Senior Mechanical Designer

SPM Automation develops advanced plastic joining and custom automation solutions for leading global manufacturers. Proudly based in Windsor, Ontario, our expertise spans laser, infrared, hot plate, vibration, and ultrasonic welding bringing together applied science, machine design, and intelligent controls to solve demanding production challenges for customers around the world.
We build more than machines -we build long-term customer partnerships. By working closely with customers to understand their products, processes, and goals, we turn complex manufacturing problems into practical innovations that improve quality, productivity, and reliability.
At SPM, you can make a direct contribution and see the results. Our researchers, designers, controls specialists, and machine builders work side by side, connecting ideas and engineering decisions to equipment on the shop floor and performance in customers’ facilities.
As we grow, we are investing in our people and strengthening how we workbysharing knowledge, developing technical capability, and continuously improving our processes. We are looking for people who take pride in their craft, bring curiosity to difficult problems, and want to help customers and teammates succeed.
The OpportunityDesign it. See it built. Help make it better.
We are seeking a Senior Mechanical Designer who wants to own the outcome-not just complete the design.
You will lead the mechanical design of plastic welding machines and industrial automation equipment within agreed customer requirements, project scope, schedules, and engineering-hour budgets. Your involvement will extend from machine concepts and customer reviews through detailed design, assembly support, debugging, and equipment validation.
Working directly with engineering colleagues and the technicians building the equipment, you will turn design concepts into practical, reliable machines. You will also provide project-level design leadership, mentor colleagues, and help improve the tools and processes we use from one project to the next.
This full-time, on-site position is based in Windsor, Ontario, and reports to the Mechanical Engineering Manager. The role provides technical and project leadership but has no direct reports.
