Who We Are Looking For We are looking for an experienced Senior Mechanical Designer who enjoys solving complex design challenges and turning ideas into practical, buildable equipment. You take skid-based, modular and containerized systems from concept through detailed 2D and 3D design and release for fabrication, working mostly in SolidWorks and AutoCAD. Whether your experience comes from custom machinery, industrial equipment, automation, manufacturing or process systems, you develop design solutions that balance function, manufacturability, safety, cost and schedule. You are comfortable working directly with clients. You communicate clearly, ask the right questions, and turn their input into clear, documented project requirements the team can build from. You take ownership of technical work, collaborate closely with engineers and fabrication teams, and share your knowledge with less experienced designers. This is a chance to lead challenging design projects and help shape our design standards while staying hands-on. This position is based onsite in Rochester and/or Rush, NY, with occasional travel to customer and supplier locations, typically less than 25%. What You Get To Do Lead mechanical design of custom equipment, skid-mounted and modular systems, and industrial machinery from concept through release for fabrication. Develop 3D models and 2D drawings including layouts, assemblies, weldments and components in SolidWorks and AutoCAD. Produce general arrangement drawings, equipment layouts, fabrication and assembly drawings, and bills of material using GD&T, weld symbols and drafting standards. Solve complex mechanical design challenges while considering performance, safety, manufacturability, and cost. Collaborate with mechanical, electrical, controls, and manufacturing teams to develop integrated equipment and system designs. Lead technical design reviews, evaluate design solutions, and provide guidance to project teams and customers. Partner with fabrication and assembly teams to resolve technical challenges and support successful equipment builds and installations. Support project planning, technical proposals, and engineering estimates. Mentor junior designers and drafters, providing technical guidance and reviewing design work. Improve design standards, tools, and processes to enhance quality, consistency, and efficiency. What You Bring To The Team <span data-ccp-props="{"13424
