About the job
Join Our Mission at Helion
Helion is at the forefront of innovation, striving to create the world’s first fusion power plant based in Everett, WA. Our goal is to provide limitless clean energy to the world, ensuring a sustainable and affordable energy future for all.
Since our establishment in 2013, we have attracted over $1 billion in funding from renowned investors like Sam Altman, Mithril, and Capricorn Investment Group, alongside new partnerships with SoftBank and Lightspeed. Our latest prototype, Trenta, has achieved remarkable milestones, including 10,000 high-power pulses and plasma temperatures of 100 million degrees Celsius (9 keV). Currently, we are advancing with Polaris, our next-generation prototype, as we move closer to realizing our vision.
This is an exciting time to become part of Helion’s team. You will face significant challenges alongside a group that values urgency, precision, accountability, and the courage to confront difficult truths—qualities that are essential to achieving unprecedented breakthroughs in energy. Together, we can redefine the future of energy, because the world cannot afford to wait.
Your Role:
As a Senior Power Electronics Engineer, you will play a crucial role in designing, developing, and optimizing the core energy management systems for Helion’s fusion generators. Your responsibilities will encompass high-voltage pulsed power delivery, energy recovery, redistribution networks, and AC grid integration. You will drive design excellence, mentor fellow engineers, and directly contribute to solving one of the most significant energy challenges of our time. This position is on-site, reporting to the Senior Manager of Electrical Engineering in our Everett, WA office.
Key Responsibilities:
Design, test, and troubleshoot high-voltage power systems for 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, ensuring cost-effective, scalable, and reliable solutions are implemented.
Support generator commissioning and operations to enhance future builds.
Own engineering rigor—including cost, schedule, and resource estimates—for your scope of work.
Mentor teammates and foster technical growth within electrical and cross-functional teams.
