Overview
Our client is seeking a visionary, highly technical Network Service Delivery Principal to lead the strategic design, evolution, and governance of a complex enterprise network estate.
This is a senior, hands‑off architecture and leadership role. While engineering teams focus on delivery and operations, this position defines the network blueprint they build from—bridging business strategy and technical execution across on‑prem, cloud, and hybrid environments.
You will architect scalable, automated, and secure network solutions spanning LAN, WAN (including SD‑WAN), cloud (AWS/Azure), and data centres, while driving the adoption of Network DevOps and Infrastructure as Code at an architectural level. Acting as a technical authority, you will guide senior stakeholders, mentor engineers, and ensure the network estate is resilient, programmable, and future‑ready.
