Full Job Description

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 Role Valar Atomics is seeking a Welding Engineer to lead the development, qualification, and production implementation of welding processes for advanced reactor systems, pressure vessels, high-temperature piping, structural assemblies, and fuel fabrication infrastructure. This role will be instrumental in establishing Valar's nuclear manufacturing capabilities from the ground up, including welding procedure qualification, supplier qualification, fabrication oversight, and development of scalable production methods for first-of-a-kind nuclear hardware. Responsibilities Develop and qualify welding procedures in accordance with ASME Section IX and applicable nuclear fabrication standards. Support fabrication and inspection of pressure vessels, reactor vessels, heat exchangers, piping systems, and pressure-retaining components. Collaborate with design engineers on weld joint design, material selection, and fabrication requirements. Establish weld maps, traveler documentation, traceability systems, and fabrication records required for nuclear-quality manufacturing. Support implementation of NQA-1 quality requirements and manufacturing controls. Interface with Authorized Inspectors, third-party inspectors, and regulatory stakeholders. Develop welding specifications for stainless steels, nickel alloys, carbon steels and advanced high-temperature m
