About the company:

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.

Position Overview:
Thea Energy is seeking for an experienced, organized, and motivated systems engineer. This position will work on an interdisciplinary team to integrate numerous first-of-a-kind technologies while developing scalable processes and procedures.
