Job Description

Commonwealth 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.


As an Electro-Mechanical Engineer for the SPARC RF heating system, you will perform thermal, structural, and electromagnetic analysis using hand calculations and finite element method. You will develop design notes, technical specifications, assembly procedures and documentation necessary to prototype, manufacture, commission and install the RF components in Devens, MA. In your role you will also support procurement in the preparation and execution of manufacturing contracts. In addition, CFS will embark on significant internal assembly, commissioning and integration tasks that will require electro-mechanical engineering activities.


This work is conducted within a multi-disciplinary team of physicists and engineers.
