Job description

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 and maintain reactor-specific Knowledge and Abilities (K/A) frameworks and catalogs, ensuring traceability to plant systems, procedures, design documents, and SAT-based training objectives. Develop, update, and validate written examinations, simulator operating tests, JPMs, LOCT examinations, and exam scenarios using validated exam-development methodologies (item analysis, psychometrics, difficulty balancing, and peer review). Maintain secure and accurate exam item banks, scenarios, and performance measures with strict confidentiality, version control, documentation standards, and auditable records. Collaborate with simulator engineers, instructors, operators, SMEs, and licensing personnel to ensure exam content reflects Natrium design features, human-system interface characteristics, operator tasks, and operating expectations. Coordinate with NRC examination and review staff to develop, submit, validate, and obtain approval for exam materials and K/A mappings; support audits, inspections, RFIs, and corrective actions. Analyze exam results, candidate performance data, operating experience, and feedback to continuously improve exam quality, validity, and integration with the overall SAT-based training and qualification program.
