requirements.Prepare mechanical single-line diagrams, schematics, layouts, plantroom arrangements and control philosophies.Coordinate mechanical designs with electrical, architectural, structural, civil, ICT, security and fire-and-life-safety disciplines.Lead mechanical BIM coordination and review Revit models to the required Level of Development.Review CFD analyses for data halls, plantrooms, generator yards and other critical areas.Prepare technical specifications, equipment data sheets, tender documents and contractor scopes of work.Conduct technical evaluations of vendors, manufacturers, specialist subcontractors and tender submissions.Review contractor shop drawings, material submittals, method statements, RFIs and technical deviations.Participate in design workshops, risk reviews, value-engineering exercises and client meetings.Coordinate with local authorities, licensed engineering offices, utility providers and other Authorities Having Jurisdiction in Saudi Arabia.Ensure compliance with the Saudi Building Code, Civil Defense, environmental, municipality and utility requirements.Support Uptime Institute TCDD certification, including technical responses and closure of review comments.Monitor assigned deliverables, resources and design programmes to ensure timely, high-quality submissions.WHAT SUCCESS LOOKS LIKE: Safe, resilient and maintainable mechanical designs that satisfy Tier III or Tier IV requirements and avoid single points of failure.Accurate, coordinated and compliant design deliverables issued on programme and to the required quality.Mechanical systems optimised to meet project energy-efficiency and PUE targets.Effective multidisciplinary, client, authority, vendor and Uptime Institute coordination with timely closure of comments.YOUR EXPERIENCE: QualificationsBachelor's degree in Mechanical Engineering from a recognised university.Eligibility for registration with the Saudi Council of Engineers.Relevant data centre certification, such as Uptime Institute ATD, CDCP, CDCS or equivalent, is preferred.LEED accreditation or a recognised sustainability certification is an advantage.Required ExperienceMinimum 10 years
