This hands-on role is focused on the installation, maintenance, and 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, and associated water treatment plant. The role demands strong mechanical aptitude with specific expertise in plumbing, pipework, pressurised water systems, and fluid dynamics. You will be responsible for maintaining system integrity, ensuring compliance with ACOP regulations, optimising thermal performance, and 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. ## Related Videos - [Designing Reliable Distributed Systems: Failures, Retries & Idempotency](https://www.wearedevelopers.com/videos/1963-designing-reliable-distributed-systems-failures-retries-idempotency) - [Containers in the cloud - State of the Art in 2022](https://www.wearedevelopers.com/videos/410-containers-in-the-cloud-state-of-the-art-in-2022) - [The Sustainability Race: AI's Promises, Pitfalls and Potential](https://www.wearedevelopers.com/videos/100155-the-sustainability-race-ai-s-promises-pitfalls-and-potential) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Reliable scalability: How Amazon.com scales on AWS](https://www.wearedevelopers.com/videos/983-reliable-scalability-how-amazon-com-scales-on-aws) - [30 powerful AWS hacks in just 30 minutes: Boost your developer productivity](https://www.wearedevelopers.com/videos/1624-30-powerful-aws-hacks-in-just-30-minutes-boost-your-developer-productivity) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Data Analyst Salary in the UK](https://www.wearedevelopers.com/magazine/278-data-analyst-salary-in-the-uk) - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers)
