  • Assess capability of vendor solutions and offerings to meet business requirements and manage vendor technology delivery.
  • Make technology investment and business asset decisions and assessments based on extensive knowledge of new and emerging technologies.
  • Develop platform specific technology roadmaps that leverage opportunities from evolving and future technologies
  • Lead in the technical project/program management, design, implementation, testing of onboarding PCRF/SAPC applications that support the Network Slicing design and ensure we have the most resilient network possible.
  • Lead in the development and implementation plan of migrating traffic to new VNF/CNF instances in line with the capacity and redundancy requirements designed for each network slice.
  • Conceptualise and realise all aspects of design, development and deployment of technology trials and Proof of Concepts (PoCs)
  • Work with strategic partners and existing Networks and IT teams to support the transition of on boarding design capabilities and skills internally.
  • Contribute to ongoing ePC/5GC automation activities including VNF/CNF lifecycle management workflow development
  • Transition technologies from trials and PoCs into the mainstream networks or for specialised deployments.
