Mechanical Maintenance Engineer in Slough, Berkshire

Mechanical Maintenance Engineer

Slough | Data Centre | 4 on, 4 off | 12-hour shifts

£50,000–£60,000 + 10% shift allowance + bonus + private medical + pension + holiday

Join the on-site engineering team at a live data centre in Slough. You’ll carry out planned and reactive mechanical maintenance across four data halls, with a particular focus on liquid cooling systems and the wider building services infrastructure that keeps the site running.

Uptime, response times, safety and accurate documentation all matter in this environment. You’ll follow site procedures, keep clear maintenance records and respond promptly to faults and alarms.

What you’ll be doing

• Carrying out planned preventative maintenance (PPM) and reactive maintenance across the data centre.
• Maintaining liquid cooling systems serving live data halls.
• Working on chilled water systems, pumps, valves, pipework, pressurisation units, AHUs, FCUs, CRAC and CRAH units, and associated mechanical plant.
• Monitoring plant performance, identifying developing faults and responding to alarms, breakdowns and urgent maintenance requirements.
• Supporting water treatment, temperature control, cooling performance and mechanical compliance.
• Completing logbooks, PPM records, permits and maintenance reports accurately.
• Supporting isolations, shutdowns, risk assessments and method statements as required.
• Working with the shift team, site management, specialist subcontractors and client representatives, including coordinating and escorting contractors on site.
• Maintaining high standards of health and safety, housekeeping and site procedures, and helping improve plant reliability and resilience.

What you’ll need

• Experience as a Mechanical Maintenance Engineer, Shift Engineer, Critical Facilities Engineer, Data Centre Engineer or Building Services Engineer.
• A recognised mechanical qualification, such as an NVQ, City & Guilds, a mechanical apprenticeship or equivalent.
• A strong mechanical background, with hands-on experience across cooling systems, chilled water, pumps, valves, pipework and building services plant.
• The ability to work a 4 on, 4 off pattern of 12-hour shifts.

Data centre experience would be a strong advantage. Experience from hospitals, banking, pharmaceutical sites, laboratories, telecoms, industrial facilities or large commercial buildings is also relevant.

Liquid cooling experience would be a major advantage, and engineers with strong critical cooling experience will also be considered. Familiarity with permit-to-work systems, RAMS, PPM systems, compliance records and subcontractor coordination would be useful.

The right person

You’re reliable, practical and calm under pressure. You communicate clearly, follow procedures and take ownership of your work as part of a shift team. This is a permanent role for an engineer who wants to build experience with liquid cooling and critical infrastructure on a live data centre site.
