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 and suppliers to build the energy industry of the future.
We’re in the best position to make it happen. Since 2018, we’ve raised nearly $3 billion in capital, making us the largest and leading private 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 Director, Materials and ProcessingThe Materials and Processing (M&P) Department at CFS supports design engineers, supply chain,and manufacturing by selecting materials, unambiguously defining materials and processing routes,validating and measuring those materials and their properties, and conducting R&D to develop new materials and processes to enable fusion power deployment. M&P at CFS is organized around threeprimary thrusts: engineering, test and characterization, and the fusion materials development program. 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 devicespose unique materials challenges including neutron fluxes produced by deuterium-tritium fusion, high heat loads, molten salt coolant systems, complex component topologies, high magnetic fields, andhigh mechanical loading in cryogenic conditions.
We are seeking a dynamic and technically accomplished leader for materials and Processes. In thisrole, you will be responsible for the strategic direction of M&P and tactical operation of a corediscipline required for fusion development and deployment. The team includes matrixed coreengineering resources deployed for product development and de-risking, ~1000 sqft and >$5M of hands-on characterization and process development infrastructure, and world-expert scientific staff responsible for a fusion power plant materials development roadmap.
You will represent the discipline in core, company-level decision making and strategy setting, defining problems for cross-functional teams. Reporting through the Director of Technology Development, you will work with other disciplinedirectors to operationalize the company’s technology roadmap to fusion power plant deployment.
