Mechanical Engineer (HVAC Plant Design)

About the Role

The role is part of a team shaping the future of HVAC and energy systems across Ontario and beyond. Engineers early in their careers will own defined scopes while deepening technical judgment in a collaborative environment. Projects focus on institutional, commercial, and infrastructure facilities, helping clients reduce energy use, improve comfort, and modernize essential systems. Key responsibilities include conducting site surveys, preparing mechanical design briefs, performing load calculations, ventilation sizing, and equipment selection. You will develop engineering calculations, technical reports, and construction documentation that meet WSP standards and relevant codes, and produce mechanical drawings and specifications. Collaboration with senior engineers, project managers, and multidisciplinary teams is essential, as is reviewing shop drawings, responding to RFIs, and supporting construction administration. The position also involves contributing to central plant and district energy system designs, participating in client meetings and design discussions, and assisting with proposal efforts such as fee letters and RFP responses.
