The Role

This Senior Technical Account Manager & IT Service Delivery Manager role is a strategic leadership position responsible for owning the complete customer relationship and service delivery for critical defence/public sector clients. You will serve as the primary strategic partnership owner and component IT service manager, directly accountable for customer satisfaction, service continuity, and account growth. This is a challenging, high-ownership role that demands someone who takes full accountability for outcomes, drives their team to excellence, and serves as an indispensable strategic partner to our most demanding customers.

Based in Hampshire and reporting to senior DXC leadership, you will own both the customer-facing relationship and the technical delivery of infrastructure services. This dual responsibility—excelling as both a relationship strategist and a hands-on service manager—defines this role. You will combine exceptional stakeholder communication with deep technical acumen, lead cross-functional teams with authority and confidence, and be the trusted voice that clients turn to in moments of complexity or crisis. Your success will be measured by customer advocacy, retention, service excellence, and your ability to expand the account through strategic partnership and demonstrated value.
