    JOB DESCRIPTION: CMTA, a Legence company CMTA is one of the fastest growing engineering firms in the U.S., with nationally recognized expertise in sustainable, high-performance building engineering.

We focus on finding engineers whose skills and personalities drive them to excel, fostering a workplace that provides unparalleled growth and career opportunities. The core business of our Energy Solutions division is the delivery of Guaranteed Energy Savings Performance Contracts (ESPCs). Simply put, our ESPCs are a viable way to upgrade and renovate facilities in a budget-neutral or even budget-positive way.

Each stage offers a variety of valuable experiences, from initial development through implementation.
