About the role

About Commonwealth Fusion Systems:    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’re designing and building commercially viable fusion power plants. And we're working with policymakers, suppliers, and many others to build the energy industry of the future.   We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world.   Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.    If that’s you and this role fits, we want to hear from you. Join the power movement as an Senior R&D Test Engineer The role of an Senior R&D Test Engineer is to develop novel fluid systems for R&D test stands, with a major focus on supporting magnet testing. The range of process fluids is broad (liquid, gaseous, cryogenic, supercritical, molten salt, etc.), requiring strong mechanical and chemical engineering fundamentals. The ideal candidate will be resourceful—combining industry best practices, off-the-shelf and customized hardware, and creativity to deliver these fluid systems on tight timelines. Projects will be on varying scales, from smaller-scale test stands and deep system analysis to larger, complex projects as needed for SPARC and ARC. In addition to designing and building, the engineer will actively operate as a test engineer to commission systems and design automation alongside a team of test/software engineers and operators. You must work collaboratively across production, R&D, procurement, and the SPARC team. Various projects will also require flexing outside of traditional fluids engineering into other disciplines, such as structures and materials engineering, to successfully retire risks for SPARC and ARC.
