MBA Summer Internship: Leadership, Strategy, & Operations - Products & Publishing (MBA Class of 2028)

Who We Are

McMaster-Carr is a leading e-commerce company that industrial customers have trusted for over 120 years. Our products help them get manufacturing lines back up quickly, keep operations running smoothly, and prototype the next generation of innovative solutions. We earn and keep that trust by offering the right products, making them easy to find, and delivering them fast, so our customers can solve problems with greater speed, precision, and ease.

Our industry-leading e-commerce experience, indispensable product selection, and world-class service brings hundreds of thousands of customers to our site each day. But we’re never standing still. Our curious, exceptional people are at the heart of our evolution. They turn new challenges and disruptive technologies into opportunities to refine our operations, expand our offering, and deliver a better experience for every customer.

What You’ll Do
As an intern on the Products and Publishing management team, you’ll lead high-impact work that shapes how we serve customers and grow the business. This MBA internship is your gateway to a full-time role on our Chicago management team, with a clear path to senior leadership. Your growth will be fueled by the impact of your work, not rigid timelines or predetermined milestones. As part of our management team, you'll take on broad, business-critical challenges across the business, including: 

• Own a product line. Take full ownership of a product group and make decisions that directly shape our business and improve customer outcomes. The insights you gather—from customer feedback to industry developments to patterns across our broader offering—will guide what we sell and how we curate it. Your choices will help customers find what they need faster, make better decisions, and get back to work with confidence, while driving growth for McMaster-Carr.
• Strengthen our supplier base and cost discipline. Assess the health of our supplier network and recommend changes to ensure we’re sourcing from high-quality manufacturers with competitive pricing and reliable delivery. Develop cost management strategies that help us optimize how we purchase and manage inventory. Your work will improve product availability, reduce costs and risks, and support better outcomes for both the business and our customers.
• Launch new website features. Collaborate with our tech teams to design, test, and scale features that improve how customers navigate and interact with our site. Whether you're streamlining search, enhancing navigation, or introducing new designs, your work on our digital publishing teams will help customers find the right products faster and with less effort.
• Lead teams that explain industrial concepts for customers. Manage research and creative teams that make complex industrial ideas easy to understand. By delivering clear, useful curation of industrial concepts, you’ll help customers solve problems more effectively and choose the right products with confidence.

Who You Are

You’re energized by shaping direction and rolling up your sleeves to drive results. You thrive in ambiguity, take ownership of meaningful outcomes, and bring others with you—building trust, sharing context, and solving problems through collaboration. You may come from consulting, engineering, banking, or somewhere entirely different. What matters most is how you think, how you learn, and how you lead. If you're curious, driven, and eager to take on challenges that matter, McMaster-Carr offers the chance to make an impact and grow into a leader.
