Manager, Nuclear Operations

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  We're seeking an Operations Manager to lead the day-to-day operations of one of the most advanced nuclear and fuel systems ever built. This is a hands-on leadership role responsible for guiding reactor and fuel plant operators, managing radiation safety and compliance, and ensuring operational excellence across all systems and shifts. You'll oversee both the reactor plant and the pilot TRISO fuel fabrication facility, ensuring smooth, safe, and efficient operation of all site activities—from startup and commissioning through steady-state operation and production.

This position is based at the Orangeville, Utah pilot facility, with periodic travel to Valar Atomics' Los Angeles headquarters for coordination, training, and integration with engineering and design teams. At Valar, we believe in shared ownership of the mission, and as Operations Manager you'll model a culture of teamwork, accountability, and continuous improvement.

Oversee daily operations of advanced high-temperature reactor systems and TRISO fuel fabrication processes.
Manage radiation protection, safety, and environmental compliance programs in coordination with EHS and regulatory teams.
Develop, implement, and maintain operating procedures, training programs, and qualification standards for plant personnel.
Plan and manage budgets, staffing, and scheduling for operational activities and maintenance.
Support commissioning, startup, and performance testing for both reactor and fuel systems.
Monitor and analyze operational data to ensure efficiency, reliability, and adherence to performance goals.
Coordinate cross-functional efforts between engineering, quality assurance, and regulatory teams.
Promote a culture where everyone steps up to meet the most critical needs to ensure safe and successful operation.
You Will Be Successful in This Role If   You're a hands-on leader with a deep understanding of complex technical systems and process operations.
You build and mentor high-performing operational teams, raising the technical capability and safety culture of the group over time.
You hold a high bar for safety, precision, and continuous improvement across every shift and every system.
You thrive in a startup environment where priorities evolve and collaboration across disciplines is essential.
You make sound decisions under operational pressure, balancing throughput, safety, and reliability.
You take ownership of the end-to-end operation, from procedures and training through performance monitoring and cross-functional coordination.
