Sr. Mechanical Design Engineer

Pacific Bearing Co•Roscoe, IL

About The Position

Senior Mechanical Design Engineer – Pioneer the Future of Linear Motion PBC Linear, a recognized leader in linear motion innovation, is seeking a highly skilled Sr Mechanical Design Engineer to join our Product Engineering team. For over 40 years, PBC Linear has pioneered the industry, establishing leadership through developments like the self-lubricating plain linear bearing. We are a major US manufacturer committed to engineering excellence and supplying precision components, guides, rails, and advanced actuators. This is a critical, hands-on engineering role focused on driving innovation within the linear motion industry. If you thrive on tackling complex engineering challenges, owning projects from concept to completion, and pushing the boundaries of mechanical design, we want to hear from you. What You Will Master: Analysis, Design, and Validation As a Senior Mechanical Engineer reporting to Product Design Engineering Manager, you will play a vital role in designing the next generation of components and motion systems, including linear bearings, actuators, and custom motion systems. Design and Development Challenges: • Lead clean-sheet mechanical designs for linear bearings, actuators, and motion systems. • Own the full-cycle development process, ensuring designs move efficiently from concept through validation and ultimate release. • Identify design differentiators by reverse engineering competitive products. Calculations, Testing, and Modeling: You must be comfortable with intensive engineering analysis and dedicated validation to ensure product integrity: • Perform essential engineering calculations, including load analysis, stress analysis, drive load analysis, motion profile analysis, tolerance stack up analysis, and material selection. • Develop comprehensive test plans and execute validation testing to prove models and iterate designs accordingly. • Utilize CAD (SOLIDWORKS) and FEA tools for modeling and simulation. • Create and maintain accurate 3D models, 2D drawings, and Bills of Materials (BOMs). Collaboration and Support: • Ensure designs align with customer needs and manufacturability by working closely with sourcing, manufacturing, and marketing teams. • Support product launches by providing necessary CAD assets, technical data, and content for catalogs. Do You Have What It Takes? We are seeking a candidate who brings a combination of solid mechanical fundamentals and specific linear motion expertise.

Requirements
