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:

We are seeking highly motivated Computational Plasma Physicists to join our team, focusing on stellarator and fusion plasma physics simulations. The ideal candidate will possess a strong background in computational physics, with a particular emphasis on MHD stability in stellarators and stellarator optimization. You will work with minimal supervision, contributing to cutting-edge research and development in Thea Energy’s stellarator systems.

  • Develop and implement algorithms for analyzing and improving stellarator configurations.
  • Conduct simulations and analysis of fusion plasma behavior in stellarators, using advanced computational models.
  • Collaborate with cross-disciplinary teams to refine designs and improve the performance of stellarator systems.
  • Perform data analysis, model validation, and provide insights into the physical mechanisms governing plasma behavior.
  • Prepare technical reports, presentations, and publications based on simulation results and optimization findings.
