We are seeking a skilled Data Centre Technician (Maintenance) to support the safe, reliable, and efficient operation of our data centre environment. This role is responsible for maintaining critical mechanical, electrical, and building systems to ensure maximum uptime, operational resilience, and compliance with all site standards and procedures.

You will play a key role in preventative maintenance, reactive repairs, monitoring infrastructure, and supporting change control activities across a highly technical facility.

• Carry out PPM (Planned Preventative Maintenance) on critical systems including HVAC, UPS, generators, cooling systems, CRAC/CRAH units, switchgear, and fire systems.
• Respond to reactive maintenance issues promptly, diagnosing faults and delivering effective solutions to minimise downtime.
• Maintain accurate records of all engineering works in accordance with site processes.

• Monitor, operate, and maintain critical plant and building systems, ensuring optimal performance.
• Support load testing, resilience testing, and infrastructure inspections.
• Conduct routine checks on BMS, EMS, and other monitoring systems to identify and escalate issues.

• Assist in troubleshooting and resolving mechanical and electrical equipment failures.
• Participate in incident management, ensuring timely escalation and communication.
• Provide hands-on technical support during change control events (e.g., scheduled shutdowns, equipment swaps, power downs).

• Ensure all work is completed in line with Health & Safety, Environmental, and Data Centre Critical Environment standards.
• Adhere to risk assessments, method statements, and permit-to-work systems.
• Support internal and external audits, ensuring compliance with regulatory and company requirements.

• Maintain up-to-date maintenance logs, asset records, engineering reports, and technical documentation.
• Report plant anomalies, trends, or risks to management for proactive resolution.
• Support continuous improvement initiatives to enhance reliability and efficiency of the data centre.

• Proven experience in maintenance within critical environments, ideally data centres.
• Strong knowledge of mechanical or electrical systems (HVAC, UPS, generators, LV panels, cooling systems).
• Solid understanding of safe systems of work (permit-to-work, risk assessments, MOPs/SOPs).
• Ability to interpret technical drawings, schematics, and O&M manuals.
• Good communication skills and ability to work under pressure.

• Previous experience in data centre, telecoms, banking, or pharmaceutical environments.
• Familiarity with BMS/EMS systems and remote monitoring tools.
• IT literacy (CMMS systems, Microsoft Office, logging tools).

• NVQ Level 3 or equivalent in Electrical, Mechanical, or Building Services Engineering.
• 18th Edition (if electrical bias).
• F-Gas certification (if mechanical/HVAC bias) – desirable.
• Additional data centre or critical environment training is advantageous.
