Thea Energy is a fusion startup developing software-controlled, tunable rectangular magnets (planar coils) for stellarator-style magnetic confinement reactors.
About Thea Energy: 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. Position Overview: Thea Energy is looking for an experienced, highly motivated Director - Mechanical Engineering to join its rapidly growing team. You will have ownership of the mechanical design and development of primary and secondary components and subsystems in the development of Thea Energy’s integrated stellarator fusion systems. You will be responsible for structural and thermomechanical design, manufacturability, development, and commissioning of these components. You will drive requirements definition, design trades, and integration across disciplines. You will build and lead an integrated team drawing from disciplines including mechanical design, structural and stress analysis, thermal/fluids analysis, materials engineering, manufacturing and fabrication engineering, nuclear engineering, and vacuum systems engineering. The Thea Energy team is comprised of driven, creative, and fun individuals passionate about solving complex problems.
