Job description

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: You will own the full lifecycle of superconducting hardware-from simulation and design through build, test, and integration-while coordinating across internal teams and external partners to qualify technologies for deployment in Helion's fusion machines. You will report to the Senior Director of Science and this is an onsite role located at our Everett, WA office. You Will: - Analyze magnetic fields and their coupled effects (e.g., Lorentz forces, thermal loads, structural stress) using tools such as COMSOL and ANSYS - Evaluate mechanical loading and failure modes in high-field superconducting environments - Design, build, test, and iterate superconducting magnet systems in both standalone test stands and integrated fusion machines - Develop experimental plans and diagnostics to validate performance under realistic operating conditions - Analyze the impact of superconducting field configurations and architectures on plasma performance - Collaborate closely with plasma physicists and machine designers to optimize system-level outcomes Required Skills: - Demonstrated experience delivering a functional superconducting system that has been successfully deployed or operated in a real-world application - Strong background in electromagnetics, superconductivity, and multiphysics modeling - Hands-on experience designing and testing superconducting magnets or related systems - Proficiency with COMSOL, ANSYS, or equivalent simulation tools - Experience working across disciplines including mechanical, electrical, and plasma physics domains - Proven ability to independently drive complex technical projects from concept to execution Benefits Our total compensation package includes benefits, including but not limited to: - 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 Helion is an equal opportunity employer and value diversity at our company.
