Brown & Beattie Ltd. is looking for a Mechanical Engineer with 7-10 years of experience in building systems who is ready to take on a high responsibility ownership, client-facing role focused on existing buildings, retrofits, and capital planning projects. If you do not currently hold a P.Eng. designation in Ontario, or are not located within commuting distance of the GTA, this role will not be the right fit.

What You’ll Be Doing

As a Mechanical Engineer, you will be responsible for assessment of existing building mechanical systems as well as design of replacement systems such as boilers, chillers, cooling towers, make-up air units and others. A working knowledge of building electrical systems as they pertain to mechanical systems and building mechanical equipment upgrades is a must.

Duties will include drafting specifications, construction review, progress reports, and client liaison. In this role you’ll manage a portfolio of projects with strong support and clear ownership. You will also be working directly with clients, contractors, and internal team members, so strong communication and organization skills are important.

There is a clear path to increased responsibility over time, including the opportunity to take on a leadership role within the mechanical discipline. The work is varied and practical, with a mix of office-based tasks, site visits, and client interaction.

Who This Role Is For

This role is best suited for a Mechanical Engineer with experience in building systems, particularly in retrofit, restoration, or consulting environments.
