Lead Fusion Systems Technologist

Realta Fusion is a rapidly growing start-up developing compact magnetic mirror fusion energy systems to address the biggest challenge of our time — tackling global climate change while ensuring a sufficient energy supply for at least ten billion people on (and off) earth. We are building a team with diverse talents dedicated to making fusion energy a real solution to humanity’s most pressing problem. This hands-on Lead Fusion Systems Technologist would lead the assembly, integration, and commissioning of Realta's fusion hardware. The ideal candidate is a 10–15+ year national-laboratory or large-facility technician who has brought particle accelerators, fusion devices, or similarly complex scientific systems to operational status. Responsibilities

• Lead UHV assembly, cleaning, leak checking (He mass-spec), bakeout, and pump-down for fusion vessels and beamlines
• Commission high-voltage power supplies, RF heating systems (ICRH/ECRH), magnet supplies, and neutral beam injectors
• Plan and execute critical lifts of high-value fusion hardware; serve as Lift Director for complex rigging operations
• Coordinate and sequence work of junior technicians, crafts personnel, and vendor reps on the experiment floor
• Author traveler documents, assembly procedures, commissioning checklists, and as-built records
• Champion safe work practices for HV, UHV, RF, magnetic-field, and heavy-lift operations

Required Qualifications

• 10–15+ years hands-on experience at a national lab, accelerator facility, or fusion research center (or equivalent)
• Demonstrated UHV expertise: clean assembly, He leak detection, RGA interpretation, bakeout to <1×10⁻⁷ Torr
• Experience commissioning major scientific systems — accelerators, fusion devices, beamlines, or equivalent
• Hands-on HV experience (>10 kV); proficiency with LOTO/LOTOTO and HV personnel protection systems
• Critical lift experience; familiarity with ASME B30 or DOE rigging/lift safety standards
• Experience with RF systems, cryogenics, superconducting or resistive magnets, or precision alignment (any combination)
• Ability to read engineering drawings, P&IDs, schematics, and wiring diagrams

Preferred Qualifications:

• Experience at DOE labs (PPPL, Fermilab, SNS, SLAC, etc.), CERN, TAE, CFS, or equivalent
• Journeyman craft credentials (electrician, pipefitter, millwright, or similar)
• Experience with neutral beam injectors, ICRH, ECRH, or tandem/magnetic mirror systems
• DOE radiological worker training; NQA-1 or CGD quality program experience
• Vacuum-compatible TIG welding (stainless or aluminum)
