Senior Power Electronics Engineer

Role Summary

We are hiring a Senior Power Electronics Engineer to lead the design and integration of high-power (>10 kW) power conversion hardware for aerospace electrical and motion control products. You will own key power-stage architecture decisions, drive prototype bring-up and verification, and partner with controls, firmware, mechanical, and manufacturing teams to deliver flight- and mission-ready hardware.

What you'll do

• Architect and design high-power converters/inverters (>10 kW) for aerospace electrical and motion control products, balancing efficiency, power density, and reliability
• Select and apply Si, SiC, and/or GaN power devices (as appropriate) and design gate-drive, controller, feedback stability, magnetic components including power inductors and transformers, sensing, and protection (short-circuit, overcurrent, over/undervoltage, thermal, desaturation)
• Design topologies and the power stage (DC bus, precharge/discharge, snubbers/clamps, current sensing, filtering) and define safe operating envelopes and derating at given environments
• Drive thermal design with mechanical engineering (heatsinks, cold plates, airflow/liquid cooling) and validate junction-to-ambient performance including loss breakdown, thermal analysis
• Own EMI/EMC strategy for aerospace environments: grounding, shielding, layout constraints, conducted/radiated mitigation, filter design, and test readiness
• Lead schematic capture and review PCB layout for low-inductance, high-current/high-voltage design; ensure creepage/clearance, isolation, and safety best practices
• Plan and execute prototype bring-up and high-power lab testing with safe procedures; debug failures and perform root-cause analysis
• Define verification plans and acceptance criteria and produce clear, review-ready test reports and evidence packages; support supplier/parts selection and DFM/DFT as designs transition to manufacturing

What you need

• 7+ years (or equivalent depth) in power electronics design and product development
• Strong experience with power converter/inverter topologies, architecture, device selection, gate-drive design, controller selection, feedback gain, stability margin, protection, and high-voltage, high-current PCB/layout practices
• Hands-on bring-up and debug experience with high-power hardware (safe lab practices, oscilloscopes, HV differential probes, current probes, power analyzers, network/stability analyzers)
• Ability to take designs from concept through prototype, verification, and production readiness with clear documentation to meet special and mission-oriented applications’ requirements

Nice to haves

• Demonstrated work on high-power systems (>10 kW)
• Aerospace experience: qualification mindset, configuration control, and familiarity with relevant test practices and EMI/EMC test workflows
• Motor drive experience: three-phase inverters for BLDC/PMSM, sensing, DC bus design, regen handling, and protection timing considerations
• High-voltage design experience (e.g., 200-800 VDC class) including isolation strategy and creepage/clearance design
• Power factor, total harmonic current distortion and EMI/EMC success in shipped products (e.g., MIL-STD-461/DO-160 standard specs) and ability to design for compliance early
• Safety qualification experience such as leakage current, ESD, lightning and surge test
• Circuit Simulation familiarity (LTspice/PLECS/Simetrix/Simplis/Simulink or similar) for validation and trade-off
• PCB CAD and layout tool experience and familiarity

What we have to offer

• Competitive compensation: $175,000 to $200,000 base salary + equity
• Exceptional healthcare benefits, Medical is 100% covered by the company
• Flexible PTO
• 401K
