Senior Nuclear Supplier Quality Engineer

Valar Atomics is a nuclear energy company focused on scaling high-temperature gas reactors (HTGRs) for grid-independent industrial applications. The company is developing what it calls gigasites, large-scale facilities housing hundreds of nuclear reactors intended to power heavy industry, data centers, hydrogen production, and clean hydrocarbon fuel synthesis. Their reactor design uses TRISO fuel, a graphite moderator, and helium coolant, a combination the company highlights for its strong safety profile and proliferation resistance. By operating outside the traditional electricity grid, Valar Atomics aims to unlock economies of scale that have historically eluded the nuclear industry. Valar Atomics' mission centers on making nuclear energy the cheapest and most reliable energy source in the world, with a particular emphasis on decarbonizing industrial processes and enabling clean fuel production. Their hydrogen output, generated via a sulfur-iodine thermochemical cycle, can be combined with captured CO2 to produce synthetic hydrocarbons through a modified Fischer-Tropsch process, offering a pathway to drop-in clean fuels. The company also targets the surging power demands of AI data centers, which are projected to require over 200 additional terawatt-hours of grid power by 2030. The company is currently advancing its Ward 250 project, a test reactor being developed in partnership with the U.S. Department of Energy, the San Rafael Energy Research Center, and the State of Utah, with a target go-live date of July 4, 2026, America's 250th birthday. The reactor has already been physically transported to Emery County, Utah, with logistical support from the U.S. military. Four executive orders issued under the Trump administration provided a mandate supporting the project's accelerated deployment timeline.

The Team

As part of the Regulations & Safety organization, Quality Assurance establishes the systems and standards that ensure products and processes consistently meet the highest levels of quality and compliance. The team promotes continuous improvement and operational excellence across the company. 

The Role

As a Senior Nuclear Supplier Quality Engineer at Valar Atomics, you will serve as the nuclear quality assurance subject matter expert within the Supplier Quality organization. You will own the supplier oversight process, ensuring Valar Atomics’ supply chain is sound, robust, and defensible for the procurement of nuclear safety-related materials, components, and services.

You will lead the entire supplier auditing process, including planning, scheduling, execution, and reporting. Additionally, you will participate in other quality related processes including nonconformance reporting (NCR), supplier corrective action requests (SCAR), and tracking and trending activities, while interfacing directly with engineering, procurement, and construction project professionals.

You will play a central role in Valar Atomics’ Commercial Grade Dedication (CGD) Program. CGD is a  process by which commercial-grade items are evaluated and accepted for use in nuclear safety-significant applications without requiring a nuclear-grade procurement. Your two primary CGD responsibilities will be: (1) reviewing and approving all CGD Plans developed or revised by the Procurement Engineering group; and (2) serving as the primary technical point of contact for any CGD procurement that requires a Commercial Grade Survey—a supplier site visit and technical evaluation to verify that the item’s critical characteristics are controlled and acceptable.

This role demands clear critical thinking grounded in detailed knowledge of engineering principles and sound engineering judgment. A working knowledge of nuclear codes (e.g., ASME, AWS, AISC, welding, and NDE) along with applicable regulatory requirements and historical industry issues is essential. Professional conduct is required at all times.

Key Responsibilities

• Own and lead supplier quality activities across Valar Atomics’ safety-significant, quality-affecting, and nuclear-grade suppliers—including reactor components, fuel system hardware, specialty materials, instrumentation, fabricated assemblies, and special process providers.
• Participating in Valar Atomics’ Commercial Grade Dedication (CGD) program end-to-end: dedication methodology development, critical characteristics definition, technical evaluation plan construction, sampling strategy, CGD Plan review and approval, and Commercial Grade Survey execution.
• Plan, lead, and own nuclear supplier qualification programs, including supplier audit planning and execution, NQA-1 compliance assessment, process capability evaluation, documentation review, and formal qualification record development.
• Develop and maintain Valar Atomics’ nuclear supplier quality requirements framework, including purchase order quality clause libraries, NQA-1-aligned flow-down requirements, supplier quality plan standards, and source inspection criteria.
• Investigate and resolve complex or systemic nuclear supplier nonconformances using structured root cause and corrective action methodology, ensuring technically defensible outcomes with appropriate regulatory traceability.
• Develop and maintain supplier performance measurement systems, risk-tiered oversight frameworks, and supplier development programs for nuclear-grade and safety-significant suppliers.
• Support NRC, DOE, NNSA, customer quality representative, and external auditor engagements on supplier quality topics, including documentation preparation, technical interface, and finding resolution.
• Mentor Supplier Quality Engineers, contribute to organizational capability development on nuclear quality principles, and help institutionalize nuclear supplier quality disciplines across the team.
• Develop nuclear supplier quality procedures, CGD work instructions, qualification frameworks, and quality system documentation aligned with NQA-1 and applicable regulatory requirements.

You Will Be Successful In This Role If

• You operate as the nuclear quality authority in supplier quality engagements and are trusted by Valar Atomics Engineering, Procurement, and Regulatory organizations to make rigorous, defensible quality decisions.
• You understand and apply NQA-1 conservatively yet with a graded approach—driven by regulatory intent and probabilistic risk, not just checklists.
• You can distinguish between trivial and serious issues given regulatory intent and probabilistic risk analysis, and you recognize that sound engineering judgment is not always the most conservative answer.
• You can build nuclear supplier quality programs, CGD frameworks, and qualification systems from the ground up, in addition to operating within existing mature structures.
• You proactively identify systemic nuclear supplier risks and develop practical, scalable strategies to address them before they become program-impacting failures.
• You mentor and develop others effectively while maintaining strong personal execution discipline and nuclear quality ownership.
• You communicate with technical credibility and clarity across Engineering, Procurement, Operations, Regulatory, and supplier leadership.
• You believe rigorous nuclear quality and mission execution speed are complementary—and you know how to operationalize that belief in a fast-moving startup environment.
