Core Enablers UK Networks Serv Assurance

Mediate across cultures, operating models, and vendor engagement approaches. Ensure technical consistency and alignment between Group standards and local market execution across Voice Core and SDM networks. Translate strategic goals into technical deliverables with cross-functional execution. Identify and mitigate technical and architectural risks during capability build and deployment. Where vendors deliver, provide design assurance—validating technical solutions, network function designs, test plans, and interworking for production readiness. Safeguard engineering rigor through design reviews, compliance checks, integration criteria, and test acceptance. Collaborate across Transport, Data Core, Security, OSS, IT, Operations, and Group Architecture teams. Coordinate vendors and labs for integration, testing, and design gap closure. Align with Group stakeholders on solutions, platform reuse, and service parity across heritage and transformed networks. Drive simplification and cost efficiency via legacy decommissioning and platform consolidation. Embed “Right First Time” principles for timely delivery. Ensure compliance with Group Architecture, Security Policies, and Regulatory Standards.
