NBI Scientist (Experimental Negative-Ion Injector)

About the role

Bring your negative-ion source and accelerator expertise to Realta Fusion and help build the NBI technology powering the next generation of fusion energy. The NBI Scientist (Experimental Negative-Ion Injector) will provide dedicated negative-ion source and accelerator hardware capability as the program moves beyond concept development, simulation, and partner-supported early testing. This role will support the design, development, testing, and optimization of negative-ion injector hardware and associated systems. The position will work closely with scientific and engineering teams to translate beam-physics requirements into experimental hardware and support the advancement of Realta’s NBI technology. What we are working on is hard… and hugely important. Realta Fusion is assembling a talented team bound together by a passion to solve humanity's biggest challenge with first-of-a-kind technology.

Responsibilities

• Primary experimental responsibility for NBI-based negative-ion source development and test-bed operation.
• Bridge source and ion-optics modeling with operating injector hardware.
• Build dedicated negative-ion commissioning knowledge for future HAMMIR systems.
• Complement with positive-ion NBI operational experience with in-depth expertise in negative-ion-specific hardware.

Requirements

• Hands-on experience with negative-ion or ion sources, extracted beams, high-voltage accelerator systems or comparable injector hardware.
• Vacuum systems, plasma/source operation, beam diagnostics, conditioning and experimental troubleshooting.
• Understanding of extraction, co-extracted electrons, accelerator grids and source-to-beam coupling.
• Ability to design test plans, commission hardware and translate observations into design changes.

Benefits

• Competitive compensation package, including equity stock options
• Comprehensive benefits including health, dental, and vision insurance, plus a retirement savings plan
• Flexible paid time off (PTO) to support work-life balance
• Work and live in Madison, Wisconsin — one of America's most livable and vibrant cities
