Key Responsibilities You will take technical ownership of the BMS estate across multiple sites, providing engineering support, fault diagnosis, system optimisation and technical guidance to operational teams and specialist contractors. The role will involve commissioning, testing and tuning BMS systems, including control strategies, alarms, trends and system performance. You will manage BMS lifecycle activities such as software upgrades, controller replacements, server and workstation upgrades and platform migrations.

A key part of the role will be maintaining accurate system documentation, including network diagrams, controller drawings, asset registers, configuration records and system baselines. You will work alongside IT and network teams to support BMS connectivity, integration and appropriate network segmentation, including systems connected to plant such as chillers, UPS systems, generators, meters and lighting controls.
