As a Quality Intern at MacLean-Fogg, you will connect what you are learning in the classroom with the products and processes behind a manufacturing business. You will work with quality professionals, engineers, and production teams to understand requirements, investigate problems, and help make products and processes more consistent.
You will take ownership of a meaningful project with guidance from an experienced team. Depending on your assignment, you might analyze defect trends, investigate a recurring issue, improve an inspection method, or make quality information easier to use. At the end of the program, you will present your work, findings, and recommendations to facility leadership.
