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 worlds 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.
SPARC will sustain fusion reactions by feeding >25MW of RF power into the tokamak to heat the plasma to 100 million Kelvin. We need an outstanding RF engineer to build the most powerful Ion Cyclotron Resonant Heating (ICRH) system in the world.
Your responsibilities will include modelling, integration, test, and troubleshooting of all elements of the SPARC RF antenna system.
