About the role

Key responsibilities & impact

Own routing across the global routing estate — design, implement, and operate enterprise routing (BGP, OSPF,), including internet edge, WAN, and inter-site connectivity.
Engineer and operate the Cisco SD-WAN environment (Catalyst SD-WAN / Viptela) — policy design, template management, onboarding new sites, and troubleshooting overlay/underlay issues.
Lead campus networking across the global office and lab footprint — access/distribution/core, wireless, and network access — delivering reliable, secure, high-performance connectivity.
Resolve escalated operational issues (Tier 3/4) — act as the senior escalation point for complex incidents, driving root-cause analysis and permanent resolution.
Deliver new site builds, refreshes, and migrations — produce designs, interconnect matrices, and cutover plans; coordinate with vendors and installation partners through delivery.
Drive network changes through structured change control — plan, risk-assess, and execute changes with appropriate testing, validation, and rollback.
Maintain operational health through observability — use network monitoring and telemetry tooling to detect, diagnose, and pre-empt issues before they impact users.
Contribute to standards, runbooks, and documentation — raise the quality bar for how the team designs, operates, and hands off work.
Mentor junior engineers and share expertise — act as a technical mentor and multiplier across the team.
Support automation and modernisation — partner with automation/SRE colleagues to codify recurring tasks, moving the team from manual operations toward infrastructure as code.
