At Ecosystem we believe we should be accountable for results. Thatâs why we've integrated engineering and construction, seeing our projects through from design concept to implementation and commissioning. And that's how we can efficiently solve complex energy and decarbonization challenges in the built environment. Here are some of the projects we've been working on recently: Adelphi University, Brown University and San Diego Padres Stadium. You are a Mechanical Engineering student going into your Senior year, looking for experience and exposure in building mechanics, energy systems and performance. Located at Ecosystemâs Washington office, working on the Georgetown University project you as an intern will join a multidisciplinary and innovative team of technical engineers responsible for the success of multimillion-dollar projects.
