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 SoftBank 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
This is a newly created role driven by rapid growth and increasing R&D demand. It’s a unique opportunity to join at a pivotal moment, helping shape how capacitor technologies scale from development into manufacturing while building the systems, teams, and processes that will define future success. You will lead the execution of capacitor R&D builds and pilot manufacturing, translating evolving engineering concepts into safe, repeatable processes. In this role, you will serve as a critical bridge between R&D and production, identifying manufacturability risks early, driving process improvements, and ensuring new technologies are ready to scale.

This role will provide leadership and operational oversight for a growing team of Engineering Technicians supporting first-shift manufacturing and R&D activities (Monday - Friday, 6:00 AM - 2:30 PM).
