Intern - Mechanical / Manufacturing Engineer - Summer 2025

Devens, MAInternships / Full-time / On-siteCommonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.

CFS collaborates with MIT to leverage decades of research combined with groundbreaking new high-temperature superconducting (HTS) magnet technology.

HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible.

To that end, CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution.

Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change.

To implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.

We are looking for talented technical interns to join our team! CFS interns are highly valued within the organization and placed into meaningful and challenging roles.

Program Details :

• 12-16 week internship program
