System One is seeking a highly motivated Materials Engineer (Weld) to support the engineering efforts of the Materials Development and Qualification team. This role will join a high-functioning team focused on weld processes, supply chain development, and supplier qualification for next-generation materials and components for sodium-cooled fast reactors.
You will support weld development activities ranging from fundamental laboratory testing to manufacturing process development for advanced reactor components. A primary function of this role is applying metallurgical fundamentals and weld engineering requirements to inform manufacturing process development in collaboration with external suppliers.
Responsibilities- Partner with cross-functional project teams to provide welding configuration, geometry, and methods guidance supporting reactor development programs
- Develop weld designs, specifications, and processes to support reactor design and licensing using fundamental welding engineering principles
- Inform materials test programs to validate material/weld performance models and ensure testing aligns with Natrium reactor program objectives
- Perform scientific analysis of test data (e.g., metallography, NDE, mechanical properties, ductility) and generate technical reports
- Provide materials engineering support for procurement of engineered components/systems, including leading supplier technical development to increase technology readiness levels
- BS + 3 years related experience, MS + 2 years, or equivalent experience
- Degree in Materials Science/Engineering, Welding Engineering, or related discipline (preferred)
- Experience with weld engineering for new design
- Experience defining weld geometries, methods, and property impacts for welded pipes, pressure vessels, and equipment
- Strong understanding of metallurgy, including welding and heat treatment of ferrous (austenitic / ferritic-martensitic steels) and nonferrous (nickel-base) alloys
- Ability to work with minimal direction and solve challenging problems
- High degree of trust and integrity; strong communication and teamwork skills
- Working knowledge of ASME NQA-1 and ASME Section IX (highly desirable)
- Understanding of weld design/parameter impacts on complex mechanical phenomena (creep, fatigue, creep-fatigue, SCC, fracture) in high-temperature systems
- Experience qualifying welds for service in highly regulated applications
