About the company:
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 and 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). Now, we're turning up operations for Polaris, and working towards delivering the world's first fusion power plant.
More than ever, it's a pivotal time to join us and have the opportunity to solve real challenges to create a better energy future. You will see first-hand how we value urgency, rigor, ownership, and hard truths, knowing it will take each to do what no one has before. Joining us, you will push the boundaries of what's possible and transform humanity for the better - because the world can't wait.
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.

Together, we will change the future of energy, because the world can't wait.
About The Role
In this role, you will design and execution of the Balance of Plant (BoP) systems that make fusion power possible - from radiation shielding and gas handling to thermal management and heat recovery. This role is at the heart of translating fusion physics into practical power generation. You’ll build and lead teams that integrate Helion’s fusion generators with the systems that extract, move, and manage energy at scale. It’s a rare opportunity to lead multidisciplinary engineering at the edge of what’s possible and you'll have direct ownership of the systems that will define the world’s first fusion power plant. This is an onsite role that reports directly to the VP of Engineering at our Everett, WA office.
What You Will Be Doing:
- Build and lead high-performing engineering teams across mechanical, thermal, and fluid systems.
- Own the design and delivery of critical plant systems — radiation shielding, fuel and exhaust gas systems, vacuum infrastructure, and thermal management.
- Partner with nuclear, magnet, and systems engineering teams to integrate fusion generators into a cohesive power plant.
- Drive cross-functional engineering execution — from early concept to detailed design, manufacturing, and test.
- Set the technical bar for rigor, documentation, and accountability, ensuring safety, scalability, and reliability.
- Continually raise the standard for ownership, execution pace, and design clarity across your teams.
- Develop the next generation of Helion engineering leaders through mentorship and example.
