Lead Mechanical Commissioning Engineer

MCR are seeking to hire an experienced Lead Mechanical Commissioning Engineer to work on large-scale datacenter construction programs in Singapore.

This is a hands-on leadership opportunity for a mechanical commissioning specialist focused on ensuring mission-critical mechanical systems (HVAC, cooling, chilled water, etc) perform reliably from handover through to operational readiness. 

What you will do

• You will serve as the commissioning authority, overseeing full lifecycle mechanical commissioning for data centre projects
• Develop and execute commissioning plans, scripts, and protocols aligned with ASHRAE standards and Owner's Project Requirements
• Lead inspections, functional performance testing, integrated systems testing, and issue resolution for mechanical infrastructure
• Ensure compliance with design intent, energy efficiency goals, and operational reliability
• Produce comprehensive reports, train operations teams, and facilitate smooth handover

What you will need:

• You will have prior datacenter commissioning experience, including hyperscale, colocation, or mission-critical facilities
• Solid working knowledge of ASHRAE commissioning standards and guidelines
• Experience leading mechanical commissioning activities: developing test plans/procedures, witnessing factory and site testing, integrated systems testing (IST), failure mode simulations, and handover documentation
• Strong background in mechanical systems for datacenters (e.g., CRAC/CRAH units, chillers, pumps, piping, BMS integration)
• Relevant qualifications (e.g., Mechanical Engineering degree, commissioning certifications)

If you have a strong track record in datacenter mechanical commissioning, deep ASHRAE expertise, and thrive in an independent, high-stakes environment, we want to hear from you.
