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 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, 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.

What You Will Be Doing :

We are hiring a Senior Design Engineer to own the design of capacitors used for energy storage in Helions fusion generators. This position provides a unique opportunity to collaborate across technical teams to optimize complex electromechanical design. You will accelerate Helions transition from rapid prototyping to generator mass manufacturing, delivering on Helions mission of providing clean electricity for the planet.

You will :

• Own capacitor design from requirement derivation, prototyping and testing, through to mass-manufacturing
• Work across technical teams to deeply understand how capacitors are used within our pulsed power circuits to optimize capacitor design requirements for Helions top-level generator goals
• Design, prototype, and test new capacitor designs to increase energy density, drive down cost, reduce electrical losses, improve manufacturability, and enable rapid manufacturing scaling
• Perform detailed capacitor design and qualification testing in support of near-term fusion generator builds, and owning resolution of capacitor anomalies during generator test operations
• Partner with our world class supply chain, manufacturing engineering, and production teams to scale Helions capacitor manufacturing from 10 MJ to 100,000 MJ per year in the next decade
• Enable high volume capacitor production via creative capacitor design and incorporation of mass manufacturing process
• Develop Helions long-term capacitor design strategy, including mitigating future vendor and supply chain risks, and incorporating emerging technologies to maintain Helions technological lead
