Senior Computational Plasma Scientist - MHD

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 $1billion from long‑time investors such as Sam Altman, Mithril, and Capricorn Investment Group as well as 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 (9keV). We are now operating Polaris, our next prototype on the path to the world’s first fusion power plant. 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 Helion is hiring a Computational Plasma Engineer. You will communicate with engineers and scientists on a wide range of topics including plasma physics; magnetic field diffusion and eddy currents; circuit response and coupling; and structural mechanics. You will report to our Manager of Computational Science at our Everett, WA office. You Will: Run our internal MHD code to simulate FRC dynamics for a wide range of simulation conditions from the initial simulation setup to the post‑processing of the results. Calculate FRC dynamics, circuit response, and magnetic loads to help develop our fusion generators. Perform analysis to interpret experimental measurements by reproducing the experimental conditions with our internal MHD code. Collaborate with and learn from experts to expand your technical skillset and domain knowledge. Communicate simulation results and findings with accuracy and rigor to both scientists and engineers by preparing reports, presentations, and graphics. Required Skills PhD. with 5+ years of industry experience in physics, engineering, or a related field of study with an emphasis in electromagnetics. Knowledge of magnetic field diffusion and eddy currents. Ability to understand FRC physics. Experience writing scripts to analyze output, parse files, and create plots in a common coding language (e.g., MATLAB, Fortran, C, Python, etc.). Experience with MATLAB and Fortran. Experience using computer simulation tools for circuit dynamics, fluid dynamics, transient magnetics, or plasma dynamics. Benefits Medical, dental, and vision plans for employees and their families. 31 days of PTO (21 vacation days and 10 sick days). 10 paid holidays, plus company‑wide winter break. Up to 5% employer 401(k) match. Short‑term disability, long‑term disability, and life insurance. Paid parental leave and support (up to 16 weeks). Annual wellness stipend.
