Mechanical Engineer 3 - Nuclear

Sargent & Lundy•Knoxville, TN

10d•$74,353 - $113,595•Hybrid

About The Position

This role will offer a hybrid work arrangement from our future Knoxville office. The expectation will be to spend three days a week in the office, giving you the flexibility to work remotely for two days. You will be involved in nuclear power plant systems design, including preparation or review of modification packages for operating nuclear power plants, functional mechanical drawings and/or drawings for nuclear power plant systems, engineering analyses and evaluations to support modifications and operation of plant systems, technical specifications and procurement documents for plant equipment, vendor bid evaluations for plant equipment, and studies and options evaluations for modifications to operating nuclear power plants. In addition, you will have the opportunity to develop engineering cost estimates for small to mid-sized client-requested work scopes, visit client office and/or plant site locations to interface with the client and make presentations related to engineering tasks and status, and lead engineering project teams. 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.
