Senior Automation and Controls Engineer

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.

You will be joining Valar Atomics' Automation and Controls team within the Instrumentation, Control & Electrical (IC&E) organization. I&C Software Engineers own the logic and data layer PLC and DCS application code, ISA-88 batch sequences, SCADA and HMI applications, historian infrastructure, and enterprise integration across the reactor program and fuel manufacturing operations. You will work alongside I&C Hardware, electrical, process, and nuclear safety engineers in an environment that blends traditional control systems with modern software and data integration practice.

The team values operator-focused design, data integrity, disciplined documentation, and a safety-first culture.

Valar Atomics is seeking Senior Automation and Controls Engineers to develop, configure, test, and commission the control system software for our reactor and nuclear fuel manufacturing facilities. The role covers PLC and DCS programming, SCADA and HMI application development, ISA-88 batch control, alarm management, safety logic programming, historian configuration, and ISA-95 enterprise integration supporting both capital projects and ongoing plant operations.

This is a senior position: you will own controls software scope end-to-end, from functional specification through commissioning and long-term support, and provide technical direction to contractors, vendors, and junior engineers.
