• Witness and perform functional tests, pre-commissioning checks, loop checks, instrument calibrations, and system integration tests; record results and raise NCRs/RFIs as required.
• Verify equipment installation, alignment, and readiness; ensure tagging, tagging, and documentation accuracy for as-built records.
• Support DCS/PLC configuration, logic verification, IO checks, and interface testing; collaborate with control engineers for safe start-up sequences.
• Execute performance tests and assist with system tuning, troubleshooting, and optimization during commissioning and ramp-up.
• Ensure HSE compliance during commissioning: permit-to-work, risk assessments, method statements, toolbox talks, and safe isolation procedures.
• Manage commissioning schedules, identify risks/delays, and propose recovery actions to meet project milestones.
• Coordinate vendor inspections, witness FAT/SAT, review loop diagrams, datasheets, and factory test reports.
• Capture and close commissioning punch-list items; produce commissioning reports and lessons-learned documentation.
• Train operations/maintenance teams on system operation, emergency procedures, and maintenance requirements; hand over documentation and spares lists.
• Support final handover and post-commissioning support (warranty period troubleshooting, performance verification).

• 3–7+ years commissioning experience in relevant sector (oil & gas, power, petrochemical, utilities, industrial), adjustable by seniority.
• Hands-on experience with commissioning procedures, loop checks, FAT/SAT, IO verification, and site start-up activities.
• Familiarity with PLC/DCS systems, control logic, HMI, and basic automation troubleshooting.
• Strong understanding of mechanical/electrical installation practices, instrumentation, and testing/calibration.
• Knowledge of industry standards and codes relevant to sector (API, IEC, ASME, NEC, or local equivalents).
• Competence in preparing and reviewing technical documentation and commissioning reports.
• Excellent communication, coordination, and problem-solving skills; ability to work under schedule pressure.
• Willingness to work onsite, including possible shift/rotational patterns and travel to remote or offshore locations.

Preferred

• Experience with specific tools/software: AutoCAD, SmartPlant, MS Project, commissioning/test management tools.
• Certifications: safety/permit training (e.g., NEBOSH, IOSH), offshore survival (BOSIET), or relevant sector qualifications.
• Prior experience with HVAC, fire alarm/suppression systems, building services, or specialized process equipment depending on project type.
