I'm currently working with one of London's leading organisations to recruit a Network & Security Engineer to join their Network Infrastructure team. This is an excellent opportunity to join a large enterprise environment, supporting a highly connected network across headquarters, branch offices, data centres, and cloud environments, while playing a key role in both infrastructure projects and day-to-day operational support.

You'll be involved in supporting and enhancing enterprise networking, security, and connectivity across the business, working closely with internal teams, third-party suppliers, and key stakeholders.
Key Responsibilities
- Support, maintain, and improve enterprise LAN, WAN, and Wireless infrastructure
- Deliver network infrastructure projects alongside BAU operational support
- Configure, support, and troubleshoot Cisco routing, switching, and wireless technologies

- Troubleshoot complex networking, connectivity, and security incidents
- Work closely with third-party providers, vendors, and internal stakeholders
- Support network upgrades, lifecycle management, and future infrastructure improvements
- Contribute towards SD-WAN and wider network transformation initiatives
