Global Network Architect – London. Full‑time, hybrid. Design and lead the evolution of a next‑generation, software‑defined, cloud‑integrated global network, advancing SASE, Zero Trust, SD‑WAN, and cloud‑native networking.
Responsibilities
- Architecture & Strategy – Lead design and implementation of enterprise network architecture, including LAN, WAN, cloud, edge connectivity, and smart spaces.
- Drive transformation from traditional networking to SD‑WAN, SASE/Zero Trust, and cloud‑native networking.
- Define standards for secure, scalable, highly available network designs across global environments.
- Partner with business and technical stakeholders to align architecture with company initiatives and growth.
Network Engineering & Operations – Oversee and maintain large‑scale enterprise networks. Cisco Catalyst (campus/core switching) and Cisco Meraki (cloud‑managed networking, SD‑WAN, wireless). Internet connectivity, routing, VPN solutions, and venue wireless technologies (Wi‑Fi, BLE, DAS). Architect and support Layer 2/3 and Layer 4–7 services, including BGP, EIGRP, STP, load balancing, and traffic engineering. Design and optimize secure remote access using IPsec, SSL VPN, and Zero Trust approaches. Security & Zero Trust – Integrate network security into architecture. Apply Zero Trust Network Architecture using Zscaler and similar platforms. Implement secure web gateways, cloud firewalling, and identity‑aware access controls. Ensure compliance with security best practices and enterprise policies; collaborate closely with data security teams. Automation & Observability – Drive automation and infrastructure‑as‑code. Use Python, Ansible, and APIs to build and enhance monitoring, telemetry, and analytics platforms. Track network performance, capacity, and utilization trends; implement self‑healing operational processes. Leadership & Collaboration – Act as a technical authority and mentor, providing hands‑on support, proof‑of‑concept development, and design validation. Collaborate cross‑functionally with cloud, security, and application teams. Promote innovation and continuous improvement across teams. Qualifications
