•$68,325 - $104,385

About The Position

The Mechanical Designer 3 performs mechanical design for special-purpose, one-of-a-kind equipment, including gloveboxes, precision furnaces, hot cells, custom pressure vessels, and associated controls and auxiliary systems. Under the direction of the Mechanical Project Lead, the designer develops drawings and 3D CAD models for multidisciplinary projects, resolves a variety of mechanical design issues, and uses 2D and 3D CAD tools to produce design packages. The role includes coordinating detailed design phases across an integrated design model, supporting other designers and project team members, and independently planning and producing design deliverables such as general arrangements, piping isometrics and composites, pipe support drawings, and equipment location drawings. The designer may accompany and assist other designers and engineers on field walkdowns and data gathering at client facilities. The position also includes sharing knowledge through Sargent & Lundy’s processes and Communities of Practice, and guiding less-experienced designers and drafters. The position supports Sargent & Lundy’s Government Services Division, which provides engineering design and consulting support to U.S. Department of Energy sites, national laboratories, and the National Nuclear Security Administration.
