Intern - Electromagnetic Engineer - Summer 2025

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 working with policymakers and suppliers to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.

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 an Electromagnetic Engineer Intern

CFS is seeking an Intern with knowledge in Computational Electromagnetics and Finite Element Analysis of Magnet systems.

Program Details:

• 12-16 week internship program
• 40-50 hours per week with set hourly salary based on year in school
• Opportunity for this position is in Devens, MA. If an intern is going to be on site, you will be responsible for your own transportation and housing
• Specific project assignments and required technical skillset will vary based on the team’s existing need.
• Opportunities available for currently enrolled college students in all levels of schooling from bachelor’s degree to PhD
• Interns must be authorized to work in the United States for any employer

What you'll do:

• Perform FEA simulations, magnetic field analysis of highly non-linear, anisotropic systems utilizing both commercial as well as in-house finite element simulation tools
• Customize FEA tools though scripting (Python/C++ etc.) as needed

What we’re looking for:

• Master’s or PhD Student in Electrical Engineering, Seniors with experience
• Requirements: Applied Physics (engineering)
• Strong background and theoretical understanding of computational electromagnetic models and electromagnetic fields is required;
• Experience with commercial FEA tools like COMSOL is a plus
• Ability to customize FEA tools using scripting tools like Python/MATLAB/C++ is a plus
• Ability to perform multi-physics coupling simulations (coupling heat transfer and solid mechanics physics)
• Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics

Essential Requirements:

• Willingness to travel or work required nights/weekends/on-call occasionally
• Perform activities such as typing, standing, or sitting for extended periods of time
• Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
• #LI-Onsite
