Power Electronics Engineer

Join the power movement as a Senior Power Electronics Engineer

Join the Pulsed Electrical Distribution System (PEDS) team at CFS as we begin development on the next-generation power supplies that will power ARC, the first grid- scale commercial fusion power plant. In 2027 our power supplies will supply SPARC with over 1GW of pulsed power. Develop a fusion engineering skillset and learn from SPARC as we demonstrate Q>1. Apply your power electronic experience to develop and qualify next-generation inverters and power supplies for ARC and beyond. We need a results driven power electronic engineer to lead our inverter development.

What you'll do:

• Lead the testing, qualification and commissioning of SPARC power supplies operating up to 2kV and 50kA
• Collaborate with power semiconductor device manufacturers to develop and qualify new Si and SiC devices for the next generation of high power (>10MVA) medium voltage power supplies for ARC tokamaks
• Design and develop high-power 4Q H-bridge inverter topologies using SiC MOSFETs, IGBTs, or other high-power semiconductor devices for use within ARC tokamak power supplies
• Lead the build, test, and validation of prototype 4Q power modules including the evaluation performance/losses and validate inverter protection mechanisms, fault detection, fault response time, and safe shutdown behavior
• Model and simulate power electronic circuits and components to evaluate and characterize converter performance, efficiency, stability, etc
• Coordinate with mechanical, PCB, firmware, and manufacturing engineering teams to develop control circuits and packaged sub modules
• Develop technical requirements, specifications and qualification plans for corresponding power circuit components (capacitors, magnetics, passives, etc.) and vendor selection
• Support cross-functional team technical developments such as power distribution, energy storage, RF and other systems delivering electrical power for fusion applications

What we’re looking for:

• 5+ years of related experience with Bachelor’s degree (or) a Master’s degree with 3+ years of experience with power electronics based systems
• Hands on product development experience for power electronic converter systems
• Extensive knowledge of semiconductor devices (IGBT, MOSFET, etc.)
• Experience with high power semiconductor devices (>1kA)
• Experience with modeling & simulation with analysis tools such as PLECS, PSPICE, MATLAB etc.
• Experience with packaging design of power conversion equipment and thermal management
• Hands on testing experience in a laboratory and use of oscilloscopes and other measurement equipment
• Excellent written and verbal communication skills, ability to conduct design reviews, organize and present results to both expert and non-technical audiences
• Results driven and ability to embrace and convince stakeholders on a change in design direction in pursuit of a high-quality product release

Bonus points for:

• Master’s degree in electrical engineering with a focus on Power Electronics
• Experience with DC power systems
• Familiarity with cascaded or interleaved systems utilizing smaller submodules to create a higher power output
• Energy storage experience

Must-have Requirements:

• Ability to lift up to 50lbs
• Perform activities such as standing, typing or sitting for extended periods of time
• Willingness to travel or work required nights/weekends/on-call occasionally
• Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
