Mechanical Commissioning Engineer - Data Centre

Denmark | Permanent | Up to €100,000

A major international engineering contractor is looking for a Mechanical Commissioning Engineer to join a large-scale data centre project in Denmark.

This is a hands-on commissioning role for someone who wants to be on site, close to the systems and involved in taking complex mechanical infrastructure from installation through testing, commissioning and handover.

With 5+ years of secured project work, this is a genuine long-term opportunity rather than a short-term project.

What You'll Be Doing

• Deliver mechanical pre-commissioning and commissioning activities
• Review IFC drawings, specifications and technical submittals
• Support commissioning plans, methodologies and sequencing
• Coordinate with package engineers, planners, vendors and site teams
• Prepare and review checklists, scripts and test packs
• Witness functional testing and verify system performance
• Lead/support walkdowns, tag walks and inspections
• Track commissioning progress, snags and close-out
• Support system handover, O&M documentation and client training
• Identify issues early and escalation commissioning risks

What We're Looking For

• Mechanical commissioning experience within complex construction projects
• Strong knowledge of HVAC, chilled water, LTHW, ventilation and pressurisation systems
• Understanding of commissioning processes, sequencing and system interfaces
• Comfortable working in a fast-paced, site-based environment
• Strong communication skills and the ability to work across multiple disciplines
• A practical, hands-on approach with strong attention to detail

Data centre experience is a major advantage, but strong mechanical commissioning experience from other mission-critical or technically complex environments will be considered.

Why Apply?

• Up to €100,000 salary
• Major data centre project in Denmark
• 5+ years of secured work
• International project environment
• Career development and progression opportunities
• Opportunity to work on technically advanced projects
• Strong overall package
