Job description

Job Purpose

The Senior Electrical Commissioning Technician leads field execution teams in pre-commissioning, functional testing, cause & effect verification, and safe energization of MV/LV power distribution systems. Operating within a high-pressure EPC environment, this role oversees field isolation protocols, coordinates PTW activities, and ensures all electrical equipment and loops meet strict project safety and engineering specs.

Key Responsibilities & Core Scope

• MV/LV Pre-Commissioning & Commissioning:
  • Lead pre-commissioning and dynamic commissioning of Medium Voltage (MV) and Low Voltage (LV) distribution systems.
  • Conduct testing, inspection, and operational verification of Switchgear, Transformers, Motor Control Centers (MCCs), and Uninterruptible Power Supply (UPS) systems.
• Loop Checks, Cause & Effect, & Functional Testing:
  • Execute end-to-end electrical loop checks, interlock verifications, and complete functional testing from field devices to the control room.
  • Perform Cause & Effect (C&E) logic testing for electrical trips, interlocking schemes, auto-transfer systems, and emergency shutdown integration.
• Energization Activities:
  • Prepare equipment, review safety boundaries, and directly execute high-risk MV/LV energization procedures in line with approved Commissioning Test Procedures (CTPs).
  • Oversee primary/secondary injection testing, breaker timing, and phase rotation checks prior to live power handover.
• Permit-to-Work (PTW) & Field Execution:
  • Act as the Performing/Isolating Authority for electrical Permit-to-Work (PTW) applications, Job Safety Analyses (JSAs), and safe Lockout/Tagout (LOTO) isolations.
  • Supervise field technicians and subcontractor teams to maintain safe execution on site.
  • Validate test dossiers, clear punch list items, and record red-line markups on Single Line Diagrams (SLDs) for final system completion.

Desired Candidate Profile

• Education: Diploma, Higher National Diploma (HND), or Trade Certificate in Electrical Engineering.
• Experience:
  • 8+ years of hands-on electrical pre-commissioning and commissioning experience on major EPC projects (Oil & Gas, Petrochemical, Power, or Heavy Industrial plants).
  • Demonstrated senior-level experience leading MV/LV switchgear energization, UPS systems testing, and complex Cause & Effect verifications.
  • Proven track record working under strict Permit-to-Work (PTW) and safe electrical isolation systems.
• Certifications (Preferred):
  • CompEx (Ex01-Ex04) certification for hazardous area equipment.
  • HV/MV Switching License or Authorized Senior Electrical Person certification.
