Principal Engineer Mechanical Data Center Dubai

Key Responsibilities

The Principal Mechanical Engineer will act as a technical lead and subject matter expert for mission-critical Data Center projects responsible for end-to-end HVAC design engineering coordination and commissioning support.

This role goes beyond design and requires complete lifecycle ownership from concept definition and cooling strategy to detailed design construction support commissioning and performance validation.

You will be responsible for advising on AI deployment options and examining potential impact on the design by leading cross-discipline conversations. Therefore its required to possess experience and working knowledge at least on electrical principles structural architectural DC operations & maintenance requirements installation and commissioning procedures.

  1. Detailed Design & BIM Coordination
• Lead development of concept schematic and detailed design (IFC level) documentation
• Review and approve AutoCAD & BIM (Revit) models at LOD350 with coordinated multi-discipline integration
• Spot and resolve cross-discipline conflicts at concept stage (electrical ELV fire structural)
  1. Project Delivery & Construction Support
• Lead multidisciplinary coordination across Electrical Structural Architectural Fire Protection and BIM teams
• Support procurement: technical specifications BOQs and vendor evaluations
• Provide technical support during construction site inspections and commissioning phases

Team Leadership & Capability Building
