Design and engineer power and cooling solutions - including UPS topology, PDU configuration, generator capacity, CRAC/CRAH and in-row cooling layouts, airflow management, and hot/cold aisle containment for new-build, expansion, and refurbishment projects. Collaborate with IT infrastructure and programme teams - ensuring facilities designs and constraints are fully integrated with server, network, and storage deployment plans, and that physical infrastructure readiness is not the critical path risk in broader transformation programmes.
