About the role

FSB, an affiliate of Colliers Engineering & Design, is offering a hands-on Summer Internship for Mechanical Engineering students ready to take engineering concepts out of the classroom and into real buildings. As an intern, you’ll work alongside licensed mechanical engineers and experienced designers while gaining experience with the HVAC, plumbing, and piping systems that make buildings comfortable, functional, efficient, and safe.

You’ll contribute to projects ranging from hangars and higher education facilities to mission critical environments, healthcare facilities, commercial buildings, tribal facilities, and more.

This is more than a summer of shadowing. You’ll contribute to active projects, strengthen your technical skills, make professional connections, and experience what working as a mechanical engineer within a multidisciplinary A/E firm is really like.
