About the role

At Eos Atomics, we're driven to accelerate the energy transition to clean and affordable fusion energy, for a sustainable and energy-abundant future.
We are seeking an experienced physicist with specialized expertise in Neutral Beam Injection (NBI) systems for plasma heating in fusion devices.
Spearhead innovative solutions to overcome challenges in beam energy, neutralization efficiency, and beam-plasma coupling

Design, develop, and optimize neutral beam injection systems for plasma heating and current drive applications
Lead experimental campaigns to characterize NBI performance and integration with plasma operations
Collaborate with multidisciplinary teams including vacuum systems, power supplies, diagnostics, and plasma physics groups
Develop physics models and simulation tools for NBI system performance prediction and optimization
Autonomy to build your technical team and establish engineering culture

Minimum 7+ years of hands-on experience with neutral beam injection systems for fusion applications
Demonstrated expertise in one or more core NBI subsystems: ion sources, accelerator grids, neutralizers, beam dumps, or power delivery systems
Strong understanding of beam-plasma interactions and the role of NBI in plasma heating, current drive, and momentum injection
Experience with relevant diagnostic techniques for beam characterization and performance assessment
Proven track record of publications in peer-reviewed journals on NBI or related fusion technologies
Experience with project management and coordination of technical teams

Experience with negative-ion-based NBI systems for high energy applications (>100 keV)
Background in Multicusp-Filament, RF-driven or other advanced ion source technologies
Familiarity with tokamak or stellarator plasma physics and operational constraints
Knowledge of beam-line component cooling and high-heat-flux engineering
Experience with ITER, JET, DIII-D, EAST, KSTAR, JT-60SA, or other major fusion facilities
Understanding of broader fusion integration challenges and reactor-relevant conditions
Self-starter who thrives in resource-constrained environments
Demonstrated history of taking ownership of challenging technical problems

Eos Atomics is not a traditional defense contractor. We're a deep-tech fusion startup with ambitious goals and the drive to deliver impossibly cool technology in service of a greater good. We believe that fusion will transform humanity's relationship with energy and holds the key to unlocking a sustainable future across the board.
We're builders, fusion wonks, dot connectors, and creative problem solvers.
We're self-starters-we take ownership and hit the ground running.
We move at a pace that allows us to reach milestones in months, not years. Monday's idea is Friday's prototype.
Everyone at Eos Atomics is responsible for meaningful, mission-driven work.
This is hard tech, solving hard problems.
Evolve to Innovate - Amplify what's good; change what isn't.
Pressure-test, iterate, and seek diverse views, experiences, and expertise.
