Magnet Engineering Intern - Fall 2026

Thea Energy is building an economical and scalable fusion energy system utilizing arrays of mass manufacturable magnets and dynamic software controls. Commercial fusion energy can uniquely provide a abundant source of zero-emission power for a sustainable future. Thea Energy is leveraging recent breakthroughs in computation and controls to reinvent the stellarator, a scientifically mature form of magnetic fusion technology. Thea Energy was founded in 2022 as a spin-out of the Princeton Plasma Physics Laboratory and Princeton University, where the stellarator was originally invented. Thea Energy is currently designing its first integrated fusion system, Eos, based on its planar coil stellarator architecture which will produce fusion neutrons at scale and in steady-state.

Magnet Engineering Intern (onsite):

• Magnet Engineering Interns will support design and testing for Thea Energy’s HTS magnet prototyping programs.
• These programs include large scale HTS magnet systems and other fusion magnet-related related technology.
• Responsibilities may range from mechanical design, including CAD and FEA, to electromagnetic simulation, hardware prototyping, and execution of cryogenic testing.

Project Assignments Examples:

• High-temperature superconducting magnet engineering, manufacturing, and testing
• Cryogenic and vacuum systems
• Instrumentation and diagnostic systems
• Electrical and control systems engineering
• Mechanical engineering
• Various modeling, simulation, and data analysis roles including but not limited to COMSOL, ANSYS, Python, C++, MATLAB, Simulink, Microsoft Visio, - LabVIEW

It’s not necessary to meet all of the skillsets outlined above. Please feel free to send us a note and tell us why you would still be a great fit for this role or Thea Energy.
