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 an experienced and motivated Engineering Program Manager to lead a large, complex custom product development program within the fusion energy industry. This is a highly visible role in the organization leading development of core magnet technology. This role will act as a force multiplier by increasing development velocity and raising the bar on execution standards. You will oversee the design, build, and test phases of critical hardware, ensuring the successful delivery of components that will advance fusion technology.
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.
Diversity and Inclusion:
Thea Energy is an equal opportunity employer committed to creating a company of diverse backgrounds.
