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 $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.
What You Will Be Doing:
The Director of Plasma Physics will lead a multidisciplinary team of experimental and computational scientists, engineers, and technicians. The teams reporting into the Director of Plasma Physics are Experimental Physics, Diagnostics, MHD Simulations, Data Science, PIC/Kinetic Simulations, and Concept Prototyping. This team will drive simulations and experimental campaigns aimed at understanding plasma behavior and enhancing fusion performance in future systems. You will report directly to our Senior Director of Science in the organization housing Plasma Physics, Nuclear Science, Materials Science, Fuel Cycle, and Health Physics.
