• Lead the service assurance process, ensuring all design, development, testing, and release stages are completed and approved prior to deployment.
• Lead the Change Advisory Board (CAB) process, ensuring all service design aspects of proposed changes are adequately defined, assessed, and approved.

• Solid understanding of non-functional requirements, including security, resilience, performance, and scalability.

• Strong governance and documentation skills, with experience supporting formal assurance, approvals, and audits.
• Excellent stakeholder management and communication skills, with the ability to engage effectively with customers, interfacing parties, suppliers, and technical teams.
