Senior Mechanical Engineer Technical Office

About the Role

Dar Al Riyadh Consultants is seeking a Senior Mechanical Engineer for their Technical Office in Riyadh. This full-time role involves leading the technical review and coordination of various mechanical engineering packages for major projects.

Key Responsibilities

• Lead the technical-office review and coordination of irrigation, pumping, HVAC, plumbing, drainage, fire-protection, and other mechanical engineering packages.
• Verify golf-irrigation hydraulic models, including demand distribution, pressure zoning, pipe sizing, friction losses, pump duty points, and critical-node pressures.
• Review transient and surge analyses and validate proposed water-hammer protection, air-release, pressure-relief, and surge-suppression systems.
• Review and recommend approval of mechanical shop drawings for central pump stations, intake structures, filtration skids, chemical-treatment systems, and lake circulation and aeration systems.
• Review clubhouse HVAC calculations and designs, including cooling loads, equipment selection, ventilation, ductwork, chilled-water systems, controls, and energy-performance requirements.
• Review plumbing, water-supply, drainage, stormwater, and fire-protection drawings, calculations, and equipment schedules.
• Evaluate mechanical material and equipment submittals, including high-capacity pumps, VFDs, HDPE piping, motorized valves, chillers, air-handling units, filtration systems, and fire pumps.
• Verify equipment performance curves, system operating points, efficiency, redundancy, maintainability, acoustic performance, and compliance with approved specifications.
• Review Combined Services Drawings, BIM models, and coordinated shop drawings, and resolve interfaces with civil, structural, electrical, irrigation, and landscape networks.
• Provide technically justified responses to complex contractor RFIs, design deviations, value-engineering proposals, and site-related engineering issues.
• Review control philosophies and interfaces among pumps, VFDs, motorized valves, sensors, irrigation controls, BMS, electrical panels, and standby-power systems.
• Review Testing, Adjusting and Balancing plans, inspection and test plans, pre-commissioning procedures, and integrated mechanical commissioning methodologies.
• Assess field changes and ensure that approved modifications are incorporated into calculations, redline drawings, as-built records, and O&M documentation.
• Prepare technical reports and advise the Project Manager on mechanical design risks, noncompliance, outstanding decisions, and matters affecting quality, cost, schedule, safety, or system performance.

Qualifications and Experience

• Bachelor’s degree in Mechanical Engineering from an accredited and recognized university.
• Minimum of 20 years of professional experience in mechanical engineering, technical-office management, and design review.
• Demonstrated experience on major infrastructure, pumping-station, building, or multidisciplinary development projects.
• Proven experience working for an engineering supervision consultancy, project-management consultancy, or design consultant.
• Deep technical expertise in large-scale pressurized hydraulic networks, pumping systems, and automated irrigation infrastructure.
• Strong experience reviewing central cooling plants, HVAC, plumbing, drainage, and fire-protection systems.
• Demonstrated ability to verify hydraulic models, pump selections, surge analyses, and equipment-performance calculations.
• Experience reviewing technical submissions, shop drawings, material submittals, RFIs, and contractor design alternatives.
• Advanced proficiency in WaterCAD, EPANET, AutoCAD, and Revit MEP.
• Ability to review BIM models and resolve complex multidisciplinary interfaces.
• Strong understanding of mechanical testing, TAB, commissioning, and final handover requirements.
• Fluency in written and spoken English is mandatory.
