Senior Mechanical Designer

As a Senior Mechanical Designer, you create detailed mechanical designs — 3D models, assemblies, and manufacturing drawings — that transform engineering concepts into buildable products. You're responsible for component sizing, material selection, tolerance specification, and ensuring designs can actually be manufactured. The senior title means you handle the most complex assemblies, make independent design decisions, and guide junior designers.

Your day centers on CAD and engineering judgment. You might model a complex mechanism in SolidWorks, run an interference check on a large assembly, specify fasteners and hardware for a structural connection, then work with manufacturing to resolve a fit issue discovered during prototype build. You need expert CAD skills, deep knowledge of manufacturing processes, and the mechanical intuition to know when a design will work before it's built.

The distinction from mechanical engineering is focus on detailed design rather than analysis. Engineers may calculate loads and specify requirements; you create the actual geometry that meets those requirements. The best senior mechanical designers combine engineering knowledge with practical manufacturing experience — they design things that are elegant on screen AND feasible on the shop floor.
