Senior Power Electronics Engineer

The role

The Senior Power Electronics Engineer will design and develop power electronics for a nuclear-driven high-speed generator. This includes designing high-voltage generator drives, DC-DC converters, and inverters.

What you will do

• Design power electronic systems to convert AC and DC power sources into stable grid compatible voltages and frequencies
• Take ownership and configure active rectifiers, inverters, and dc/dc converters
• Apply EMI/EMC strategies to system design, selection of line filters, capacitors, grounding and isolation
• Utilize expertise in design and validation of gate drivers, power stages, magnetics, and controls
• Conduct modeling and detailed simulation of inverters
• Own the design and build a fully functioning inverter autonomously
• Perform circuit formal analysis, e.g., de-rating and worst-case circuit analysis
• Optimize loss, efficiency, and conduct thermal analysis of the inverter

Required qualifications

• Bachelor's degree in Electrical Engineering, specializing in power electronics
• 6+ years of design experience designing high voltage and high-power electronics
• Expert with high voltage power semiconductor selection (Si/SiC/GaN, IGBT, Diodes, MOSFETs), gate driver, and protection circuit design
• Strong experience in high voltage (HV) power electronics design (+800V) including AC/DC inverters, and DC/DC converters
• Strong understanding of different PWM switching techniques, DPWM, ZCS, ZVS
• Proficiency with at least one of the common power electronics tools such as PLECS, PSCAD, dSPICE, PSIM, or Simplorer
• Expertise in EMI/EMC filter design for stability, noise rejection, and surviving threat signals
• Solid understanding of capacitor and super-capacitor design and selection, such as electrolytic, film, ceramic, and tantalum

Nice to have

• 8+ years of design experience designing high voltage and high-power electronics
• Experience in magnetics design including transformers and inductors for high-frequency power conversion applications
• Familiarity with functional safety standards (IEC 61508 or equivalent) and fault-tolerant design practices
• background in aerospace, defense, or nuclear applications
• Startup experience or ability to work in a fast-paced development environment
• Demonstrated experience in embedded programming with C/C++
