Senior Power Electronics Engineer

Senior Power Electronics Engineer

The Senior Power Electronics Engineer will play a pivotal role in the design and development of the power electronics of our nuclear-driven high-speed generator. Responsibilities include but are not limited to the design of high voltage and high speed generator drives, DC-DC converter for high voltage batteries, and standalone and grid-tied inverters. You'll join the Power Conversion and Electrical Systems team responsible for converting mechanical energy generated from a nuclear reactor to electrical energy to deliver to customers. You will own power electronics design, analysis, simulation, and component selection. You will partner cross-functionally with top industry engineers at Radiant as well as vendors and partner organizations including government agencies. Your efforts will be instrumental to bringing the first nuclear microreactor to market. 

Responsibilities and Duties:  

• Design and develop power electronics for a nuclear power generator.
• Build detailed schematics, select components, PCBA layout, prototype, and validate hardware.
• Apply EMI/EMC strategies and underlying physics to engineering problems. 
• 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 building 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 inverter.

Required Skills and Qualifications:

• Bachelors degree in Electrical Engineering, specializing in power electronics.
• 8+ years of design experience designing high voltage and high power electronics.

Desired Skills and Qualifications:

• Expert with high voltage power semiconductor selection (Si/SiC/GaN, IGBT, Diodes, MOSFETs), gate driver, and protection circuit design.
• Strong understanding of different PWM switching techniques, DPWM, ZCS, ZVS.
• Expert with at least one of common power electronics tools such as PLECS, PSCAD, dSPICE, PSIM, or Simplorer.
• Solid understanding of capacitor and super-capacitors design and selection such as electrolytic, film, ceramic, tantalum.
• Proficiency in EMI/EMC filter design for stability, noise rejection, and surviving threat signals.
• Startup experience or ability to work in a fast-paced development environment.
• Demonstrated experience in embedded programming with C/C++.

Additional Requirements:

• Must be willing to work extended hours and weekends as necessary to achieve company goals.
