Network Architect

Location: (London) - HybridContract

We are seeking an experienced Network Architect to review and evolve an established service provider network.

This is a high-impact architectural engagement focused on introducing a Layer 2 wholesale capability into an existing Juniper-based MPLS/EVPN environment.

Architecture consists of:

• Multiple L2 supplier services

• QinQ handoff terminated on Juniper ACX

• LAGs stretched across ACX devices using EVPN-ESI for multihoming

• L2 to L3 handoff via VPWS

• L3 termination on Juniper MX using Dynamic Profiles

• Tier 1 transit and private interconnects for traffic breakout

We are looking for a consultant-level architect to:

• Review the existing ACX/MX EVPN design

• Design a scalable and resilient L2 wholesale model

• Define traffic flow and service separation between L2 and L3 services

• Assess control-plane and MAC scaling implications

• Validate redundancy and failover behaviour (EVPN-ESI, multihoming)

• Produce High-Level and Low-Level Design documentation

• Provide a phased migration / implementation strategy

This is not a BAU operations role. We have strong operational capability in-house. We require deep architectural and service provider design expertise.

• Strong Juniper MX and ACX experience

• Deep understanding of EVPN (including ESI / multihoming)

• MPLS and L2
  
  VPN (VPWS) in service provider environments

• Experience designing wholesale or carrier L2 services

• Control-plane scaling and broadcast domain design considerations

• ISP / carrier / wholesale network background
