• Review technology lifecycle and obsolescence plans and support future replacement strategies.
• Identify opportunities to modernise and optimise WAN services.
• Assess emerging technologies including SD-WAN, SDN, cloud connectivity, secure remote access, network automation and monitoring
  .
• Act as a technical escalation point for WAN architecture and assurance issues.
• Communicate technical risks, recommendations and design decisions to senior technical and non‑technical stakeholders.

We are looking for strong experience across:

• Enterprise‑scale WAN architecture and design
• MPLS, IP networking and routing
• SD-WAN / SDN

• Secure remote access
