Role Purpose

This site-based role plays a key part in supporting the safe, reliable, and successful transition of a mission-critical data center facility from construction completion through commissioning, integrated testing, operational readiness, and handover. The role requires strong knowledge of mission-critical infrastructure, commissioning execution, system integration, testing documentation, and performance validation across electrical, mechanical, ICT, and compute-related systems.

Key Responsibilities

Commissioning & IST Execution

• Support commissioning and IST execution activities across mission-critical data center systems, ensuring testing is completed safely, accurately, and in accordance with approved procedures.
• Support Integrated Systems Testing for electrical, mechanical, controls, ICT, and computer-related systems.
• Verify that commissioning activities are aligned with approved drawings, specifications, sequence of operations, operational requirements, and client standards.
• Support testing of critical infrastructure, including MV/LV electrical distribution, UPS systems, generators, ATS, switchgear, grounding, cooling systems, CRAH/CRAC units, chilled water systems, BMS, EPMS, fire alarm, ICT, and network infrastructure.

Planning & Documentation Review

• Review and support commissioning plans, method statements, test scripts, IST procedures, checklists, risk assessments, and commissioning schedules.
• Ability to review and interpret commissioning plans, test scripts, drawings, specifications, sequence of operations, method statements, inspection records, and technical documentation.
• Support commissioning documentation, including test records, issue logs, commissioning reports, turnover documentation, and final acceptance records.

System Readiness & Validation

• Assist in validating system readiness before commissioning, including documentation review, installation verification, pre-functional checks, and issue closeout.
• Support GPU and accelerator burn-in testing, including coordination of test environments, equipment readiness, monitoring requirements, and performance validation.
• Support thermal-soak testing activities to validate cooling performance, stability, load response, and environmental control under sustained operating conditions.
• Support compute-fabric validation activities, including coordination with ICT, network, hardware, and operations teams to verify connectivity, redundancy, performance, and system integration.

Coordination & Stakeholder Management

• Coordinate with commissioning managers, contractors, vendors, OEMs, MEP teams, ICT teams, operations teams, and client representatives during testing and validation activities.
• Coordinate with project teams to track and close commissioning issues, punch list items, defects, and non-conformances.
• Coordinate with operations teams to ensure testing outcomes support handover, system reliability, maintainability, and operational readiness.
• Participate in commissioning meetings, readiness reviews, test coordination sessions, daily briefings, and lessons learned reviews.

Monitoring & Reporting

• Monitor and document test results, deficiencies, failures, observations, and corrective actions during commissioning and IST activities.
• Track test results, deficiencies, commissioning issues, punch lists, corrective actions, and closeout documentation.
• Identify commissioning risks, interface issues, access constraints, sequencing gaps, and operational readiness concerns, escalating them to project leadership when required.

Safety & Compliance

• Support safe testing practices, including LOTO, Permit-to-Work, energized systems coordination, test boundary control, and emergency response requirements.
• Ensure understanding of commissioning safety requirements, including LOTO, Permit-to-Work, energized testing, PPE, isolation procedures, and test boundary control.
• Perform other related duties as required and assigned.

Qualifications & Experience

Required

• 10+ years of experience in commissioning, IST execution, data center operations, MEP systems testing, ICT validation, facility engineering, or mission-critical infrastructure delivery.
• Bachelor's degree in Electrical Engineering, Mechanical Engineering, Electronics Engineering, Computer Engineering, Telecommunications Engineering, or a related technical field.
• Experience supporting commissioning activities on data center, mission-critical, high-performance computing, industrial, or technically complex projects.
