TITLE: Materials Engineer, MCFR LOCATION: Bellevue, WA, USA TerraPower is a nuclear technology company based in Bellevue, Washington. At its core, the company is working to raise living standards globally through a more affordable, secure and environmentally friendly form of nuclear energy along with innovations in medical isotopes to improve human health. In 2006, TerraPower originated with Bill Gates and a group of like-minded visionaries who evaluated the fundamental challenges to raising living standards around the world. They recognized energy access was crucial to the health and economic well-being of communities and decided that the private sector needed to take action and create energy sources that would advance global energy deployment. TerraPower's mission is to be a world leader in new nuclear technologies, while developing innovators and future leaders in the nuclear field. As a result, the company's activities in the fields of nuclear energy and related sciences are yielding significant innovations in the safety and economics of nuclear power, hybrid energy and medical applications - all for significant human health benefits. TerraPower is seeking highly motivated and forward-thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes. Materials Engineer (Engineer, Senior Engineer, Principal Engineer), MCFR TerraPower, LLC is seeking a highly motivated Materials Engineer (level to be determined based upon qualifications - Engineer, Senior Engineer, Principal Engineer) to support the engineering efforts of the MCFR Materials Engineering team. This role will be a part of a high functioning team of engineers focused on materials engineering challenges for next generation materials and components for molten chloride fast reactors. You will be an integral part of the MCFR program, providing valuable materials insight and supporting/justifying plant level decisions on material selection through developing a thorough understanding of candidate materials in this extreme environment. Work developing and qualifying the materials' mechanical properties, corrosion, corrosion-erosion and environmentally assisted degradation responses, and irradiation behavior are some of the main foci of the team. You will interface and work closely with the test engineering, radiochemistry and mechanical design teams at TerraPower. Responsibilities * Plan and oversee material testing campaigns for candidate molten chloride fast reactor materials with external partners and collaborators * Evaluate and analyze material testing and characterization data in order to provide inputs for reactor design * Develop test requirements, plans, specifications, and procedures for testing metallic materials in high temperature molten salt environments and under irradiation * Assist in the planning of and participate in test programs for environmentally assisted degradation of candidate materials (e.g. corrosion, stress corrosion cracking, irradiation assisted degradation, environmentally assisted fatigue, creep, etc.) * Interface with project teams (mechanical design, testing, radiochemistry, etc.) to ensure material development and testing efforts meet program objectives * Work in cooperative projects for material testing and development with external collaborators, partners, and suppliers * Maintain project schedule and timely delivery of results to internal and external project stakeholders * Conduct testing and material characterization in a laboratory environment * Provide materials engineering support for the procurement of engineered components and systems * Assist in the procurements of materials, equipment, and testing services, including authoring procurement re
