Mechanical Engineer 3 - Nuclear
About The Position
Join Sargent & Lundy's Nuclear Power Group and be part of a team driving the future of clean, carbon-free energy. Since 1954, we’ve been a trusted leader in nuclear engineering, design, and licensing, with expertise spanning small modular reactors (SMRs), advanced reactor technology (ART), and first-of-a-kind commercial reactor restart projects. Our work supports life extensions and digital modernization of existing nuclear plants, coal-to-nuclear conversion initiatives with the Department of State, and international nuclear new-build projects. With a commitment to safety, innovation, and sustainability, we provide cutting-edge solutions that power communities worldwide while reducing emissions. Shape the future of global energy with us! In this role, we expect people to be willing or able to solve problems using modern tools: You are expected to take engineering problems from issue to solution using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs. Many engineers in these roles build or use automation to create calculations, summarize technical documents, or draft design documentation, including appropriate use of agentic AI tools, with strong engineering judgment and verification of results.
