Steel Dynamics • Sinton, TX

8h • Onsite

About The Position

Steel Dynamics is a leading industrial metals solutions company that produces lower-carbon, high-quality steel products primarily from recycled scrap. Operating through a circular manufacturing model, the company manufactures a wide range of steel products including flat roll, structural, and long products for industries such as construction, automotive, energy, and manufacturing. In addition to steel production, Steel Dynamics operates metals recycling facilities, steel fabrication plants, and aluminum production operations, serving customers across North America with a focus on innovation, efficiency, and sustainability.
This internship is unique compared to other software development internships because instead of creating software to be sold to external companies, interns at SDI develop and debug applications that directly serve our internal customers. This means interns work closely with employees across the company, particularly those in operations, to understand their day-to-day needs and challenges. By building software that improves internal processes and supports SDI’s workforce, interns gain firsthand experience in creating practical solutions while developing strong relationships with internal customers. This direct interaction not only strengthens communication and problem-solving skills but also provides valuable insight into how technology supports a large-scale manufacturing environment.
This internship is located at the Steel Dynamics Sinton Flat Roll Division located in Sinton, TX, in the Casting Department. This internship will take place during Summer 2026.
