• Contribute to the development and validation of simulation tools for divertor and boundary plasma physics
• Support integrated core-edge modeling and analysis to evaluate plasma performance and stability
• Model a range of plasma phenomena, including:
• • Neoclassical transport
  • Energetic particle transport
  • Plasma-neutral interactions and boundary physics
  • MHD equilibrium and stability
  • Pellet fueling
  • Electron cyclotron heating (ECH)
• Collaborate cross-functionally with engineering teams to provide physics-based insights that inform system design and optimization
• Analyze simulation outputs and experimental data to validate models and improve predictive capability
• Document findings through technical reports, presentations, and peer-reviewed publications

What you'll need:

• PhD in Plasma Physics, Computational Physics, Nuclear Engineering, or a related field
• Strong background in plasma physics theory and numerical simulation methods
• Experience with one or more of the following:

Gyrokinetic simulation codes
MHD equilibrium and stability tools

• Experience with data analysis and visualization tools
• Demonstrated ability to work in collaborative, multidisciplinary teams

Preferred Qualifications

• Experience with stellarator physics and optimization
• Familiarity with core-edge coupling and integrated simulation workflows
• Prior involvement in fusion experiments or large-scale simulation projects
• Track record of peer-reviewed publications in relevant fields

We offer:
In addition to a basic salary and yearly bonus, you will also get...

• A hybrid work policy
• Stock options
• Relocation allowance
• Insurance plans
• Retirement options
• And many more great voluntary benefits
