Senior Power Electronics Engineer

About Helion

We are a fusion power company based in Everett, WA, with the mission to build the world's first fusion power plant, enabling a future with unlimited clean electricity. Our vision is a world with clean, reliable, and affordable energy for everyone.

Since Helion's founding in 2013, we have raised over $1 billion from long-time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors Soft Bank and Lightspeed to propel us forward. Our last prototype, Trenta, completed 10,000 high-power pulses and reached plasma temperatures of 100 million degrees Celsius (9 keV). We are now operating Polaris, our next prototype on the path to the world's first fusion power plant.

This is a pivotal time to join Helion. You will tackle real-world challenges with a team that prizes urgency, rigor, ownership, and a commitment to delivering hard truths - values essential to achieving what no one has before. Together, we will change the future of energy, because the world can't wait.

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
