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.     Your Tasks Will Involve Design & Modeling Assist with building calculations that support mechanical, electrical, or plumbing system designs. Learn to model MEP systems using industry-standard engineering and design tools. Support the preparation and refinement of construction drawings as part of a project team.

Develop experience with tools such as Revit while contributing to real project deliverables. Learn Mazzetti’s engineering standards, workflows, and approach to quality. Sustainability & Innovation Gain exposure to sustainable building design and Mazzetti’s approach to creating healthier, more resilient environments. Support sustainability initiatives such as LEED documentation or energy modeling when applicable to assigned projects.

Learn how sustainability and innovation are incorporated into engineering design and decision-making. Collaboration & Coordination Work alongside engineers, designers, project managers, and professionals from other disciplines on active projects. Participate in project planning and design discussions to better understand real-world engineering challenges and decision-making. Coordinate with project team members and other disciplines to understand how building systems come together.

Build relationships with mentors, peers, and professionals across Mazzetti while developing technical and professional skills. Construction & Observation When project o
