• Provide Owner's Team leadership at key commissioning interfaces with EPCM, package contractors, OEMs, and operations representatives
• Ensure robust systems completion, punch listing, handover documentation, and acceptance processes
• Champion safe commissioning practices, SIMOPS planning, and compliance with statutory and operational safety requirements
• Coordinate commissioning input to schedules, ensuring alignment with construction completions and critical path activities
• Support development of operating procedures, training, spares, and maintenance strategies in collaboration with Operations Readiness
• Prepare commissioning and start‑up readiness reporting for project leadership and governance forums
