Reporting to: Sr. RF Engineer

Your role in the mission:

As a Radio Frequency Engineering Intern, you will contribute to the design and development of electromagnetic (EM) systems and components for our fusion energy projects. Working alongside experienced engineers and physicists, you’ll gain hands-on experience diving into a complex and multi-faceted radio frequency (RF) project, leveraging EM analysis tools like ANSYS or COMSOL Multiphysics for 3D modelling, while learning about the technical challenges and tradeoffs inherent to RF design and development in a cutting-edge R&D environment.

Key responsibilities could include:

• Design RF and optical components using tools such as COMSOL and ANSYS
• Gain a deeper understanding of RF performance through a combination of analytical and numerical solutions
• Provide trade-off estimations using MATLAB or Python (or equivalent language)
• Work with Vector Network Analyzers to measure RF performance of components
• Assess multi-physics interactions such as plasma absorption characteristics or RF-based heating
• Contribute to design reviews and documentation to ensure accuracy and manufacturability
• Correlate analysis results with hand calculations, test data, or prototype inspection results.
• Collaborate with engineers across disciplines (mechanical, electrical, systems) to support ongoing development projects
• Participate in prototype fabrication, inspection, and testing as needed

What you’ll need:

• Pursuing a bachelor’s or master’s degree in Electrical Engineering or Radio Frequency Engineering
• Strong understanding of RF design fundamentals and principles
• Coursework or project experience with EM modelling using Ansys, COMSOL, AWR or equivalent solver
• Ability to critically evaluate simulation results, including checking for mesh convergence and reasonableness of boundary conditions
• Ability to work collaboratively in a fast-paced, multidisciplinary environment
• Strong attention to detail and solid problem-solving skills

Nice to have:

• Scripting experience (Python, MATLAB, or equivalent language) to automate or post-process simulation runs
• Familiarity with Electron Cyclotron Heating (ECH) principles for plasma

Type One Energy applies proven advanced manufacturing methods, modern computational physics and high-field superconducting magnets to develop its optimized stellarator fusion energy system. Our Fusion Direct 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  or follow us on Linked In.
