• Participating in the on-call rota for out-of-hours support

• A collaborative team player with excellent attention to detail
• Someone who takes pride in their work and safety standards
• Experience working in a similar role within Planned and reactive maintenance.

Requirements

• A full UK driving licence
• Additional certifications such as IPAF and PASMA are desirable.
