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 a highly motivated plasma physicist to join our team, focusing on the analysis, simulation, and optimization of the divertor region of a stellarator magnetic field. The ideal candidate will possess a strong background in plasma physics, with a particular emphasis on plasma fluid models, neutral particle models, and/or atomic processes within plasmas. Experience with the boundary of fusion devices is a plus. You will work on a dynamic team, contributing to cutting-edge research and development in Thea Energy’s stellarator systems.

  • Develop and implement algorithms for the simulation of fluid plasmas within complex magnetic edge topologies.
  • Conduct simulations and analyses of collisional edge plasma in stellarators, coupled with neutral-particle and atomic physics models.
  • Collaborate with cross-disciplinary teams to design stellarator divertor systems.
  • Perform data analysis, model validation, and provide insights into the physical mechanisms governing plasma behavior.
  • Prepare technical reports, presentations, and publications based on design, optimization, and simulation results.
  • Stay up to date with the latest advancements in computational plasma physics, fusion energy, and optimization techniques.
  • Requirements
