Helion is building the world's first fusion power plant to deliver clean, reliable, and abundant electricity to the grid. Backed by Lightspeed, Peak XV and SoftBank VF.
About the role
Helion is hiring an Experimental Scientist to support the development, deployment, calibration, and operation of plasma diagnostics for Helion’s fusion generators. In this role, you will contribute to hands-on experimental work across plasma diagnostics, test campaigns, and high-vacuum systems while partnering closely with scientists, engineers, machine operators, and data teams. This is an onsite role that reports directly to our Director of Plasma and Nuclear Science at our Everett, WA office.
What they're looking for
- Ph.D. in physics, electrical engineering, aerospace engineering, or a related discipline, with a focus on plasma science, diagnostics, or high-vacuum instrumentation
- Relevant hands-on experience with plasma systems, advanced laboratory environments, high-vacuum systems, pulsed-power systems, or complex experimental hardware
- Experience supporting the design, build, calibration, troubleshooting, or operation of plasma diagnostics such as interferometry, spectroscopy, Langmuir probes, magnetic coils, electrostatic diagnostics, optical diagnostics, or related measurement systems
- Ability to operate autonomously on day-to-day technical tasks, apply critical thinking across multiple inputs, and escalate issues appropriately when technical risk, scope, or priority requires broader alignment
More about this role
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.
