Data Center Senior Mechanical Commissioning Engineer

Due to continued project awards, FPC Global is seeking a Senior Mechanical Commissioning Engineer with demonstrable experience delivering Tier III / Tier IV-aligned data centre cooling and mechanical infrastructure.

This role is accountable for the planning, execution, and technical leadership of mechanical commissioning activities across complex mission-critical facilities, ensuring systems meet design intent, availability objectives, redundancy requirements, and operational readiness criteria, in accordance with Uptime Institute, ASHRAE, and applicable international standards.

The position is highly site-focused and requires hands-on leadership through Integrated Systems Testing (IST), including failure mode, redundancy, and fault tolerance validation.

Key Responsibilities

Mechanical Commissioning Leadership

• Lead end-to-end commissioning of mission-critical mechanical systems including:

  • Chilled water and condenser water systems

  • Air-cooled and water-cooled chillers

  • Cooling towers and heat rejection systems

  • CRAH / CRAC units and in-row cooling

  • AHUs, FCUs and pressurisation systems

  • Pumps, valves, controls and associated plant

Integrated Systems Testing (IST)

• Develop and execute mechanical IST strategies and scripts aligned with Uptime Institute methodology.

• Lead failure mode testing, redundancy validation (N, N+1, 2N) and fault tolerance demonstrations.

• Coordinate mechanical participation in black-building and site-wide integrated test scenarios.

FAT / SAT / Functional Performance Testing

• Plan, manage, and witness Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) for major mechanical plant.

• Lead Functional Performance Testing (FPT) under normal, degraded and failure conditions to validate performance and control sequences.

Design & Commissionability Reviews

• Perform design reviews at all project stages from a commissionability, maintainability and availability perspective.

• Review mechanical specifications, P&IDs, control philosophies and vendor technical submittals.

Controls, BMS & EPMS Integration

• Validate integration of mechanical systems with BMS and EPMS platforms.

• Verify alarms, trending, interlocks, sequences of operation and automated response during IST.

Project Interface & Coordination

• Interface with project managers, construction teams, MEP contractors, OEMs and client representatives.

• Coordinate closely with electrical and IT commissioning teams to ensure full MEP and controls integration.

Documentation & Handover

• Develop and manage all mechanical commissioning documentation including:

  • Commissioning plans and execution strategies

  • Test scripts, procedures and checklists

  • Issue logs, punch lists and risk registers

  • Final commissioning reports and systems manuals

• Support client handover and transition to steady-state operations.

Compliance & Standards

• Ensure compliance with relevant standards including:

  • Uptime Institute Tier Standards

  • ASHRAE (TC 9.9, 90.1)

  • Local mechanical and environmental codes

• Support LEED or equivalent sustainability objectives where applicable.

Troubleshooting & Risk Management

• Identify, analyse, and resolve mechanical system deficiencies during commissioning.

• Mitigate risk to uptime, programme, safety and operational performance.

Health, Safety & Leadership

• Enforce strict HSE compliance on site including RAMS reviews, toolbox talks and risk assessments.

• Lead, mentor and coordinate commissioning engineers, subcontractors and vendors.Qualifications

Qualifications & Experience

Essential Qualifications

• Degree in Mechanical Engineering (B.Tech / B.E. or equivalent).

• 10+ years experience in mechanical testing and commissioning.

• Minimum 5 years commissioning data centres or mission-critical facilities, including demonstrable leadership of mechanical IST activities.

Technical Experience

• Deep expertise in:

  • Data centre cooling architectures (air-cooled, water-cooled, hybrid)

  • Redundancy and resilience strategies (N, N+1, 2N)

  • Hydronic balancing, TAB and performance optimisation

  • Failure mode and effects testing (FMET)

• Proven responsibility for technical quality across multiple projects.

Documentation & Technical Output

• Development of commissioning specifications, methodologies and scripts.

• Review and validation of control sequences and operating philosophies.

• Production of detailed technical and executive-level reports.

Tools & Platforms

• BMS / EPMS and digital commissioning platforms.

• AutoCAD / BIM / Visio.

• Exposure to cloud platforms (Google, Microsoft, Amazon) and data analytics.

• Familiarity with RIBA / AIA stages of work or international equivalents.

• Experience with FDD and automated commissioning systems is advantageous.
