Key Responsibilities

• Carry out planned preventative maintenance (PPM) and reactive maintenance on commercial refrigeration systems.

• Diagnose faults and carry out repairs on CO₂ refrigeration systems, including transcritical and subcritical systems.

• Maintain and repair refrigeration equipment, including compressors, condensers, evaporators, valves, pipework, and associated control systems.

• Perform component replacements, system checks, pressure testing, leak detection, and performance optimisation.

• Monitor refrigeration system pressures, temperatures, and operating conditions to ensure efficient performance.

• Respond to breakdowns and carry out effective fault diagnosis to minimise equipment downtime..

• Complete maintenance reports, service records, and compliance documentation accurately.

• Ensure all work complies with health and safety procedures, site requirements, and relevant industry regulations.

• Liaise with site management and other engineering teams to maintain reliable site operations.

Essential Requirements

• Hands-on experience working with CO₂ refrigeration systems.

• Strong electrical and mechanical fault-finding and diagnostic skills.

• Experience carrying out planned and reactive maintenance.

• Knowledge of refrigeration controls, compressors, valves, and refrigeration plant.

• Relevant F-Gas qualifications for applicable refrigerants and equipment.

• Good understanding of refrigerant handling, safe working practices, and health and safety requirements.

• Ability to work independently, prioritise workloads, and respond effectively to breakdowns.

Desirable Qualifications & Experience

• NVQ Level 2 or Level 3 in Refrigeration and Air Conditioning, or an equivalent qualification.

• Experience with transcritical CO₂ booster systems and associated refrigeration controls.

• Experience in supermarket refrigeration, cold storage, or large commercial refrigeration.

• Experience with energy-efficient refrigeration systems and performance optimisation.

Working Pattern

• Four days on, followed by four days off.

• Static site-based role, reducing the need for travel between multiple customer sites.

• Shift hours and any night or weekend working requirements to be confirmed.

• Responsibility for maintaining refrigeration systems and responding to breakdowns during scheduled shifts.

Ideal Candidate

The successful candidate will be a reliable, technically competent Refrigeration Engineer with specialist CO₂ experience and a proactive approach to maintenance. You will be confident diagnosing complex faults, carrying out repairs, and maintaining critical refrigeration equipment while ensuring safety, efficiency, and minimal disruption to site operations
