Lead Mechanical Engineer- Mission Critical Data Centers

Job Description

About The Role

Key Responsibilities

• Lead the mechanical design for mission critical facilities, covering HVAC, chilled water systems, air distribution, heat rejection systems, and integration with electrical and ICT systems.
• Develop high-quality designs, specifications, and technical reports in line with client requirements, local regulations, and international standards.
• Deliver thermal load assessments, capacity planning, redundancy and resilience strategies (e.g., N+1, 2N) for critical cooling systems.
• Integrate energy efficiency, free cooling, and sustainable technologies into design strategies to minimize operational costs and environmental impact.
• Coordinate closely with electrical, structural, public health, fire protection, and ICT teams to ensure fully integrated, clash-free, and optimized designs.
• Lead technical reviews, ensure quality control of design deliverables, and manage budgets, deliverables, and programme schedules.
