The Opportunity

Design What Comes Next

Lead the mechanical design of resilient, scalable, mission-critical facilities that enable cloud, artificial intelligence, and high-performance computing across Canada. As a technical leader and Engineer of Record, you will guide multidisciplinary teams and clients through complex data center projects, advancing cooling performance, operational continuity, energy efficiency, and long-term value.

Your Impact

Lead mechanical design, technical delivery, and quality oversight for enterprise, colocation, and hyperscale data center projects.

Serve as Engineer of Record for assigned projects, reviewing and approving engineering deliverables for technical excellence, compliance, quality, and constructability.

Shape resilient cooling strategies using chilled water plants, heat rejection systems, pumping systems, air-cooled solutions, and liquid-cooled architectures.

Advance AI- and HPC-ready infrastructure through direct-to-chip liquid cooling, immersion cooling, rear-door heat exchangers, and Cooling Distribution Units.

Direct Computational Fluid Dynamics analyses to improve airflow management, thermal performance, cooling capacity, and facility efficiency.

Integrate mechanical systems with electrical, structural, civil, controls, commissioning, and operational requirements to deliver coordinated solutions.

Champion BIM and digital engineering practices that strengthen coordination, constructability, project execution, and lifecycle performance.

Grow client trust and team capability through technical advice, mentoring, proposals, presentations, strategic pursuits, and continuous improvement of engineering standards.

The Skills That Set You Apart

Bachelor's degree in Mechanical Engineering and a Professional Engineer (P.Eng.) designation.

Professional licensure in Ontario, Alberta, and/or British Columbia, with the ability to fulfill Engineer of Record responsibilities.

10+ years of progressive mechanical engineering experience, including significant work in mission-critical and data center environments.

Demonstrated expertise in chilled water systems, cooling plants, pumping systems, heat rejection equipment, and air- and liquid-cooled data center architectures.

Experience integrating Cooling Distribution Units and rack-level liquid cooling for high-density AI and HPC computing environments.

Practical experience applying CFD analysis and BIM-based delivery within multidisciplinary project teams.

Working knowledge of critical electrical infrastructure, including utility services, standby generation, UPS systems, power distribution, and redundancy concepts.

Ability and willingness to travel periodically within Canada for client meetings, site visits, commissioning, project start-up, and business development.
