Commissioning Supervisor – Cryogenic Hydrogen Liquefaction

We are looking for a Commissioning Supervisor to join the commissioning team of a prototype plant dedicated to testing liquid hydrogen (LH2) liquefaction technologies for an R&D organization. You will support the start-up and commissioning phase in a shift-based organization (3x8), working within an existing team and contributing to safe, structured, and transparent execution.

As part of the start-up phase, you will be deployed on shift to:

• Support commissioning and start-up activities on a cryogenic hydrogen liquefaction pilot/prototype
  

• Operate in a team setting where your role may involve supervising pilot operations or ensuring minimal-operation monitoring, depending on the shift position and plant status
  

• Contribute to commissioning readiness, functional testing, and safe ramp-up to stable operations
  

The role is performed in a shift rhythm (3x8) with a 6 days out of 7 organization.

The main tasks and duties are:

• Supervise and/or support commissioning and start-up activities for a cryogenic LH2/H2 unit
• Perform and document functional checks, loop checks support, and commissioning tests (as applicable)
• Execute tuning and troubleshooting during start-up, including diagnosis of instrumentation/electrical/control issues
• Read and use engineering documentation effectively (P&IDs, wiring diagrams, loop diagrams, etc.)
• Interface with the commissioning team and participate actively in coordination and follow-up meetings
• Ensure strict compliance with safety and operational rules during all start-up activities

The expected deliverables are:

• Daily activity reports recorded in the shift logbook / “cahier de poste” detailing:
  
  • tasks performed
  • issues encountered
  • corrective actions / solutions implemented
• Commissioning documentation kept complete and up to date, including test reports and associated records
• Active participation in coordination routines and progress tracking
• Delivery against agreed schedule objectives and commissioning priorities

Requirements

• 2–5 years of experience in Instrumentation / Operations / Maintenance, preferably in industrial commissioning/start-up environments

• Proven ability to work in start-up / commissioning teams and in shift operations

• Cryogenic unit start-up: expert-level capability

• Tuning & troubleshooting: expert-level capability

• Hydrogen unit start-up: confirmed experience

• Strong ability to read and interpret P&IDs, wiring diagrams, loop diagrams and related documentation

• Electrical fundamentals and practical field understanding (confirmed level)

• Strong safety culture and methodical execution mindset

• Clear reporting habits and discipline in documentation

• Able to integrate quickly into an existing team and operate effectively under shift conditions

• Hands‑on, field‑oriented, and comfortable with dynamic start‑up constraints
