Helion is building the world's first fusion power plant to deliver clean, reliable, and abundant electricity to the grid. Backed by Lightspeed, Peak XV and SoftBank VF.
About the role
We are looking for a Senior Materials Engineer to lead the development of materials health monitoring for Helion’s fusion generators. You will design, qualify, and deploy in-situ and ex-situ diagnostics to detect and quantify materials degradation under combined stimuli, including thermomechanical stress, radiation, high electric fields, and coolant environments.
What they're looking for
- BS with 10+ years, or MS/PhD with 5+ years, in Materials Science, Materials Engineering, Applied Physics, Nuclear Engineering, or related field
- 5+ years (with PhD or MS) or 10+ years (with BS) of experience in at least one of:
- Materials diagnostics / NDE / SHM (strain, acoustic, optical, EM, fiberoptic, etc.)
- Familiarity with data analysis / feature extraction for degradation detection (Python preferred)
- Experience designing and executing coupled-stimuli experiments (e.g., thermomechanical, electrothermal, irradiation with stress)
- Experience embedding or integrating sensors into structural materials (ceramics, composites, polymers, or metals)
More about this role
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 $1.5 billion from long-time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as new investors including Thrive Capital, LightSpeed Venture Capital, SoftBank, and others to propel us forward. Our current prototype, Polaris, has reached record-breaking plasma temperatures of 150 million degrees Celsius (13 keV). Helion is continuing to iterate and on the path to the world's first fusion power plant, Orion.
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.
