【Main Purpose】
The Commissioning Manager is accountable for commissioning readiness, execution, system turnover and start-up support for the Japan project. The role leads commissioning engineers, contractors and vendors to complete systems safely, on schedule and in accordance with approved procedures.
This is a hands-on leadership role. The manager must read drawings, understand the works, walk the systems, remove blockers early, drive checklist completion and issue clear English reporting without waiting to be chased

■Checklist and procedure control
Drive active completion of commissioning checklists exactly as per approved procedures. Challenge weak evidence, prevent unsupported sign-off and keep the commissioning software live.
■Field execution leadership
Lead daily field walkdowns and test readiness reviews. Verify installation against P&IDs, layouts, vendor manuals, control logic and operating sequence before energization or start-up.
