Materials Engineer

About the Role

You will play a key role in developing the material foundations that enable Hadron’s reactors to achieve reliability, longevity, and manufacturability at commercial scale—bridging the gap between material science innovation and practical engineering application. The Materials Engineer will support the design, testing, and qualification of structural and functional materials used in Hadron Energy’s micro modular reactor (MMR) systems. This individual will collaborate with nuclear, mechanical, and thermal engineers to ensure materials meet performance, safety, and regulatory requirements under high-temperature, radiation, and corrosive environments. • Research emerging materials technologies applicable to nuclear and energy systems (e.g., ceramics, composites, advanced steels) • Contribute to the design of radiation-tolerant and corrosion-resistant materials for reactor and balance-of-plant systems • Interface with suppliers, laboratories, and research institutions to source and validate advanced materials and coatings • Conduct material property analysis, testing, and characterization, including tensile, creep, fatigue, and corrosion testing • Lead material selection, evaluation, and qualification for components operating under nuclear, thermal, and mechanical stress conditions • Support component and subsystem testing programs, analyzing results and recommending design or process improvements • Develop and maintain material databases, specifications, and test plans in alignment with ASME, ASTM, and NRC standards • Collaborate with QA and regulatory teams to ensure material traceability, documentation, and quality compliance • Support the development of welding, joining, and fabrication processes for high-temperature alloys and pressure-boundary materials • Collaborate with design and structural teams to ensure materials meet performance, safety, and lifecycle requirements
