Staff Materials Engineer - Metallurgical Engineering
Quick Summary
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,
The Materials Department at CFS supports design engineers, supply chain, and manufacturing by selecting materials, unambiguously defining materials and their properties, 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 Senior Materials Engineer with expertise in metals and alloys in both R&D and production environments.
- Translate component and system performance requirements and failure modes into verifiable critical material property requirements under manufacturing-relevant conditions, and define appropriate test methods to measure and validate those properties
- Identify materials and processes that enable the high-volume manufacturing of structures and systems under demanding operating conditions, with a focus on manufacturability, scalability, and cost consciousness
- Select and interpret applicable international materials standards and specifications, and author materials specifications for fusion-specific applications
- Serve as a technical lead for materials development projects when commercially available materials do not meet application requirements
- Collaborate with design, supply chain, and manufacturing engineers to select, approve, and qualify materials and processing methods
- Provide on-demand subject matter expertise for production root cause analyses and corrective action plans involving raw or as-fabricated materials
- Review, interpret, and report materials property data in version-controlled databases for engineering use
