About the role
Our client is an engineering contractor delivering a green steel facility, and the project is now moving into the commissioning phase. They are looking for a Mechanical Commissioning Engineer to join the team in Castellanza, Italy, from January.
The role centres on testing and commissioning two key areas of the plant: the hydrogen systems and the cooling systems. You will be the lead mechanical voice for this scope, taking systems from construction completion through pre-commissioning and into live testing, and working closely with the wider commissioning, construction and operations teams.
The assignment is expected to run for around six months from a 4 January 2027 start. This is a single position with real ownership. The project team already has colleagues on site, but this skill set is not covered internally, so the successful candidate will have the final say on mechanical commissioning for these systems and be trusted to make decisions independently.
Main responsibilities
- Lead the mechanical pre-commissioning and commissioning of the hydrogen systems
- Lead the mechanical pre-commissioning and commissioning of the cooling systems
- Plan and carry out system walkdowns, checks, flushing, cleaning and pressure and leak testing
- Review P&IDs, isometrics, datasheets and vendor documentation to confirm systems are ready for testing
- Manage punch lists and track the closure of outstanding items
- Prepare, run and sign off commissioning procedures, test records and handover documentation
- Coordinate with construction, electrical, instrumentation and operations teams to sequence activities
- Support vendors and subcontractors working on mechanical equipment during testing
- Enforce site safety requirements, permit to work procedures and safe systems of work
- Report progress, risks and technical issues to the project team
Requirements
- Proven experience as a mechanical commissioning engineer on large industrial or process plant projects
- Hands-on experience commissioning hydrogen systems or comparable high-hazard gas systems
- Experience commissioning cooling water or other process cooling systems
- Strong working knowledge of pre-commissioning activities, including flushing, pressure testing and leak testing
- Ability to read and interpret P&IDs, isometrics and mechanical documentation
- Experience managing punch lists, test records and commissioning handover packs
- A thorough approach to health, safety and permit to work procedures
- Able to take ownership of a scope and make decisions independently
- Able to start on 4 January 2027 and work in Castellanza, Italy
The offer
- Contract position on a green steel project, based in Castellanza, Italy
- Start date of 4 January 2027
- Expected duration of around 6 months
- Technical ownership of the hydrogen and cooling systems
If you are a mechanical commissioning engineer with hydrogen and cooling systems experience, this role offers a clear scope and real responsibility on a major decarbonisation project. Apply below.
