Exam Writer 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."

Nuclear Exam Writer
The Exam Developer will play a key role in designing and executing the licensing examination program for TerraPower's FOAK fast sodium reactor (FSR). This includes all Initial License Training (ILT) program examinations and Licensed Operator Continuing Training (LOCT) examinations, ensuring full compliance with NUREG-1021, 10 CFR Part 55, and future advanced-reactor guidance (e.g., NEI 23-01, NRC DRO-ISG-2301-1, DANU-ISG-2022-05).
A core element of this role is to develop and gain NRC approval of a customized Knowledge and Abilities (K/A) Catalog or equivalent competency framework tailored to fast sodium reactor technology, establishing the foundation for operator licensing, regulatory compliance, and long-term training program accreditation.
This individual will collaborate with internal reactor design, I&C, human factors, and training specialists-as well as external stakeholders such as the NRC-to ensure exam content validity, reliability, and traceability to plant systems and licensing requirements
Responsibilities

• Obtain and maintain NATRIUM Senior Reactor Operator (SRO) Certification.
• Develop and manage the Natrium licensing examination program in alignment with NUREG-1021, 10 CFR Part 55, advanced-reactor guidance (e.g., NEI 23-01, DRO-ISG-2301-1, DANU-ISG-2022-05), and all regulatory, accreditation, and QA requirements.
• Design and manage all ILT program assessments using the Systematic Approach to Training (SAT), aligned with task, K/A, and KSA analyses.
• Develops and administers periodic LOCT examinations-both written and simulator-to meet 10 CFR 55.59 requalification requirements.
• 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.
• Remain current on evolving NRC policies, advanced-reactor guidance, and industry best practices for exam development, validation, and program governance.

Key Qualifications and Skills Minimum

• Previous NRC Reactor Operator (RO) or Senior Reactor Operator (SRO) license or certification (license preferred); advanced-reactor or non-LWR experience a plus.
• Certified Nuclear Instructor (INPO) or equivalent, or the ability to obtain certification.
