The Customer Success Manager is the senior operational and relationship lead for one or more of CyrusOne's hyperscale customers across our European portfolio. The role owns the end-to-end, post-delivery service experience for those customers, bringing together Operations, Service Delivery, Compliance, Security, Implementation, Sales and Finance so that service is delivered in line with contractual commitments and the customer's expectations.
Working in a matrix organisation, the post holder leads through influence rather than line authority. They govern service performance, manage escalations, monitor overall customer health and drive continuous improvement, so that CyrusOne remains a trusted partner able to support the customer's continued growth at scale.
