About the role

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: University of Toronto, Toronto Zoo and San Diego Padras Stadium.

Why This Role Matters

As Senior Building Automation Specialist, you'll play a key technical and strategic role as we continue to grow. You’ll bring your expertise to multimillion-dollar energy projects, turning complex MEP designs into high-performing building systems. By developing custom control strategies and optimizing mechanical systems, you’ll help achieve ambitious energy, comfort, and operational goals. From pre-design through commissioning and beyond, your work will deliver measurable ROI and long-term sustainability.

What You’ll Do

Technical Leadership & System Design 
  • Conduct on-site assessments of BAS and mechanical systems. 
  • Analyze BAS legacy sequences and architectures for optimization opportunities.

  • Lead or support full commissioning to ensure systems perform to specifications. 
    •  
    Optimization, Monitoring & Client Support 
  • Optimize programming to meet performance guarantees post-installation. 
  • Train client facilities staff on BAS and integrated system operation and provide clients with clear, actionable technical insights. 
  • Monitor system data during the M&V phase and troubleshoot anomalies. 
  • Support data collection and reporting for ongoing performance validation. 
    •  
    Mentorship & Internal Innovation 
  • Mentor junior engineers and technicians on controls design and commissioning best practices. 
  • Champion cross function knowledge transfer to internal Project Team: engineers/ construction managers/ subcontractors.

    • What You Bring

  • Degree in Mechanical, Electrical, or Instrumentation Controls Engineering, or equivalent experience. 
  • 8+ years of hands-on experience in control systems from leading integrators or manufacturers, such as Delta Controls, Distech Controls, Johnson Controls, Siemens, Honeywell, and Tridium. 
  • High proficiency in BAS platforms and software tools. 
  • Deep understanding of HVAC systems and control logic. 
  • Skilled in field troubleshooting, commissioning, and integration of building systems. 
  • Effective communicator, capable of translating technical concepts for clients and stakeholders. 
  • Comfortable with 60% on-site presence for project execution and client support

    • What Ecosystem Offers

  • Annual base salaries benchmarked and reviewed annually, ranging from 100,000 - $130,000, with final compensation determined based on a candidate’s experience, technical expertise, and skillset.
