Senior Director of Physics Analysis

Type One Energy is seeking Computational Physicists to contribute to the development of high‑fidelity models and simulations supporting stellarator design and operation. These roles will focus on predictive modeling of plasma behavior across core, edge, and boundary regions, enabling data‑driven design decisions and advancing fusion performance.

This is an opportunity to work at the intersection of theory, simulation, and engineering, contributing directly to the realization of commercial fusion energy.

You will work closely with Engineers and Scientists and will also be responsible for:

• Developing and executing integrated modeling frameworks to simulate and predict plasma operational scenarios
• Performing plasma profile and fusion performance predictions using gyrokinetic turbulence simulations and reduced models
• Contributing to the development and validation of simulation tools for divertor and boundary plasma physics
• Supporting integrated core‑edge modeling and analysis to evaluate plasma performance and stability
• Modeling 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)
• Collaborating cross‑functionally with engineering teams to provide physics‑based insights that inform system design and optimization
• Analyzing simulation outputs and experimental data to validate models and improve predictive capability
• Documenting findings through technical reports, presentations, and peer‑reviewed publications

• 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
  • Edge/divertor modeling simulation code experience
  • Integrated modeling codes
• Proficiency in scientific programming (e.g., Python, C++, Fortran) and high‑performance computing (HPC) environments
• Experience with data analysis and visualization tools
• Demonstrated ability to work in collaborative, multidisciplinary teams

• 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

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