Senior R&D Electromagnetic Analysis Engineer

Commonwealth Fusion Systems•Devens, MA

7d•Onsite

About The Position

Commonwealth Fusion Systems (CFS) is dedicated to accelerating the transition to fusion energy by designing and building commercially viable fusion power plants. The R&D team at CFS focuses on evaluating potential technical solutions to guide the design of the SPARC subsystem and plan for future fusion power plants and spin-off projects. The Electromagnetics Analysis Engineer will conduct electromagnetic (EM) analysis of superconducting magnets, including their non-linear, anisotropic behavior in various states. This role involves incorporating complex multi-physics system behaviors into simplified models and collaborating with experimentalists to validate simulations. Proficiency in commercial finite element analysis software and custom code development (Python) is essential. The position requires working within a multidisciplinary team, communicating effectively, and contributing to design and testing activities.
