It would be great if you have any of the following, but it's not essential: * Experience of a network separation, carve-out or large-scale migration programme. * Given Entanet's current estate, strong familiarity with Cisco ASR routers, and Nexus & Catalyst switches would be beneficial. * Relevant networking certification (e.g. CCNP/CCIE, JNCIP/E-SP, or equivalent) desirable. * Exposure to PXC / wholesale broadband platforms (BTW, Giacom), CityFibre and Openreach products. * Experience exposing network services as APIs for portal/automation consumption. Qualifications * Right to work in the UK. * Full UK driving licence. ## Description * Lead Transitional Service Agreement (TSA) network migrations workstreams, and the tasks required to establish Entanet as an independent network from CityFibre. * Lead on RIPE LIR and database administration, and the migration of IP resources from CityFibre to Entanet. * Lead IPAM replacement and migration from CityFibre's NetBox. * Lead colocation, backhaul and network equipment rationalisation assessments - planning and leading optimisation across the 27 colocation sites (BT exchanges & data centres) and backhaul estate. * Lead architecture to separate Entanet's eBGP and separation from CityFibre's network. * Design and document network topology, IP addressing strategy and routing policy (BGP/MPLS/IS-IS) across the core and customer-facing estate. * Produce HLD/LLD for all network changes and new products, maintaining a clear architectural baseline for the business. * Lead architecture of the L2TP broadband product, including migration from BTW to PXC, as well as onboarding CityFibre BFTTP. * Interface with, provide requirements into and support the Systems Infrastructure Engineer on network-related systems (e.g. NMS, RADIUS, SYSLOG, DNS). * Support 'coding the business' by architecting network products as APIs that portals can consume, with high levels of automation. * Use AI-assisted architecture tooling to accelerate diagram production, capacity modelling, HLD/LLD authoring, configuration generation and vendor comparison analysis. * Lead and collaborate with Network Engineers who will lead implementation efforts of LLDs and other BAU network activities. * Act as the highest level of escalation within the network team (Tech Support, NOC, Network Engineers) and available to work to an on-call rota. * Travel to data centres, exchange and other Points of Presence may be required from time-to-time as part of your role. Break-fix and general maintenance visits will be outsourced. ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [Small, Secure, Interconnected: The next Internet Protocol](https://www.wearedevelopers.com/videos/100062-small-secure-interconnected-the-next-internet-protocol) - [Better Together: Leveraging Your Observability Tools as a SIEM](https://www.wearedevelopers.com/videos/2118-better-together-leveraging-your-observability-tools-as-a-siem) - [Transforming Education: A Journey from interactive Markdown to Remote-Labs](https://www.wearedevelopers.com/videos/941-transforming-education-a-journey-from-interactive-markdown-to-remote-labs) - [Your Infrastructure Is Not a Playground: AI Agents for Infra Done Right](https://www.wearedevelopers.com/videos/2084-your-infrastructure-is-not-a-playground-ai-agents-for-infra-done-right) - [Computer Vision from the Edge to the Cloud done easy](https://www.wearedevelopers.com/videos/263-computer-vision-from-the-edge-to-the-cloud-done-easy) ## Related Articles - [UK Business Culture and Etiquette](https://www.wearedevelopers.com/magazine/326-uk-business-culture-and-etiquette) - [IT Salaries in UK](https://www.wearedevelopers.com/magazine/288-it-salaries-in-uk) - [The CAMARA Project: How Telcos Collaborating Improves Developer Experience](https://www.wearedevelopers.com/magazine/671-the-camara-project-how-telcos-collaborating-improves-developer-experience) - [Basic And Advanced Networking in Dart and Flutter](https://www.wearedevelopers.com/magazine/112-basic-and-advanced-networking-in-dart-and-flutter) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
