Solar Engineer Intern/Co-op Fall 2026 - Energy Solutions

CMTA • Fairfax, VA

5d • Onsite

About The Position

The core business of our Energy Solutions division is the delivery of Guaranteed Energy Savings Performance Contracts (ESPCs). ESPCs are a way to upgrade and renovate facilities in a budget-neutral or even budget-positive way by diverting money already being spent on utilities into facility upgrades. This includes scope development, design, bidding, construction management, commissioning, measurement and verification, and ongoing energy management services. CMTA Energy Solutions has a robust co-op program for college students pursuing a degree in Mechanical Engineering, offering an immersive experience in Guaranteed Energy Savings Performance Contracting for two or more semesters. Co-ops build industry-competitive skills in a hands-on environment through collaborative project tasks with full-time engineers under the direct supervision of Professional Engineers. The program is designed to develop students into full-time caliber employees. The ideal candidate will possess excellent interpersonal skills and be able to work well both as a team member and independently. Our program stands apart from typical co-op rotations by allowing co-ops to stand out and take on challenging projects. Co-ops will be involved with multiple Guaranteed Energy Savings Performance Contracts and will have a role in every stage of their development, from initial development through implementation. Whether co-ops are interested in building their skill set in identifying and calculating energy savings measures, developing renovation documents, or hands-on field experience, CMTA Energy Solutions aims to exceed expectations. Solar Co-ops can expect hands-on experience with photovoltaic systems, and by the end of the program, co-ops will have gained the experience to deliver a full photovoltaic design from scratch. Our Solar co-op will directly support our solar project managers.
