Data Centre Engineer

Description

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.
