Senior Power Electronics Engineer

The role

You will lead the design and integration of high-power power conversion hardware for aerospace motion and electrical systems. This includes architecting converters, driving prototype bring-up, and partnering with multiple engineering teams to deliver mission-ready hardware.

What you will do

• Architect and design high-power converters/inverters for aerospace products
• Select and apply Si, SiC, and/or GaN power devices
• Design gate-drive, controller, feedback stability, magnetic components, sensing, and protection
• Design topologies and the power stage
• Drive thermal design with mechanical engineering and validate performance
• Own EMI/EMC strategy for aerospace environments
• Lead schematic capture and review PCB layout
• Plan and execute prototype bring-up and high-power lab testing
• Define verification plans and acceptance criteria
• Support supplier/parts selection and DFM/DFT

Required qualifications

• 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
• 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

Nice to have

• 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

Benefits

• Medical is 100% covered by the company
• Flexible PTO
• 401K

Before you apply

• Applicants must be U.S. Citizens or U.S. Permanent Residents (Green Card holders)
• Candidates must be able to comply with applicable export control laws and access requirements
