We're turning the promise of science into reality.

We’re looking for candidates who are passionate about realizing our mission: A future where all people have affordable access to reliable, abundant, and environmentally friendly fusion‑generated electricity.

The successful candidate will participate in the research and development of long‑pulse plasma sources, extraction and acceleration systems, and beamline components through the design and construction of subsystem prototypes on various test stands and by working closely with experimentalists and computational science staff.

• Design, analyze, and optimize neutral beam injection systems, including ion sources, accelerators, neutralizers, beamlines, and beam dumps
• Specify and integrate vacuum, cryogenic, cooling, and gas handling subsystems
• Collaborate with plasma physicists to meet experimental performance requirements
• Interface with controls, diagnostics, and data acquisition teams
• Oversee vendor interactions, component testing, and acceptance reviews
• Develop diagnostics for the high‑power NB (Secondary electron emission detectors, calorimeters, optical diagnostics, etc.)

• Direct experience with neutral beam injection systems and/or ion sources
• Experience with magnetically confined plasma
• Proficiency with simulation codes (COMSOL, ANSYS, Solid Works)
• Thermal, structural, and/or electromagnetic analysis
• Experience in designing and operating plasma and/or beam diagnostics
• High vacuum systems
• Experience with high‑voltage systems, pulsed power, particle accelerators and/or fusion devices
