Nuclear Field Engineer Jobs (NOW HIRING)

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 to hire 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.

• Create formal documentation of nuclear methods software requirements, design, implementation, and testing in support of licensing TerraPower reactors.
• Update, improve, and/or create software to satisfy all licensing requirements during the Validation and Verification (V&V) process
• Incorporate additional 3rd-party programs in our simulation ecosystem as necessary to support licensing
• Design and execute sensitivity studies to understand the effects and validity of various modeling assumptions, including meshing, physics coupling, transport options, cross section preparation, fission product models, spatial kinetics, etc., and adjust methods as necessary
• Train and support reactor designers and developers in the use of the design software suite
• Build and apply methods to assess the propagation of uncertainty and their effect on safety margins
• Enhance engineering team's ability to build models and make meaningful conclusions from simulation output through input tools, visualization, reports, etc.,

Key Qualifications and Skills

• Ph.D. and 5+ years of experience in Nuclear Engineering or a related discipline from an accredited university, or a Master's degree with 8+ years of relevant experience
