Establish and govern topology accuracy, relationship integrity, metadata and engineering standards, aligned with enterprise architecture, security and data governance. Drive service and topology capabilities from engineering through validation into sustained production use, with clear ownership and measures of coverage, accuracy and cost. Influence senior stakeholders on model priorities, topology standards and investment decisions, while managing strategic technology and delivery partners. Build and lead a high-performing service and topology engineering capability, developing people through coaching and structured knowledge transfer. What makes you perfect for the role? Extensive leadership experience across telecommunications, service assurance, topology engineering, OSS, inventory or large-scale technology environments. Demonstrated experience leading enterprise-scale service modelling, topology, inventory or dependency engineering across complex operational environments. Strong knowledge of service topology, inventory relationships, dependency modelling, service impact analysis, APIs and dynamic synchronisation patterns. Strong understanding of network and service architectures and the role of topology in service assurance, analytics, AI and automation. Proven ability to define capability strategy, engineering standards and roadmaps, and translate them into measurable operational outcomes. Demonstrated ability to lead cross-domain teams, influence senior stakeholders and explain complex service and topology concepts clearly. Strong commercial, financial and vendor management capability, including investment prioritisation and value realisation.
