Nuclear Operations Engineer

About Valar Atomics At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable—unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level. The Team As part of the Plant Operations organization, Utah Site Operations manages the day-to-day operation, maintenance, and readiness of Valar's Utah facilities. The team supports safe, reliable site operations while enabling successful project execution. The Role As an Nuclear Operations Engineer , you will design and execute structured engineering test programs for reactor components, control systems, and integrated plant operations. You will develop test plans, determine experimental conditions, analyze complex data sets, and generate engineering-level conclusions that inform plant performance, safety margins, and design evolution. Key Responsibilities Design engineering test plans for first of a kind reactor systems, subsystems, and control algorithms Establish experimental conditions, analytical models, acceptance criteria, and evaluation methods Conduct highly instrumented reactor and component test campaigns in collaboration with operations teams Analyze complex thermal, structural, neutronic, and control data; interpret trends and anomalies Develop engineering reports, test summaries, and recommendations for engineering change proposals Serve as technical authority for experimental methods and test safety reviews Provide input into reactor system design, safety cases, and operating envelopes Evaluate fuel performance, system reliability, and stability margins during commissioning Collaborate cross-functionally with design engineering, safety analysis, operations, and materials science teams Author engineering procedures, test standards, and research documentation Present findings to technical leadership, independent reviewers, and regulatory interfaces Support plant operations and maintenance as needed You Will Be Successful in This Role If You thrive in a dynamic startup environment and can adapt to evolving priorities without losing sight of all tasks.
