AWS Infrastructure Services owns the design, planning, delivery
operation of all AWS global infrastructure. In other words, we’re the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power
cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we’re looking for talented people who want to help. Key job responsibilities
Install, maintain, and repair pipework, fittings, valves, and manifolds across cooling distribution loops, chilled water systems, and condenser 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 pressurised water circuits
Manage water treatment programmes in line with ACOP L8 and HSG274 requirements, including legionella risk assessments, temperature monitoring, chemical dosing, and biocide application
Maintain and troubleshoot pumps, heat exchangers, coolant distribution units (CDUs), and associated mechanical components
Monitor thermal performance of cooling systems and identify opportunities to optimise flow rates, delta-T, and energy efficiency
Support commissioning and decommissioning of mechanical cooling infrastructure during capacity additions
Perform routine preventive maintenance on mechanical assets including filter changes, belt replacements, pump seal replacements, bearing inspections, and valve servicing
Respond to alarms and incidents related to leaks, pressure anomalies, thermal exceedances, or water quality deviations within SLA
Maintain accurate records of maintenance activities, water treatment logs, system parameters, and defect logs
Collaborate with controls engineers on BMS/SCADA integration for mechanical plant monitoring
Adhere to all site safety procedures including permit-to-work, LOTO, and working at height protocols
Work safely at all times, following risk assessments, method statements, and safe systems of work (SSOW) for all maintenance and operational activities
Support continuous improvement initiatives to enhance system reliability and reduce mean time to repair A day in the life Diverse Experiences AWS values diverse experiences. Even if you do not meet all of the preferred qualifications and skills listed in the job description, we encourage candidates to apply.

About the team Amazon Web Services Data Center Engineering Operations (DCEO) is seeking a mechanically-biased Engineering Operations Technician to join our team. This hands-on role is focused on the installation, maintenance
troubleshooting of mechanical cooling and water systems infrastructure across our data centre portfolio. And you’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion. (AIS tagline) You will work directly with air handling units, chillers, cooling towers, evaporative cooling systems, liquid cooling distribution
associated water treatment plant. The role demands strong mechanical aptitude with specific expertise in plumbing, pipework, pressurised water systems
fluid dynamics. You will be responsible for maintaining system integrity, ensuring compliance with ACOP regulations, optimising thermal performance
supporting the scaling of cooling capacity as our fleet grows. This is a shift-based role requiring flexibility to support 24/7 data centre operations. You will work alongside electrical and controls engineers but your primary focus is mechanical systems and fluid management.
