Senior Power Electronics Engineer
What You Will Be Doing:
You will support the design, development, and optimization of the core energy management systems for Helion’s fusion generators. This includes high-voltage pulsed power delivery, energy recovery, redistribution networks, and AC grid-tie systems. In this role, you’ll drive design excellence, mentor other engineers, and contribute directly to one of the most ambitious energy challenges of our time. This is an onsite role reporting to the Senior Manager of Electrical Engineering at our Everett, WA office.
You Will:
Design, test, and troubleshoot high-voltage power systems that drive pulsed magnetic coils
Oversee procurement, construction, and commissioning of electrical systems delivering <1 ms pulses at up to 5 MA and 40 kV
Develop system architecture and collaborate on schematics and installation drawings
Lead design reviews, validating cost-effective, scalable, and reliable solutions
Support generator commissioning and operations with an eye toward improving future builds
Own engineering rigor—cost, schedule, and resource estimates—for your scope of work
Mentor teammates and contribute to technical growth across electrical and cross-functional engineering teams
Required Skills:
8+ years experience in power electronics, solving complex electrical engineering problems from design to delivery
Bachelor’s or Master’s degree in Electrical Engineering, Physics, or related field
Proven experience designing, fabricating, installing, and testing electronic systems
Strong working knowledge of power switching components (IGBTs, MOSFETs, SCRs)
Deep understanding of engineering principles and experience driving project delivery from design through execution
Advanced troubleshooting skills using tools like oscilloscopes, pulse generators, spectrum analyzers, and electronic loads
Proficiency in LTSpice, SIMetrix/SIMPLIS, Altium, MATLAB, and Microsoft Office
#LI-Onsite #LI-KL1
