Mechanical Engineer Internship Summer 2027 - Boston, MA
About the role
PAE is an engineering and design firm that turns complex challenges into reality. By leveraging the latest technologies, we solve problems in unique ways, and our designs enable buildings and communities to be more resilient and efficient. PAE is trusted by our clients in every aspect of a project's lifespan, from idea to occupancy. We set ambitious goals backed by analysis to significantly conserve water and energy while balancing costs and long-term operational needs. As a B Corp, we measure success by the benefits our projects provide to our clients, our communities, and our planet. We embrace innovation, transparency, sustainability, and lifelong curiosity.
The internship program provides hands‑on experience in sustainable engineering design. The 10 to 12 week paid program gives interns the opportunity to learn about the building design industry from a traditional viewpoint, and to learn the PAE and LUMA way. Internships are available in mechanical, plumbing, electrical, lighting design, regenerative design, and building systems technology design. Interns work directly as part of our engineering and design teams, from small retrofits to high‑profile Living Buildings, gaining an understanding of the entire design process — planning, execution, and problem solving.
Founded in 1967, PAE is a leading sustainable engineering and consulting firm on a mission to deliver clean air, energy, and water for all. We specialize in mechanical, electrical, and plumbing engineering, building performance analysis, technology design, and lighting design (LUMA).

Our portfolio includes over 100 LEED Platinum projects as well as dozens of projects that have either achieved or are pursuing the Living Building Challenge, Passive House, Architecture 2030, Carbon Neutral, Net Zero Energy, and Net Zero Water.
