Capacitor R&D Supervisor

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.

The Supervisor of Capacitor Manufacturing R&D leads the day-to-day execution of capacitor development and R&D manufacturing activities. This role directly oversees Engineering Technicians supporting prototype builds, process development, and early manufacturing readiness, while partnering closely with engineering, production, and EHS.

The supervisor is accountable for safe execution, technical rigor, team performance, and delivery of R&D build objectives. This role focuses on translating engineering intent into executable work, building technical capability within the team, and ensuring R&D efforts scale cleanly toward manufacturing.
