Design mechanical systems for data centers and mission-critical facilities, including HVAC, heat-rejection, chilled-water, hydronic, and critical cooling systems.
Perform cooling-load calculations, equipment sizing, capacity planning, and other mechanical engineering analyses.
Prepare mechanical plans, schematics, schedules, details, specifications, and supporting calculations.
Apply applicable Canadian building, mechanical, energy, fire, and plumbing codes and requirements.
Coordinate mechanical designs with architectural, electrical, structural, civil, controls, fire protection, technology, and other disciplines.
Support design criteria addressing reliability, redundancy, resiliency, maintainability, energy efficiency, and capacity.
Participate in multidisciplinary design reviews, quality reviews, and project coordination meetings.
Support construction-phase services, including RFIs, submittal reviews, site observations, commissioning activities, and resolution of technical issues.
Coordinate with clients, contractors, vendors, utilities, and other project stakeholders.

Working knowledge of applicable Canadian building, mechanical, energy, fire, and plumbing codes and requirements.
Registered, or eligible to register, as a Professional Engineer within Canada.
Strong communication, collaboration, and problem-solving skills.

Preferred Qualifications

Experience with hyperscale, colocation, mission-critical, healthcare, laboratory, industrial, or other complex facilities.
Experience designing data center HVAC, cooling, and heat-rejection systems.
Knowledge of reliability, redundancy, resiliency, and maintainability concepts.
Experience with chilled-water systems, cooling towers, dry coolers, CRAH/CRAC units, fan-wall systems, economizers, hydronic distribution, or liquid-cooling technologies.
Experience with computational fluid dynamics, energy modelling, or other mechanical-system analysis tools.
Experience with Revit and Autodesk Construction Cloud.
Familiarity with applicable ASHRAE, CSA, NFPA, Uptime Institute, TIA-942, ANSI/BICSI 002, and other data center industry standards.
