Data Centre Facility Engineer, Data Centre Engineering Operations Location: LONDON, United Kingdom (Onsite) Role Overview Our organization is seeking a mechanically-biased Engineering Operations Technician to join our team. This hands-on role is focused on the installation, maintenance, and troubleshooting of mechanical cooling and water systems infrastructure across our data centre portfolio. The ideal candidate must have a data centre background and will work directly with air handling units, chillers, cooling towers, and associated water treatment plant. This is a shift-based role requiring flexibility to support 24/7 operations. Key Responsibilities * Install, maintain, and repair pipework, fittings, valves, and manifolds across cooling distribution loops and water circuits. * Operate and maintain air handling units (AHUs), chillers, cooling towers, evaporative cooling systems, and liquid cooling infrastructure. * Perform pressure testing, leak detection, and system integrity checks on pressurized water circuits. * Manage water treatment programs in line with ACOP L8 and HSG274 requirements. * Maintain and troubleshoot pumps, heat exchangers, coolant distribution units (CDUs), and associated mechanical components. * Monitor thermal performance of cooling systems to optimize flow rates and energy efficiency. * Support commissioning and decommissioning of mechanical cooling infrastructure. * Perform routine preventive maintenance on mechanical assets. * Respond to alarms and incidents related to leaks, pressure anomalies, or thermal exceedances. * Maintain accurate records of maintenance activities, water treatment logs, and system parameters. * Collaborate with controls engineers on BMS/SCADA integration for mechanical plant monitoring. * Adhere to all site safety procedures including permit-to-work and LOTO. Required Qualifications * Must have data centre background. * Demonstrable experience working with pressurized water systems, pipework installations, and fluid distribution networks. * Knowledge of mechanical systems (Mechanical, HVAC systems, Controls). * Experience reading and writing procedures, technical documents, and engineering drawings. * Knowledge of generic mechanical room infrastructure such as chillers, cooler units, and fan controls. * NVQ Level 3 in Mechanical, Electrical or Mechatronics, or NFQ Level 3 (or equivalent). * Knowledge of ACOP L8 and HSG274 guidance, with experience implementing compliant water treatment regimes. * Practical understanding of fluid dynamics principles including flow rates, pressure drop, and heat transfer. * Ability to work a flexible schedule, including weekends, nights, and holidays. Preferred Qualifications * Experience with EPMS/SCADA/BMS controls system software or hardware. * Direct experience with liquid cooling technologies such as CDUs or rear-door heat exchangers. * City & Guilds 2079 or equivalent Legionella control qualification. * Knowledge of water treatment processes including closed-loop and open-loop system management. * IOSH Managing Safely or NEBOSH General Certificate. * Experience with commissioning or decommissioning of mechanical systems. * Understanding of cooling architectures and thermal management principles. * Preferred backgrounds include construction, banking, or manufacturing/factory environments.
