What we look for

• Degree in Mechanical Engineering or equivalent.
• 2–5 years’ experience in mechanical building services or industrial MEP design.
• Understanding of chilled water systems, pumping, and basic hydraulic design.
• Ability to produce clear mechanical drawings, technical documentation, and structured Bills of Materials.

Desirable Experience

• Exposure to data centres or other mission-critical facilities.
• Experience using Revit MEP, AutoCAD, and Excel-based BoMs
• Opportunity to travel globally to manufacturing facilities or project sites may be required.
