MEP Engineer - Design & Construction

At Ecosystem we believe we should be accountable for results. We integrate engineering and construction to move projects from design concept to implementation and commissioning, solving complex energy and decarbonization challenges in the built environment. Our recent projects in the US include San Diego Padres Stadium, Con Edison:
Utility Thermal Energy Network, and the Museum of Arts and Design.

In this role, you’ll work hand-in-hand with clients and stakeholders to design unique, and sometimes unconventional, solutions that tackle the most pressing challenges in sustainable construction and energy retrofits across New York. You’ll see your ideas implemented in real buildings, learn from the process, and witness the tangible impact of your work. You’ll monitor project performance after completion, verify energy savings, and ensure our multimillion-dollar solutions deliver real, measurable results for our clients.

This role is for engineers who are motivated by complexity, thrive on autonomy, and want the freedom to make decisions that transform how buildings consume energy.

• Gather and analyze client energy bills to identify potential energy savings based on current energy rates and the building’s energy use intensity (EUI).
• Analyze mechanical, electrical, and control drawings and perform site surveys to understand the operation of the building.
• Develop energy conservation measures based on clients’ needs and financial parameters.
• Develop and perform calculations using software and simulations of potential energy savings from the proposed design.
• Select equipment based on energy performance.
• Prepare project construction budgets and develop financial models.
• Provide technical assistance to the Construction Manager during the construction phase of the project.
• Monitor project performance to ensure attainment of anticipated energy savings.
• Develop technical concepts and associated written documentation required by the Client Acquisition Team and support the Sales Team in identifying clients’ needs.
• Participate in internal and external meetings/presentations and nurture client relationships.

• Bachelor’s degree in Mechanical, Chemical or Physics Engineering.
• 5 to 10 years of relevant experience in Design Engineering or Mechanical Systems Design.
• Proven ability to translate theoretical expertise and past experience into practical solutions, leveraging intuition, technical knowledge, and collaboration with other engineers.
• Excellent communication skills and an aptitude for writing to draft technical reports, present proposals, and engage directly with stakeholders.
• Experience with energy efficiency and decarbonization projects is an advantage.

• End-to-end project ownership: take full accountability of projects from design to delivery and completion, with the autonomy to make decisions and see the results of your designs come to life.
• Career growth & open communication: grow in a culture of transparency and support, with direct access to leadership, and tailored development through training, mentorship, and career planning.
• Generous paid time off: minimum of 15 vacation days, 5 personal days, 10 public holidays, plus a week off to recharge during the end-of-year holidays.
• Employer contribution to 401(k) and a complete Group Insurance package with easy access to health and support through Telemedicine and the Employee Assistance Program.
• Annual base salary, approximately $100,000–$140,000, based on location and experience, with annual reviews to stay market-competitive in the US.
• You decide when visits are valuable — mileage and meals are covered on-site.
• Cell phones provided for professional and personal use.
• Our approach to working together is built on trust, collaboration, and accountability. Flexibility depends on the role, with some teams requiring time on-site or in the office. We come together to connect, learn, and succeed as a team during key moments.
• People-first culture: we live our values through DEI, CSR, Innovation, and Social Committees, and celebrate our shared success at events like Ecofest.
