About the role
- Our focus is on compact, continuous-wave, medium- and high-energy neutral beams that dramatically reduce cost, footprint, and operational complexity compared to legacy systems used in national laboratories.
- We are assembling a small, elite engineering team to bridge accelerator physics, high-voltage power electronics, and fusion-grade reliability as we move from prototype systems toward commercial deployment.
- Define electrical interfaces between HVPS, ion sources, extraction grids, beamline components, and diagnostics.
Responsibilities
- High-Voltage System Design & Analysis
- Contribute to the design of high-voltage power supply (HVPS) architectures supporting medium- and high-energy NBI operation (tens to hundreds of kV, CW and/or pulsed).
- Perform voltage stress, insulation coordination, creepage/clearance, and grounding analysis for vacuum and atmospheric systems.
- Support trade studies comparing floating vs grounded HV architectures, isolation strategies, and modular scaling approaches.
- Support alignment with relevant standards (e.g., IEC, IEEE, DOE lab best practices) where applicable.
- Support supplier technical due diligence and integration planning.
- Provide engineering input for prototype builds, test stands, and early customer demonstrations.
Requirements
- Bachelor's or Master's degree in Electrical Engineering or equivalent practical experience.
- 5+ years of hands-on experience with high-voltage electrical systems, power electronics, or accelerator-adjacent infrastructure.
- Strong understanding of:
Nice to have
- High-voltage insulation, grounding, and shielding
- HV safety and fault mitigation
- Power electronics fundamentals
- Comfortable working in low-bureaucracy, early-stage R&D environments.
- Experience with particle accelerators, ion sources, neutral beam systems, RF systems, or fusion devices.
- Familiarity with vacuum systems and HV operation in vacuum.
- Experience with continuous-wave (CW) high-power systems (as opposed to purely pulsed systems).
- Prior work at a national laboratory, accelerator facility, fusion program, or advanced energy startup.
Compensation
- $50k-$100k
Benefits
- Contribute to early hazard analyses, FMEA, and risk-retirement plans for HV subsystems.
Company info
- 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.
