Original job description

What if you could redefine what’s possible?

With us, you can. You want Purpose. Growth. Opportunity. People who get it.

We are the home of ambitious, passionate, and innovative world shapers.

With an unmatched breadth and depth of engineering, advisory and science-based expertise, our global minds unite to power local solutions.

We are pathfinders and impact makers.

We are Visioneers.

We are WSP.

The Opportunity

Design What Comes Next

Bring your mechanical engineering expertise to WSP’s Buildings M&E team and help shape spaces where people work, shop, receive care, and connect. You’ll contribute to diverse Canadian projects spanning commercial buildings, retail environments, warehouses, tenant fit-outs, niche healthcare clinics, and specialty spaces. Many assignments involve multi-location programs, offering exposure to national standards and coordination challenges that go beyond single-site work.

Working alongside architects, landlords, contractors, and multidisciplinary colleagues, you’ll turn technical requirements into practical, coordinated solutions while helping projects move effectively from design through construction.

Your Impact

Design mechanical building systems, preparing drawings and specifications for HVAC, plumbing, drainage, and fire protection using Revit and AutoCAD.
Develop heating and cooling load calculations, equipment selections, and coordinated ductwork, piping, and sprinkler head layouts.
Apply OBC, ASHRAE, NFPA, client standards, and other applicable requirements to deliver technically sound designs.
Support projects through construction by responding to RFIs, reviewing shop drawings, and conducting site visits.
Coordinate with electrical designers and other disciplines to create integrated building solutions.
Strengthen design quality by participating in internal QA/QC processes and technical reviews, including reviewing and sealing peer-prepared materials where appropriate.
Collaborate directly with clients, project stakeholders, architects, landlords, and contractors while managing multiple assignments in a fast-track environment.

The Skills That Set You Apart

Bachelor’s degree in Mechanical Engineering and licensure as a Professional Engineer (P. Eng.).
10+ years of experience in mechanical building systems design.
Proficiency in Revit, with the ability to use it effectively on multidisciplinary building projects.
Experience with HVAC calculation tools such as HAP, including heating and cooling load calculations and equipment selection.
Strong working knowledge of OBC, ASHRAE, NFPA, and other applicable mechanical building codes and standards.
Demonstrated ability to communicate technical information clearly in client-facing and multidisciplinary project environments.
Ability to work independently, prioritize competing demands, and deliver across multiple fast-paced assignments.
Experience coordinating project teams and draftspersons is an asset.
