Job Description

If you’re a mission critical installation engineer – CRAC units, VRV/VRF systems, pipework, commissioning – and you’ve spent the bulk of your career on installation rather than service, here’s a role worth reading about. Is this you? You’ve been doing installation work long enough to know the difference between a good project and a grinding one. You’re comfortable on live-site CDM jobs – permits, RAMS, working to drawing – and you don’t need someone looking over your shoulder. What you probably want is a step forward: better projects, a clearer path, and a package that reflects what you’re worth. Around 90% of jobs are in live critical environments and the scale is serious. The team installed the back end of 24 CRAC units last year, alongside VRV programmes and chiller projects. Recent work includes 900kW chiller replacements involving crane lifts and 1.2MW water-cooled chiller installs. That’s the level you’d be operating at. Day to day: installing CRAC units, VRV/VRF systems, running and brazing refrigerant pipework, commissioning to manufacturer standard, and working within CDM-regulated frameworks on larger jobs. A project manager handles the programme – you focus on the engineering. There’s also a clear route forward. The intention is to develop the right person into a Project Supervisor position – CDM responsibility, subcontractor oversight, currently paying £65k. They’d rather build someone into it than hire externally. Prove yourself in the first six months and that conversation happens naturally. A specialist mission-critical cooling business with over 20 years in the sector. Around 80% of revenue comes from the data-centre market. Seven consecutive RoSPA Gold Medals for health and safety – unusual for a business of around 50 people, and it tells you something about how the place is run. Engineers are known by name here. It isn’t a volume contractor.
