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

Who we are

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.

Why This Role Matters

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.

What You Will Do

Technical Management & System Design

• Conduct on-site assessments of BAS and mechanical systems.
• Analyze BAS legacy sequences and architectures for optimization opportunities.
• Specify BAS components and design custom control strategies.
• Ensure mechanical system designs are fully controllable and aligned with automation strategies.
• Review mechanical and control system designs, drawings, and sequences of operation to understand system intent and identify controls requirements.
• Contribute to the development or refinement of HVAC control design, sequences and points lists based on project requirements.

Project Development & Bidding

• Assist with controls assessments during bid phases and generate scope estimates.
• Prepare RFP documentation, including sequences and points lists.
• Support client presentations and internal reviews pre-award.

Construction & Commissioning

• Oversee BAS installations; liaise with contractors and project teams.
• Attend start-ups to ensure readiness and validate programming.
• Confirm implementation of control logic and user-friendly interfaces.
