Senior Service Assurance Manager

Summary

The Senior Service Assurance Manager is a key role within D&T responsible for Service Management delivery assurance across their assigned business Domain(s), product areas, platforms, or infrastructure services.

Assigned to and embedded within the relevant D&T Domain(s), you will provide the primary link between Service Management practices, domain leadership, product teams, engineering teams and service owners; ensuring Service Management practices are embedded, complied with, and that IT Services are meeting the service levels required by business operations and stores.

As an ambassador for Service Management, you will promote ITIL4, DevOps, and SecOps as complimentary frameworks, working with the various product and platform owners, squad leaders and their teams to support them to effectively balance velocity and throughput needs with the standardisation and risk reduction and operational stability achieved through adherence to the Service Management Practices.

This role will proactively monitor performance levels, identifying trends, risks and issues, and will work collaboratively with relevant Domain leaders, product and engineering teams, and service owners to develop insights, establish root causes, and plan and track the implementation of required improvement initiatives and interventions.

The Senior Service Assurance Manager is accountable for the Service Management performance achieved across the assigned Domain(s) and will be able to demonstrate increased performance, maturity and operational stability over time.

Work with Service Management Practice Owners to assure and mature Service Management practices, ensuring they are consistently defined, measured, improved and embedded into day-to-day delivery.

This role requires regular engagement with Domain leadership, product and engineering teams, service owners and key business stakeholders to understand current challenges and risks, reinforce the value of Service Management practices, and secure alignment, buy-in and sponsorship for improvements.
