If you are searching for the best new ideas and share our vision, join us for a “Summer Internship- Computational Physics”. This is what you need to know:

Location: Knoxville, TN

Salary: $25 per hour, 40 hours per week

Contract: 12 week contract- Summer 2026 (June 1st Start Date)

Reporting to: Senior Scientist

Your role in the mission:

Type One Energy is seeking a motivated and technically capable Computational physicist Intern to support our work in stellarator divertor physics. The successful candidate will contribute to simulation and modeling efforts aimed at improving our understanding of plasma behavior in our stellarator devices.

This internship provides a unique opportunity to gain hands-on experience with advanced computational tools, plasma physics modeling, and collaborative fusion energy research.

• Support development and execution of computational models focused on divertor physics and plasma–surface interactions in stellarator configurations.
• Perform data analysis and visualization of simulation results to extract key physical insights.
• Contribute to code development, optimization, and validation using existing modeling frameworks.
• Collaborate with physicists, engineers, and computational scientists to integrate results into broader design studies.
• Document findings, prepare summary reports, and present results in internal meetings.
• Present your results in regular meetings with your supervisors, and in wider meetings with the Applied Physics team.
• Document your progress within the company’s documentation system.

What you’ll need:
 

• Currently undertaking a degree in computer science, physics, mathematics or a related field
• Excellent written and verbal communication skills.
• Proficiency in Python or Julia.
• Experience in writing unit tests and documenting code.
• Experience in using git and CI/CD pipelines is desirable.
• Experience with C++ or Fortran is desirable.
• Background in scientific computing, numerical optimization, machine learning and high-performance computing is desirable.
• Ability to work independently and closely with senior colleagues.

Type One Energy applies proven advanced manufacturing methods, modern computational physics and high-field superconducting magnets to develop its optimized stellarator fusion energy system. Its FusionDirect development program pursues the lowest-risk, shortest-schedule path to a fusion power plant over the coming decade, using a partner-intensive and capital-efficient strategy.

Type One Energy is committed to community engagement in the development and deployment of its clean energy technology. For more information, visit www.typeoneenergy.com or follow us on LinkedIn.
