Join the power movement as a Lead RF Electro-Mechanical Technician

We are seeking a highly motivated RF Electro-Mechanical Technician to join our team of physicists, engineers, and technicians in our core mission: accelerating the development of fusion energy.

In this highly independent working lead role, you will navigate a dynamic environment split between cutting-edge R&D and assembly-focused manufacturing. You will act as the vital interface between the shop floor and engineering, translating engineering priorities into daily action for a small technician team.
We know the perfect candidate might not be an expert in every single task listed below on day one. What matters most is that you are a reliable leader, a strong communicator, and a skilled technician ready to turn wrenches, learn fast, and bridge the gap between engineering and assembly.

What you'll do:

  • Hands-on Assembly & Fabrication:
    • Use hand and power tools to assemble complex components for RF transmitters
    • Build I&C (Instrumentation and Controls) cabinets
    • Integrate various sensors and mechanical systems
  • High-Voltage & Testing:
    • Work safely and confidently with 480V electrical systems
    • Handle RF and electrical test equipment to validate builds and ensure systems are functioning correctly from start to finish
  • Precision Work:
    • Perform detailed technical tasks, including plumbing, wiring, and soldering, while maintaining meticulous attention to detail and cleanliness
    • Work with other technicians and equipment operators in the I&C equipment commissioning and troubleshooting
  • Safety & Quality Standards:
    • Operate and maintain highly technical apparatus with a steadfast commitment to safety and quality, following the current team's standards
    • Ensure safety is always the first priority in any testing activity
    • Report on and be accountable for progress to their supervisor


What we're looking for:

  • High school diploma, equivalency certificate, or higher (Note: Graduation from a two-year technical school or military technical training is highly acceptable and welcomed)
  • Minimum of 5 years' experience with hand/power tools, machine shop equipment, and a variety of technical support skills (mechanical/electrical assembly, plumbing, soldering, and wiring)
      • Hands-on experience working safely with high voltage (up to 480V)
      • Hands-on experience with RF and electrical measurement/test equipment
  • Strong foundational understanding of mechanical and electrical systems, alongside basic computer proficiency (email, video conferencing, data entry, etc.)
  • Excellent communication and teamwork skills. Ability to take direction from leadership, work independently, and thrive in an agile environment balancing R&D and manufacturing demands


Bonus points:

  • Soldering of RF components on circuit boards.
  • Ability to read and interpret complex electrical schematics and wiring diagrams


Must-have requirements:

  • Ability to occasionally lift up to 50 lbs
  • Perform activities such as stooping, climbing, typing, standing, sitting, etc. for extended periods of time
  • Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
  • Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
  • Willingness to occasionally travel or work required nights/weekends/on-call
