Own the high-level design, dimensioning guidelines and standard configurations for Service Layer Architecture across the European cluster. Analyse local operating company requirements and existing architectures to develop viable, scalable and future-ready network solutions. Design solutions for Broadband Network Gateways, CGNAT, AAA, IP allocation, traffic and policy management, lawful interception, and accounting data platforms. Apply a “design once, deploy many” approach to encourage reuse, consistency and efficient deployment across European markets. Support local operating companies in documenting consistent technical requirements aligned with architecture, budget and future technology needs. Produce high-quality high-level designs and ensure an effective handover to delivery teams, including support for low-level design, testing and first-office application activities. Define network dimensioning rules based on resilience requirements, capacity needs and supplier capabilities. Collaborate with network technology and architecture teams and contribute technical requirements to supplier request-for-quotation processes. Support the identification of network synergies, consolidation opportunities and standardisation initiatives.



Promote architectural harmonisation across multiple European operating companies while accommodating justified local requirements. You are fluent in English and can communicate technical concepts effectively across international teams. You understand fixed access, IP, Ethernet and optical services across backbone and core networks. You have a sound understanding of broadband, cable and IP fundamentals, including the routing protocols that support them. You have proven knowledge of Broadband Network Gateways, subscriber management, PPPoE, IPoE, DHCP and AAA/RADIUS platforms. You have knowledge of IP/MPLS networking principles and routing protocols, including BGP and IS-IS, as applied to broadband and Service Layer architectures. You understand disaggregated BNG architectures and Control and User Plane Separation concepts. You have detailed knowledge of accounting information collection, correlation and data-retention techniques. Experience with software development, virtualisation platforms such as VMware or OpenStack, SDN, NFV or network security would be advantageous. Relevant formal training or certification from organisations or suppliers such as FTTH Council, BBWF, Cisco, Nokia, Huawei or Juniper would be beneficial.
