• Coordinate commissioning activities with planners, package managers, vendors and specialist subcontractors
• Manage commissioning trackers, test packs, scripts and sign off documentation
• Witness and verify mechanical commissioning activities including pressure testing, flushing, balancing and functional testing
• Lead walkdowns, tag walks and system completion reviews
• Chair commissioning meetings and provide structured weekly progress and risk reports
• Identify programme or quality risks early and work with PM and QS teams to mitigate impact
• Oversee snag management and ensure timely close out of mechanical defects
• Ensure client training, O&M documentation and final handover deliverables are completed to data centre standards
• Maintain strict adherence to health and safety procedures throughout commissioning phases

About You

• Mechanical Engineering degree or trade background with strong commissioning progression
• Proven experience as a Mechanical Commissioning Lead, Commissioning Manager or Senior Commissioning Engineer on data centre or mission critical projects
• Strong knowledge of HVAC systems, chilled water systems, plantrooms and large scale mechanical installations

• Confident leading vendors, subcontractors and junior engineers
• Detail focused with a structured approach to documentation and quality control
• Strong communication skills and ability to represent the project in front of the client
