About the Role

SGS is looking for an experienced Lead Electrical Commissioning Engineer to support a major Tier III / AI Data Center project in Saudi Arabia.

The ideal candidate will have strong hands-on experience in electrical testing and commissioning of large-scale or hyperscale Data Centers, including high-voltage power systems, critical power infrastructure, integrated systems testing, and electrical failure simulations.

Key Responsibilities

• Lead electrical testing and commissioning activities across Data Center commissioning levels, from initial inspections and equipment testing through integrated systems testing and final handover.
• Oversee commissioning of HV/MV/LV electrical systems, substations, transformers, switchgear, UPS systems, generators, ATS and critical power distribution.
• Plan, review and execute commissioning procedures, test scripts, method statements, risk assessments and commissioning documentation.
• Lead or coordinate Integrated Systems Testing (IST), including utility failure simulations, generator failure scenarios, UPS failure testing, load-transfer testing and redundant power-path failure simulations.
• Conduct and coordinate black-building tests and electrical system reliability testing.
• Verify protection relay testing, electrical protection coordination, system redundancy and operational resilience.
• Coordinate with mechanical, BMS, EPMS, fire and life safety, ICT and other commissioning teams to ensure integrated system performance.
• Manage commissioning issues, technical investigations, corrective actions, test records and final handover documentation.
• Ensure compliance with project specifications, applicable electrical standards, safety procedures and Data Center reliability requirements.

• Bachelor's degree in Electrical Engineering from a recognised university.
• Minimum 12 years of relevant professional experience in electrical engineering, testing and commissioning.
• Demonstrated hands-on experience commissioning Tier III / Tier IV or hyperscale Data Centers.
• Strong knowledge of HV/MV/LV electrical infrastructure, substations, transformers, switchgear, UPS, generators and ATS.
• Practical experience in Integrated Systems Testing, electrical failure simulations, load transfers and black-building testing.
• Experience with protection relay testing, electrical protection coordination and critical power-system reliability.
• Ability to lead commissioning activities, coordinate multidisciplinary teams and manage technical issues independently.
• Strong technical documentation, communication and stakeholder-management skills.

Preferred Experience

• Experience on large-scale or hyperscale Data Center projects, including AI Data Center infrastructure.
• Direct involvement in Level 6 Integrated Systems Testing, where applicable to the project commissioning methodology.
• Experience with redundant power architectures such as N+1 and 2N.
• Experience working with commissioning authorities, consultants, contractors and equipment vendors.
