Job Roles and Responsibilities
- Lead and execute testing and commissioning activities for MV and HV electrical systems including transformers, RMUs, switchgear, and power cables
- Perform pre-commissioning and commissioning tests such as insulation resistance (IR), winding resistance (WR), turns ratio (TTR), contact resistance, tan delta, VLF, AC/DC high voltage testing, and functional checks
- Conduct advanced transformer diagnostic tests including SFRA (Sweep Frequency Response Analysis), magnetizing current, vector group verification, and core balance tests
- Execute protection relay testing, configuration, and programming for various schemes including differential protection, restricted earth fault (REF), overcurrent, earth fault, busbar protection, and line protection
- Perform relay logic verification, secondary injection testing, trip circuit supervision, and end-to-end scheme checks using test equipment such as Omicron, Megger, and equivalent systems
- Carry out testing and commissioning of MV/LV switchgear, circuit breakers, CTs, PTs, CVTs, battery chargers, synchronizing panels, and control systems
- Perform cable testing including continuity, insulation resistance, sheath integrity, and high voltage withstand testing
- Review and interpret SLDs, schematics, protection drawings, and control logic diagrams to ensure correct installation and functionality
- Prepare method statements, inspection test plans (ITP), risk assessments, and detailed test reports in compliance with SEC, IEC, and project specifications
- Coordinate with clients, consultants, and project teams including SEC, Saudi Aramco, Sabic, Maaden, and Royal Commission for approvals, inspections, and system energization
- Lead site activities including troubleshooting, fault analysis, punch point clearance, and final commissioning handover
- Support project execution activities including installation supervision, site engineering coordination, and construction interface
- Assist in estimation, BOQ validation, technical bid preparation, and project planning when required
- Ensure compliance with HSE standards, quality procedures, and project timelines throughout all testing and commissioning activities
Desired Skills

- In-depth knowledge of transformers, RMUs, MV/LV switchgear, and power cable systems
- Expertise in transformer testing including IR, WR, TTR, Tan Delta, SFRA, magnetizing current, and vector group verification
- Proficiency in protection relay testing, configuration, and troubleshooting for schemes such as differential protection, REF, overcurrent, earth fault, busbar, and line protection
- Experience in secondary injection testing, relay logic verification, trip circuit supervision, and end-to-end protection scheme validation
- Hands-on experience with testing equipment such as Omicron (CMC), Megger, Programma, or equivalent tools
- Strong knowledge of pre-commissioning and commissioning procedures including VLF, AC/DC high voltage testing, and functional testing
- Ability to read and interpret SLDs, schematics, control wiring diagrams, and protection logic drawings
- Experience working on industrial and utility projects in Saudi Arabia (SEC, Saudi Aramco, Sabic, Maaden, Royal Commission)
- Familiarity with international standards such as IEC, SEC standards, and industrial best practices
- Ability to independently handle site activities, troubleshooting, fault analysis, and system energization
- Experience in preparing method statements, ITPs, test reports, and commissioning documentation
- Exposure to estimation, BOQ preparation, and technical bid evaluation is an added advantage
- Strong coordination and communication skills with clients, consultants, and project teams
- Knowledge of HSE requirements and ability to work in compliance with safety standards
