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 a Staff Materials Engineer - Metallurgical Engineering
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.
What you'll do:: 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
What we’re looking for:: Master’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
Minimum of 10+ years experience
Experience with large-scale metal production processes, such as casting, forging, rolling, and drawing, and/or large-scale joining processes, such as soldering
Experience collaborating and communicating effectively with technical teams at vendors and suppliers
Familiarity with scaling metal and alloy design and development from R&D to full-scale products.
Strong understanding of process–structure–properties–performance relationships in materials.
Knowledge of materials behavior in cryogenic and high-temperature applications, and the effects of nuclear and plasma environments is a plus
Strong problem-solving skills, with the ability to approach new and under-defined problems with creativity.
Experience with agile project management and effective task execution
Ability to work effectively in a multidisciplinary team of engineers, scientists, technical staff, and other stakeholders
Ability to operate effectively within a flexible, service-oriented engineering organization
Bonus points for:: Demonstrated success in delivering new alloys or materials processes from design and development through at-scale implementation
Experience authoring materials standards and specifications
Experience communicating materials design and development approaches, results, and performance metrics to both technical and executive leadership
Demonstrated ability to make and justify materials and engineering decisions in fast-paced development and production environments
Demonstrated ability to take under-defined problems and drive them to completion
Must-have Requirements:: Perform activities such as typing and sitting for extended periods of time
Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
Willingness to travel or work required nights/weekends/on-call occasionally. Travel less than 10%
At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.
We value diversity deeply and are proud to be an equal opportunity employer by choice. We consider all qualified applicants equally, regardless of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law.
This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, “Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.
