Mechanical Engineer Intern/Co-op Fall 2026

About CMTA and Energy Solutions

CMTA, a Legence company, is one of the fastest-growing engineering firms in the U.S., recognized for its expertise in sustainable, high-performance building engineering. Our Energy Solutions division specializes in Guaranteed Energy Savings Performance Contracts (ESPCs), a unique approach that upgrades and renovates facilities in a budget-neutral or even budget-positive manner. By diverting existing utility spending into facility upgrades, we cover everything from scope development and design to construction management, commissioning, and ongoing energy management.

We have designed some of the nation's most energy-efficient buildings, including numerous zero-energy structures. Our deep knowledge in the Guaranteed ESPC market allows us to dive deeper than competitors, offering a collaborative, innovative, and data-driven environment for our team.

The Co-op Experience

CMTA Energy Solutions offers a robust co-op program for Mechanical Engineering students that stands apart from typical rotational experiences. Rather than a rehearsed rotation where every student gains the same experience, our program is designed for co-ops to stand out by taking on challenging, real-world projects.

You will work under the direct supervision of Professional Engineers, collaborating with full-time staff on multiple Guaranteed ESPC projects. This immersive experience spans every stage of project development, from initial site visits and building audits to implementation. You will gain hands-on exposure to photovoltaic systems, LED lighting designs, geothermal HVAC systems, and building automation systems. By the end of the program, you will have developed competitive industry skills and the potential to transition into a full-time role with one of the country's fastest-growing Energy Service Companies (ESCOs).

We are looking for candidates who possess excellent interpersonal skills and the ability to work both independently and as part of a team. If you are pursuing an undergraduate degree in engineering from an ABET-accredited university and are ready to contribute to our mission of sustainable building engineering, we invite you to apply.
