<div>About HelionWe 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 $1 billion 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 (9 keV). 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.</div>What You Will Be Doing:As a Senior Fluid Systems Technician, you will own major build efforts, mentor junior technicians, and collaborate directly with engineers to develop assembly processes, troubleshoot issues, and ensure high-quality system performance. As we scale production of our fusion prototype systems, we need experienced technicians who can lead the build, integration, and troubleshooting of complex fluid, vacuum, and cryogenic systems. This role demands technical mastery, leadership, and a commitment to building hardware at the pace required to make fusion a reality. Our Senior Technicians are leaders on the production floor. You will set the standard for precision, speed, and quality while mentoring the next generation of builders. Working side-by-side with engineers and operators, you'll play a pivotal role in scaling hardware that brings fusion power to the grid.
