About the Role:
You will ensure the safe, efficient, and compliant start-up of hydrogen production facilities. This includes planning, executing, and validating all commissioning activities across mechanical, electrical, instrumentation, and process systems. Working closely with engineering, construction, and operations teams, you will ensure all systems are installed and tested in accordance with design specifications, regulatory standards, and hydrogen safety protocols. The goal is to deliver a fully operational plant that meets performance, reliability, and environmental targets, ready for handover to operations.
Responsibilities include but are not limited to:
Develop and maintain detailed commissioning plans, schedules, and procedures.
Review engineering designs, P&IDs, datasheets, and specifications to ensure commissioning requirements are incorporated.
Lead the commissioning of mechanical, electrical, instrumentation, and process systems.
Conduct pre-commissioning checks, functional testing, and performance verification.
Ensure all systems are commissioned in compliance with hydrogen-specific safety protocols and environmental regulations.
Prepare and maintain commissioning documentation, including test procedures, checklists, punch lists, and handover packages.
Supervise and coordinate commissioning technicians, contractors, and vendors.
Facilitate training and knowledge transfer to operations personnel.
Enforce strict adherence to hydrogen safety standards, site safety rules, and permit-to-work systems.
Support performance tuning and optimization of systems.
Manage the transition from commissioning to operations, ensuring systems are fully functional and ready for continuous operation.
