About the role
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 hardware designs for systems related to vacuum systems on Helion's fusion generators. You will solve multidisciplinary engineering problems that are necessary for deploying fusion energy to the world and act as a culture driver on a growing team. You will report to the Senior Manager of Mechanical Engineering, and this is an onsite role located at our Everett, WA office. You Will: Own design of novel high-vacuum system for pulsed fusion generator and prototype Drive system definition from
requirements derivation, high-level CONOPs, P&ID and component selection through hardware commissioning Perform analysis with in-house and out-of-house tools and hold design reviews to gather feedback and iterate to a fully functioning system Work hands-on alongside experienced technicians to implement your hardware designs Work cross-functionally to negotiate interfaces with other fusion generator subsystems Learn from experts to expand your engineering skillset and domain knowledge Troubleshoot hardware issues as they arise on integrated fusion generators Required Skills: Bachelor's degree in engineering 5+ years of professional experience delivering on full-scope engineering projects (including schedule ownership) Experience applying engineering first-principles and method-based thinking to challenging problems Hands-on exposure to a variety of engineering disciplines (fluids, mechanical, controls) Experience using CAD software (e.g. NX, Solidworks)
