Senior Design Engineer - Multiple Teams

Salary Range: 100 to 150 (Currency: USD) (Pay period: per-year-salary)

What you will do

At Ecosystem, you won’t be working on standard projects with off-the-shelf solutions. You will be involved in existing buildings that are energy-intensive and complex, designed in a time when energy was inexpensive. Each project is unique and requires critical thinking, creativity, and resourcefulness.

You will take part in the development of energy performance projects, from audit to construction and through to results validation. Here, you won’t be given a step-by-step manual- instead, you’ll be told what the building needs to achieve, and you’ll have the freedom, resources, and tools to determine how to get there.

Specifically, you will:

Act as the single point of ownership for assigned projects, leading both project and design management

Serve as lead engineer, managing project timelines, workstreams, budgets, and mentor junior team members while ensuring effective collaboration with MEP firms and client stakeholders

Review and enhance MEP drawings and designs to optimize system performance and reduce project cost

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/ 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 a combination of 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
