Combination Welder

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.

 The Materials Department at CFS supports design engineers, supply chain, and manufacturing by selecting materials and processes, unambiguously defining materials and processes, validating and measuring those materials and their properties, and conducting R&D to develop new materials and processes to enable fusion power deployment. The work is undertaken in support of delivering SPARC, the net energy tokamak under construction in Devens, MA, and ultimately in designing the ARC fusion power plant. These devices pose unique materials challenges including neutron fluxes produced by deuterium-tritium fusion, high heat loads, molten salt coolant systems, complex component topologies, high magnetic fields, and high cryogenic mechanical loads. To support this mission, the CFS Materials Department is seeking a combination welder to support the welding engineering team. This team supports welding process development for both in- and out-of-house superconducting magnet and tokamak assemblies. The welding engineering team works collaboratively across disciplines to develop weld geometry and techniques, weld specifications, and inspection methods needed for CFS components.
