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.\nWhat you'll do:\nTranslate 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\nIdentify 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\nSelect and interpret applicable international materials standards and specifications, and author materials specifications for fusion-specific applications\nServe as a technical lead for materials development projects when commercially available materials do not meet application requirements\nCollaborate with design, supply chain, and manufacturing engineers to select, approve, and qualify materials and processing methods\nProvide on-demand subject matter expertise for production root cause analyses and corrective action plans involving raw or as-fabricated materials\nReview, interpret, and report materials property data in version-controlled databases for engineering use\nWhat we’re looking for:\nMaster’s degree with post-graduate experience in metallurgy, materials science, or a related discipline. Depending on experience and qualification, a bachelor’s degree will also be considered\nMinimum of 10+ years experience\nExperience with large-scale metal production processes, such as casting, forging, rolling, and drawing, and/or large-scale joining processes, such as soldering\nExperience collaborating and communicating effectively with technical teams at vendors and suppliers\nFamiliarity with scaling metal and alloy design and development from R&D to full-scale products.\nStrong understanding of process-structure-properties-performance relationships in materials.\nKnowledge of materials behavior in cryogenic and high-temperature applications, and the effects of nuclear and plasma environments is a plus\nStrong problem-solving skills, with the ability to approach new and under-defined problems with creativity.\nExperience with agile project management and effective task execution\nAbility to work effectively in a multidisciplinary team of engineers, scientists, technical staff, and other stakeholders\nAbility to operate effectively within a flexible, service-oriented engineering organization\nBonus points for:\nDemonstrated success in delivering new alloys or materials processes from design and development through at-scale implementation\nExperience authoring materials standards and specifications\nExperience communicating materials design and development approaches, results, and performance metrics to both technical and executive leadership\nDemonstrated ability to make and justify materials and engineering decisions in fast-paced development and production environments\nDemonstrated ability to take under-defined problems and drive them to completion\nMust-have Requirements:\nPerform activities such as typing and sitting for extended periods of time\nDedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics\nWillingness to travel or work required nights/weekends/on-call occasionally.
