Job Description

As part of the Plant Operations organization, Utah Site Operations manages the day-to-day operation, maintenance, and readiness of Valar's Utah facilities.

Key Responsibilities

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.
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 thrive in a dynamic startup environment and can adapt to evolving priorities without losing sight of all tasks.
You take extreme ownership of operational programs and can collaborate across disciplines to drive results.
You are willing to learn the regulatory frameworks that govern nuclear technology and ensure industry standards are implemented and fulfilled.
You hold a high bar for operational safety, can serve as a credible technical authority, and envision pathways for continuous system improvement.
You can identify and tackle problems wherever they arise, from analytical modeling and program development to shop-floor troubleshooting and hands-on labor.
You can communicate findings coherently and tailor reports to interface with technical authorities, regulatory reviewers, and the skilled trades workforce.
