About The Position

Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils, thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future. We are looking for talented technical interns to join our stellar team for the summer or during the school year! Program Details: Summer 12-16 week internship program for 40 hours per week or Flexible school year internship for 30+ hours per week. For school year internships, expected time dedication is flexible and tailored to your academic schedule. 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 technology. Responsibilities may range from mechanical design, including CAD and FEA, to electromagnetic simulation, hardware prototyping, and execution of cryogenic testing.
