Senior Electronics Technician

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 $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 (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 You will work directly with the Electrical Engineering team to build, modify, debug, and sustain the low and high voltage electronics that enable Helion’s fusion machines to operate. You will support pulsed‑energy drive systems, diagnostics, controls, and energy recovery hardware by hands‑on assembly, wiring, instrumentation setup, and real‑time troubleshooting in lab and production environments. You will be expected to independently execute complex bench-level work, identify hardware issues through measurement and observation, and partner with engineers to resolve problems quickly and safely in high‑noise, high‑field environments. You will report to our Production Manager at our Everett, WA facility.
