AECOM is seeking a Senior Mechanical Engineer, to join our growing Canadian Data Center team.

This is a senior, hands-on technical role for an experienced mechanical engineer ready to tackle the scale, speed and complexity of hyperscale, colocation and mission-critical facilities. This is a newly created position

You will design advanced cooling and mechanical infrastructure, solve complex engineering challenges, collaborate with clients and multidisciplinary teams, and help develop the next generation of engineers.

What You'll Do

- Lead mechanical design for hyperscale, colocation and mission-critical data centers.
- Design HVAC, heat-rejection, chilled-water, condenser-water and critical mechanical systems.
- Develop solutions using CRAHs, CRACs, fan-wall systems, economization, in-row cooling and containment technologies.
- Support high-density and liquid-cooling applications, including direct-to-chip technologies.




- Perform heat-load calculations, capacity planning, airflow studies and CFD analysis.
- Design resilient, redundant and fault-tolerant systems for continuous operations.
- Advance energy-productive and sustainable cooling strategies.
- Prepare engineering calculations, equipment selections, specifications and technical documentation.
- Coordinate with electrical, structural, architectural, civil, fire protection and controls disciplines.
- Support construction, RFIs, shop drawing reviews, commissioning, startup and turnover.
- Work directly with clients, contractors, vendors and project stakeholders.
- Mentor junior and intermediate engineers and designers.
- Support proposals, pursuits and technical presentations.
