ranges, from less than 1 kW low-power systems to more than 10 kW high-power applications.
• Own the full cycle of hardware development: concept, modeling, worst-case analysis, schematic capture, simulation, prototyping, design iteration, testing and validation.
• Drive PCB layout and design with ECAD engineers, optimizing for power density, EMI, thermal performance and manufacturability.
• Execute board bring-up, verification, validation and HALT testing to meet aerospace reliability standards.
• Work with Mechanical, CAD, Embedded, Software, Production and aircraft teams, and lead cross-functional design reviews.
• Manage project timelines, deliverables and technical milestones.

Required profile

• B.S. in Electrical Engineering or equivalent.
• At least 1 year of experience as an electrical engineer.
• Experience with circuit design, schematic capture, component selection, circuit testing and debugging.
• Familiarity with Altium or equivalent.
• Experience with lab equipment such as oscilloscopes, power supplies, E-loads and multimeters.
• Ability to obtain a S//SAR level security clearance is desired.
