We’re not just looking for physicists – we’re looking for bright, hands-on problem-solvers ready to help design, build, and test the hardware that will shape the future of fusion energy!

Engineering Interns at Realta Fusion will provide hands-on, part-time support to one of several exciting areas of engineering and design work:

  • Mechanical Design & Fabrication
  • Hardware Assembly, Integration & Test
  • Electrical Engineering & Diagnostics

Mechanical Design & Fabrication Co-ops

  • Support mechanical design of fusion hardware components using CAD (SolidWorks or similar), from concept sketches through detailed drawings
  • Assist with drafting specifications and coordinating with machine shops and vendors on prototype fabrication
  • Contribute to design reviews and iterate on designs based on fabrication, prototyping, and test feedback

Hardware Assembly, Integration & Test Co-ops

  • Assist with the assembly, integration, and testing of vacuum systems, magnet systems, and mechanical structures supporting Realta’s fusion devices
  • Support hands-on build activities in the lab and machine shop, including fixturing, alignment, and instrumentation setup
  • Gain experience working safely with high vacuum systems, precision hardware, and lab equipment

Electrical Engineering & Diagnostics Co-ops

  • Support the design, fabrication, and testing of diagnostic and instrumentation hardware for Realta’s fusion devices, including sensors, signal conditioning, and data acquisition electronics
  • Assist with electrical design and integration of power systems, control circuitry, and cabling supporting magnets, vacuum systems, and pulsed power hardware
  • Support bring-up, calibration, and troubleshooting of diagnostic and electrical systems in the lab, working closely with mechanical and controls engineers

Applications are reviewed on a rolling basis. Apply early!

Minimum Qualifications

  • Currently pursuing a bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Nuclear Engineering, Electrical Engineering, or a related field.
  • Ability to work on-site at either the Realta Fusion office (Madison, WI) or the Physical Sciences Laboratory (near Stoughton, WI) – whether commuting locally for a part-time co-op or relocating for a full-time co-op.
  • Authorized to work in the United States.
  • A passion for hands-on design, fabrication, and building things; prior project, competition (e.g., Formula SAE, rocketry, robotics), or shop experience is a plus.
  • Demonstrated strong work habits and a commitment to safety.

Part-Time Internship Timeframe 

  • Up to 20 hours/week, with flexible scheduling to accommodate class schedules during the academic year.
