Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.

CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. The mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. To execute this plan, we are looking to add talented people to the team who are mission-driven and treat people well, improve our team by adding diverse perspectives and new ways of solving problems, have demonstrated exceptional results through a range of different pursuits, and have skill sets and experience that relate to this role.

CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. The ARC power plant will be the first machine to produce electricity from fusion energy, serving as the cornerstone to a new industry. The ARC group within R&D is a growing team that is delivering key scientific and engineering results to push the TRL of enabling technologies (blanket systems, materials, power conversion, etc.) higher. To execute this plan, we are looking to add talented people to the team who are mission-driven and treat people well, improve our team by adding diverse perspectives and new ways of solving problems, and have demonstrated exceptional results through a range of different pursuits.

The materials and manufacturing team within ARC R&D has openings for several roles aimed at meeting the challenges of a fusion power plant. Neutron fluxes produced by deuterium-tritium fusion, high heat loads, molten salt coolant systems, and complex component topologies all introduce unique challenges for optimizing material selection while meeting manufacturing and cost requirements. ARC R&D will work closely with the ARC Design team to downselect materials and design ARC components for steady state fusion power output. We are seeking experimental and computational materials experts in the following areas: Structural material qualification and testing for radiation environments; Plasma facing materials and plasma-material interactions; Advanced manufacturing and joining for high temperature and nuclear components; and Molten salt corrosion and mitigation

This team member will:

- Lead testing and qualification of materials and components for structural and functional applications within ARC
- Translate performance requirements into material property specifications and define appropriate test methods
- Coordinate the design, fabrication, installation, operation, and analysis of experimental systems in-house and in collaboration with partners at Universities, National Laboratories, and Industry
- Ensure efficient and timely transfer of property data and new insight to the ARC Design team 
- Identify appropriate manufacturing and joining technologies for ARC components and systems, develop test plans to vet such technologies 
- Work closely with other CFS teams including: safety team to manage chemical/mechanical/environmental hazards in existing and New experimental facilities, adjacent R&D teams to optimally share pooled resources including equipment and personnel, supply chain team to procure new equipment and materials, manufacturing team to ensure fabrication methods are scalable, provide technical guidance to project team members to ensure efficient execution of design-build-test-learn cycles and retirement of technical risks

The ideal candidate will have most, if not all, of these requirements:

- PhD in Materials Science, Mechanical Engineering, Nuclear Engineering or a related field _or _BS with 5 years of relevant experience 
- Experience leading/coordinating materials R&D projects from conception to execution 
- Familiarity with nuclear and plasma effects on material properties and performance
- Experience with utilizing University, International/National Laboratory, and/or outsourced testing and research organizations
- Ability to work effectively in a multidisciplinary team of engineers, scientists, technical staff and others
- Ability to clearly express and critique ideas
- Great communication and organizational skills 
- Strong problem solving skills, ability to approach new problems with creativity
- Resource estimation and projection 
- Strong time management skills 
- Self - motivation and autonomy

Additional experience and/or qualifications:
- Ability to perform activities such as typing and sitting for extended periods of time

CFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits. We all tightly align with our company values of integrity, execution, impact and self-critique. As we grow, we are looking to add talented people who are mission driven and bring diverse perspectives and new ways of solving problems.
