Work pattern: Office Based, Telford
About The Role
Our Network Architects own the architecture, design and documentation of the Entanet ISP network as it separates from City Fibre and stands up as an independent B2B aggregation network.
You will be part of a team of two architects and lead the network architectural workstreams underpinning TSA migration, colocation and backhaul rationalisation, and broadband re-platforming.
You shall also lead and support a team of network engineers who help execute workstreams.
Beyond the network separation, this role translates business and product requirements into robust, well-documented network designs across Ethernet, broadband, PWAN and colocation.
Key Responsibilities
- Lead Transitional Service Agreement (TSA) network migrations workstreams, and the tasks required to establish Entanet as an independent network from City Fibre.
- Lead on RIPE LIR and database administration, and the migration of IP resources from City Fibre to Entanet.
- Lead IPAM replacement and migration from City Fibre’s Net Box.
- 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 e BGP and separation from City Fibre’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 City Fibre 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.
About You
- Proven experience designing and documenting carrier or ISP networks at architecture level, distinct from operational NOC delivery.
- Strong working knowledge of BGP, IS-IS, MPLS and IP transit/peering across a multi-site backbone.
- Experience producing HLD/LLD and governing IP addressing and routing strategy.
- Understanding of Ethernet, broadband, PWAN, security and colocation products and the supplier landscape (carriers, backhaul providers, colocation).
- Excellent technical documentation and diagramming ability.
- Strong analytical and problem-solving skills with the ability to assess trade-offs across cost, resilience and capacity.
- Able to work across product lines and balance competing architectural priorities.
- Comfortable adopting AI-assisted tooling to accelerate design and analysis.
- 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), City Fibre and Openreach products.
- Experience exposing network services as APIs for portal/automation consumption.
Qualifications
- Right to work in the UK.
- Full UK driving licence.
