About The Position

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 are designing and building commercially viable fusion power plants. Since 2018, we have raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world. The Staff Multiphysics Modeler will work closely with the CFS tritium program and process engineering team to develop a fuel cycle model for the world's first fusion power plant, ARC, located in Chesterfield County, Virginia. This role involves developing simulation toolkits and workflows that integrate first-principles multiphysics simulations with industrial process models to support technology development and subsystem integration for key fuel cycle systems. The ideal candidate is an expert in heat and mass transport modeling, with an appreciation for simplicity and drive to build, and enjoys teaching and building tools that others can use independently.
