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.

  • Define and establish development standards for reliability, scalability, and future team growth
  • Build scalable systems to support operational growth from millions of parts per year to millions per day
  • Implement logging, metrics, and automated testing to increase visibility and enable smarter decisions
  • Own and evolve a strategic roadmap that accelerates operations, reduces costs, and minimizes vendor reliance

Required Skills:

  • Bachelor’s degree in Software Engineering or a related field
  • 8+ years of experience building high-scale, reliable production systems
  • Full-stack experience with a track record of choosing and applying the right tools for the job
