Electrical Engineer (High Voltage Systems) – Contractor / Part-Time
About The Position
Eos Atomics is developing next-generation Neutral Beam Injection (NBI) systems for the emerging commercial magnetic fusion industry. 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. We are seeking a High-Voltage Electrical Engineer to support the design, analysis, and early commercialization of medium- and high-energy Neutral Beam Injection subsystems. This role is ideal for an electrical engineer with deep experience in HV power systems, pulsed or CW HV architectures, insulation and grounding strategies, and safety-critical electrical design, who wants to contribute meaningfully without committing to a full-time role. You will work closely with plasma physicists, mechanical engineers, and systems engineers to translate fusion-grade requirements into robust, manufacturable electrical designs.
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.
- Demonstrated experience designing or supporting systems operating at ≥10 kV (experience above 50–100 kV strongly preferred).
- Strong understanding of: High-voltage insulation, grounding, and shielding
- HV safety and fault mitigation
- Power electronics fundamentals
- Comfortable working in low-bureaucracy, early-stage R&D environments.
Nice To Haves
- 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.
- Exposure to test stand commissioning and experimental hardware.
Responsibilities
- 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).
- Define electrical interfaces between HVPS, ion sources, extraction grids, beamline components, and diagnostics.
- 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.
- Advise on high-voltage safety practices, interlocks, grounding schemes, fault detection, and safe commissioning procedures.
- Contribute to early hazard analyses, FMEA, and risk-retirement plans for HV subsystems.
- Support alignment with relevant standards (e.g., IEC, IEEE, DOE lab best practices) where applicable.
- Review HVPS vendor specifications, drawings, and test data.
- Support supplier technical due diligence and integration planning.
- Provide engineering input for prototype builds, test stands, and early customer demonstrations.
- Produce concise design documentation, schematics, and interface definitions suitable for internal use, partners, and future regulatory review.
- Mentor junior engineers or cross-disciplinary team members on HV fundamentals as needed.
