Steel Dynamics’ metallurgy internships stand apart from others in the market because they provide a true balance of office-based engineering work and hands‑on industrial experience. Interns are not confined to observing from a distance; instead, they actively work alongside operators and maintenance teams on the production floor, applying engineering principles directly to equipment, systems, and processes. This immersive approach gives interns the opportunity to design solutions, test them in real‑world conditions, and see the immediate impact of their work.

At SDI, metallurgy is not limited to research and development, it is a dynamic combination of technical analysis and practical application that exposes interns to the full scope of how metallurgy drives production success.
