Description supplied by the original job listing.
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, it’s required to possess experience and working knowledge at least on electrical principles, structural, architectural, DC operations & maintenance requirements, installation and commissioning procedures.
Client Engagement & Technical Leadership
Act as the primary cooling and mechanical technical contact for clients – leading design reviews, strategy presentations, and bid discussions with senior engineering teams
Directly engage with client-side SMEs, global stakeholders, and multidisciplinary teams
Lead technical discussions on design intent, risks, and trade-offs
Own preparation of design strategy documents and technical narratives
Basis of Design (BOD)
Design Basis Reports (DBR)
Technical narratives and presentations
Participation in proposals drafting and responses to RFP and TQR
Design Leadership & Engineering Ownership
Data Center Cooling Strategy & System Design
Own the complete mechanical design – chilled water plant, direct liquid cooling (DLC), CDU systems, hybrid architectures, heat rejection, ventilation, and fuel systems
Design systems for hyperscale and colocation facilities in the 10–100 MW IT load range (from concept through to IFC)
Handle high-density AI cooling: 40–142 kW per rack, CDU sizing, secondary fluid networks, glycol specification
Ensure compliance with UAE-specific requirements: ZLD heat rejection, PUE <1.4 under Dubai Universal Blueprint for AI, high-temperature DLC for desert free cooling
Lead design of Air-cooled & water-cooled chilled water systems (CRAH / CRAC / AHU)
Define airflow strategies (Hot aisle / cold aisle containment)
Establish resilience strategies (N, N+1, N+2, 2N) aligned with Uptime Tier
Engineering Calculations & Technical Validation
Perform and direct thermal load calculations, hydraulic modelling, and CFD studies for density validation and retrofit assessment
Validate control philosophy and BMS/EMS integration requirements
Review all mechanical engineering calculations and ensure alignment with ASHRAE, TIA-942, and Uptime Institute guidelines
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)
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
Develop the internal design guidelines and lead the DC Mechanical team
Mentor mechanical and HVAC engineers
Establishing design standards and best practices
Contribute to the DC Academy and regional thought leadership programme
Drive design quality, risk management, and technical issue resolution across the team
Mandatory Skills & Experience
Technical Expertise
8+ years of mechanical engineering experience, with at least 5 years focused on data centre or mission-critical cooling systems
Strong track record in chilled water plant design: chillers, pumping configurations, cooling towers, dry coolers, and hydraulic modelling
Hands-on experience designing direct liquid cooling systems: CDU specification, secondary fluid networks, glycol systems (PG-25)
Deep understanding of high-density AI cooling: 40 kW/rack and above, AI cluster thermal management, liquid/air hybrid architecture
Knowledge of UAE regulatory landscape: DEWA ZLD compliance, Dubai Universal Blueprint for AI (PUE <1.2), district cooling integration
Tools & Digital Capability
CFD experience: ability to direct or personally run studies for density validation and retrofit assessment
BIM delivery using Revit at LOD350 and coordinated multi-discipline modelling
AutoCAD proficiency for detailed mechanical drawings and coordination
Communication & Leadership (NON-NEGOTIABLE)
Exceptional verbal and written communication in English – confidence to lead technical discussions at senior level
Ability to mentor engineers and establish design culture and standards
Qualifications & Experience
BE / BTech / ME / MTech in Mechanical Engineering
Professional registration as a Mechanical Engineer or equivalent
Good to Have
Uptime Institute ATD or ATS certification
Experience with immersion cooling systems (single-phase or two-phase) and their commissioning
Familiarity with high-temperature DLC (30–40°C coolant supply) and free cooling integration in hot climates
LEED AP M+E or equivalent sustainability qualification
Experience with KSA regulatory landscape and Vision 2030 data centre programme
