We are seeking an experienced and technically strong Commissioning Engineer to support commissioning, Integrated Systems Testing (IST), and operational readiness activities for a large-scale data center project in KSA. This site-based 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.
The ideal candidate will have experience supporting commissioning and IST execution for data center, mission-critical, high-performance computing, industrial, or technically complex facilities. The role requires hands-on experience with commissioning coordination, test execution, issue tracking, GPU/accelerator burn-in, thermal-soak testing, and compute-fabric validation.
You will play a key role in supporting the safe, reliable, and successful transition of the facility from construction completion through commissioning, integrated testing, operational readiness, and handover.
RESPONSIBILITIES
- Support commissioning and IST execution activities across mission-critical data center systems, ensuring testing is completed safely, accurately, and in accordance with approved procedures.
- Coordinate with commissioning managers, contractors, vendors, OEMs, MEP teams, ICT teams, operations teams, and client representatives during testing and validation activities.
- Review and support commissioning plans, method statements, test scripts, IST procedures, checklists, risk assessments, and commissioning schedules.
- Support Integrated Systems Testing for electrical, mechanical, controls, ICT, and computer-related systems.
- 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.
- Monitor and document test results, deficiencies, failures, observations, and corrective actions during commissioning and IST activities.
- Coordinate with project teams to track and close commissioning issues, punch list items, defects, and non-conformances.
- 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.
- Participate in commissioning meetings, readiness reviews, test coordination sessions, daily briefings, and lessons learned reviews.
- Support commissioning documentation, including test records, issue logs, commissioning reports, turnover documentation, and final acceptance records.
- Identify commissioning risks, interface issues, access constraints, sequencing gaps, and operational readiness concerns, escalating them to project leadership when required.
- Support safe testing practices, including LOTO, Permit-to-Work, energized systems coordination, test boundary control, and emergency response requirements.
- Coordinate with operations teams to ensure testing outcomes support handover, system reliability, maintainability, and operational readiness.
- Perform other related duties as required and assigned.
