Job Summary

Mazzetti is seeking Mechanical, Electrical, and Plumbing (MEP) Engineering Interns to join our team for Summer 2027. This internship is designed for students pursuing a degree in Mechanical, Electrical, Architectural, or a related engineering discipline who are interested in gaining hands-on experience designing building systems. 

The Mazzetti Summer Engineering Internship Program is an 8–12 week experience designed to bridge classroom learning with professional engineering practice. As an intern, you’ll contribute to active project work while learning how MEP systems are designed, modeled, coordinated, and ultimately brought to life.

Depending on your discipline and project assignments, your experience may include building calculations, system modeling, construction drawings, interdisciplinary coordination, sustainability initiatives, and limited construction observation. Throughout the summer, you’ll also participate in structured onboarding, mentorship, learning and development opportunities, ongoing feedback, and activities designed to connect you with people and areas of expertise across Mazzetti.

Join us in shaping a brighter future through engineering and innovation.
