Intern - Plasma Physics - Summer 2027

About Commonwealth Fusion Systems: Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy. Combining decades of research, top talent, and new technologies, we’re designing and building commercially viable fusion power plants. And we're working with policymakers, suppliers, and many others to build the energy industry of the future. We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world. Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team. If that’s you and this role fits, we want to hear from you. Join the power movement as a Plasma Physics Intern The plasma physics department at CFS is looking for a summer intern to join the plasma digital twin team for 2027. We encourage both undergraduate and graduate applicants, as this internship will be tuned to match the candidate’s current skill set and education level. This internship will consist of 1-2 projects, selected from several potential project options by the intern at the onset of the internship. Given the recent advancements with LLMs and agentic AI, projects that address questions at the intersection of AI and physics are likely. Students studying all branches of plasma physics are encouraged to apply, as well as students with backgrounds applying machine learning or AI to physics problems.
