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.

We value diversity as a critical factor in innovation and believe a diverse team is necessary to solve the toughest problems. We aim to create an inclusive environment that unleashes the full creativity of our team members from a wide variety of backgrounds and experiences. We provide equal employment opportunities to all individuals based on merit and without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, veteran status, or any other protected status under applicable laws.

Realta Fusion

Developing compact, scalable, modular - CoSMo fusion(TM) energy systems for the production of industrial heat and power.

Realta Fusion spun out of a groundbreaking physics experiment at the University of Wisconsin-Madison in 2022 and is developing the lowest capital and least complex path to commercially competitive fusion energy. We are applying advances in super-conducting materials, plasma physics, and computing power to a simple linear fusion reactor configuration. These advances allow for a much lower capex power plant, utilizing abundant fuel sources to provide a new, zero-carbon source of heat and power.
