Building Automation Specialist

Do you know how to turn a refrigerator into an air conditioner for an apartment?

If you can answer this question, and you are ready to apply your problem-solving skills on real-world projects, come join our team!

At Ecosystem, we believe we should be accountable for results. That’s 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:
Georgetown University, Adelphi University, San Diego Padres Stadium, Ventas - Battery Park City.

As a Building Automation Specialist in DC, Your expertise will ensure the success of multimillion-dollar energy projects. You will bridge complex MEP design with real-world building performance—engineering custom control strategies and optimizing mechanical systems to meet energy, comfort, and operational goals. From pre-design through commissioning and beyond, your input will deliver measurable ROI and long-term sustainability.
