## 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
