Electrical Engineer (High Voltage Systems)
About The Position
Eos Atomics is a deep-tech fusion startup focused on developing next-generation Neutral Beam Injection (NBI) systems for the commercial magnetic fusion industry. The company aims to create compact, continuous-wave, medium- and high-energy neutral beams that are more cost-effective and less complex than traditional systems. They are building a specialized engineering team to integrate accelerator physics, high-voltage power electronics, and fusion-grade reliability for commercial deployment. This role specifically supports the design, analysis, and early commercialization of NBI subsystems, targeting engineers with significant experience in high-voltage power systems, pulsed or CW HV architectures, insulation, grounding, and safety-critical electrical design. The engineer will collaborate with plasma physicists, mechanical engineers, and systems engineers to develop robust and manufacturable electrical designs for fusion-grade requirements.
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
- Strong understanding of: HV safety and fault mitigation
- Strong understanding of: 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.
Benefits
- Flexible workload (e.g., 5–20 hrs/week depending on phase).
- Contractor or part-time structure to match availability.
- Opportunity to scale involvement over time as programs mature.
- Potential pathway to expanded role as Eos Atomics transitions from R&D to commercial delivery.
