Job Description

Who we are

Here are some of the projects we've been working on recently: Adelphi University, Brown University and San Diego Padres Stadium

What you will do

At Ecosystem, you won’t work on standard projects with off-the-shelf solutions. You’ll take on existing, energy-intensive, and complex buildings—designed at a time when energy was inexpensive. Every mandate is unique and calls for technical rigor, curiosity, ownership mindset and comfort with complexity.

Here, you won’t be handed a manual. We define what the building needs to achieve, and you’ll have the freedom, tools, and support to determine how to get there. You’ll lead the implementation phase - from pre-construction through day-to day construction activities, delivery and close out - leveraging both your engineering technical background and your project management skills to deliver guaranteed outcomes in safety, client satisfaction, budget, performance.

More specifically, you will:

Challenge design assumptions and validate that solutions will meet expected energy and performance outcomes.

Oversee on-site construction operations, coordinating subcontractors, clients, and key stakeholders.

Drive project success within a highly integrated team working seamlessly from design through execution, with safety and quality always top of mind.

Act as the technical SME on site, solving complex challenges and identifying efficient, cost-effective solutions.

Navigate change and scope evolution, balancing cost, schedule, technical performance, and team dynamics.

Propose, estimate, and present project upgrades to the client.

Take full ownership of construction execution, ensuring alignment with budget, schedule, and quality standards.

Deliver an exceptional client experience by owning the relationship, anticipating needs, building trust and driving operational outcomes beyond project deliverables.

Your professional growth is an integral part of your role. At Ecosystem, you are encouraged to continuously sharpen your expertise, and step outside conventional boundaries. We value audacity: where others wait for solutions to be proven, we choose to be among the first to innovate.

This role is based full-time on site to support effective execution and collaboration.
