Burning Plasma Scientist

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 a highly motivated Burning Plasma Scientist to join our Physics team, focusing on modeling energetic particle confinement and transport. In this role, you will run high-fidelity simulations and pioneer the use of Machine Learning surrogates to accelerate our design cycles. You will work directly with our optimization team to ensure our magnetic topologies manage fast-ion loss and heat loads effectively.

• Execute and analyze high-fidelity simulations using particle-following codes to assess alpha particle and neutral beam ion confinement in 3D magnetic geometries
• Investigate Alfvén Eigenmode (AE) stability using kinetic-MHD hybrid codes and assess their impact on energetic particle transport
• Develop reduced-order models and ML surrogates trained on simulation databases to enable real-time prediction of pressure profiles
• Collaborate with the engineering team to iterate on coil designs and divertor configurations to minimize fast-ion losses
• Develop synthetic diagnostics (e.g. Fast-Ion Loss Detectors, Neutron Cameras) to bridge the gap between our models and future experimental campaigns

• PhD in Plasma Physics, Computational Physics, or related field (or Master’s / Bachelor’s with equivalent research experience)
• Proficiency in programming languages commonly used in scientific computing (e.g. Python, Fortran, C++, or MATLAB)
• Creative problem solving and proven ability to thrive in collaborative environments such as startups or research groups
• Willingness to collaborate with a diverse team of scientists and engineers within the company and externally
• Passion for advancing the field of fusion energy research
• 
  
• Familiarity with kinetic, MHD or particle-following codes
• Experience developing Machine Learning surrogates for physical systems
• Familiarity with energetic particle diagnostics

• Salary range $135,000-$210,000
• Comprehensive health benefits (e.g. medical/dental/vision)
• Employee equity stock options
• 20 days PTO

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. By creating a diverse environment, we will bring new ideas and approaches to solving some of the world’s hardest (and most important) problems.
