What you will do

• Architect and design high-power converters and inverters above 10 kW for aerospace electrical and motion-control products.
• Select power devices and design gate drives, controllers, feedback systems, magnetic components, sensing, and protection circuits.
• Define power-stage topologies, DC-bus architecture, filtering, snubbers, current sensing, safe operating envelopes, and derating.
• Drive thermal design with mechanical engineering, including heatsinks, cold plates, airflow or liquid cooling, and loss analysis.
• Own EMI/EMC strategy, grounding, shielding, PCB layout constraints, conducted and radiated mitigation, and test readiness.
• Lead schematic reviews, prototype bring-up, high-power laboratory testing, failure debugging, verification planning, test reporting, and transition to manufacturing.

Requirements

• 7+ years of power electronics design and product development experience, or equivalent depth.
• Strong experience with power converter and inverter topologies, device selection, gate-drive design, controller selection, feedback stability, protection, and high-voltage/high-current PCB design.
• Hands-on experience bringing up and debugging high-power hardware using oscilloscopes, high-voltage differential probes, current probes, power analyzers, and network or stability analyzers.
• Ability to take designs from concept through prototype, verification, and production readiness with clear documentation.
• U.S. citizenship or U.S. permanent residency is required.
• Ability to comply with applicable aerospace export-control laws and access requirements is required.

Nice to have

• Experience with high-power systems above 10 kW and aerospace qualification, configuration control, and EMI/EMC test workflows.
• Motor-drive experience with three-phase BLDC/PMSM inverters, sensing, DC-bus design, regenerative handling, and protection timing.
• High-voltage design experience in the 200–800 VDC range, including isolation and creepage/clearance.
• Experience with MIL-STD-461 or DO-160 compliance, power factor, harmonic distortion, safety qualification, ESD, lightning, and surge testing.
• Familiarity with circuit simulation tools such as LTspice, PLECS, Simetrix, Simplis, or Simulink, plus PCB CAD and layout tools.

Culture & Benefits

• Work on next-generation motion technologies for industrial, aerospace, and defense applications.
• Join a well-funded, revenue-generating company in a new hangar facility in Torrance.
• Medical insurance is fully covered by the company.
• Flexible paid time off, 401(k), and equity participation.
