Together, we will change the future of energy, because the world can't wait. What You Will Be Doing: We are hiring a Fuel Cycle Operations Engineer to commission, operate, test, and evaluate process equipment for Helion’s fusion fuel cycles. You will support Polaris operations and lead testing and evaluation of fuel cycle technologies and processes, including fuel balancing, isotope separation, water detritiation, and helium separation. Following alignment on the fuel cycle technology approach, you will also own commissioning of fuel cycle design units for Orion. You will report directly to the Fuel Cycle Operations Lead at our Everett, WA office. You Will: - Perform operations supporting Polaris including fueling, exhaust processing, and purification - Become a Tritium Authorized User to safely lead testing, commissioning and startup operations involving radioactive materials - Collaborate with our design teams to validate scalable fuel cycle processes through hands-on R&D activities, including system buildout, experimental testing and da
