• Ensure full FGAS compliance, including correct handling and record-keeping of refrigerants
• Diagnose faults efficiently and achieve first-time fixes where possible
• Undertake working at height activities, including climbing, as required (full training and certification provided)
• Carry out general site maintenance tasks, supporting overall asset condition and performance
• Complete basic fabric repairs (e.g. minor building works, upkeep, and remedial tasks)
• Ensure all work is completed in line with health & safety standards and company procedures
• Provide clear and accurate job reporting and documentation
• Support other engineering disciplines as required, contributing to a flexible, multi-skilled team environment

• FGAS qualified (Category 1 essential)
• Strong fault-finding and diagnostic capability
• Experience working on large-scale systems (including units over 5 tonnes)
• Comfortable working at height or willing to undertake training
• Experience in general maintenance and/or fabric repairs desirable
• Full UK driving licence

What We’re Looking For

• Strong focus on quality, safety, and compliance
• Someone who takes ownership and pride in their work
• Ability to balance specialist AC work with wider site responsibilities
• Team player who can support and collaborate across functions

Why This Role Matters

This is a critical, multi-functional role that supports both our specialist compliance requirements and broader site operations across Scotland. By bringing this capability in-house, we reduce reliance on external contractors, improve responsiveness, and strengthen overall service delivery.
