We are proud to recruit an experienced Contract Network Engineer for a vital role within their IT Network Operations team. This is a hybrid position is offering the opportunity to support one of the UK’s most dynamic network environments. The role focuses entirely on Business as Usual (BAU) operations, ensuring the performance, stability and security of the company’s existing network estate across all locations.

The successful candidate will be responsible for the day-to-day support and operational management of a diverse enterprise network infrastructure, which includes Fortinet SD-WAN and FortiSASE technologies, Cisco and Aruba switches, and Meraki wireless deployments. This is not a project-based deployment role, but one that centres around troubleshooting, maintaining and enhancing a large, established network that is critical to daily operations across the business. The estate spans a broad range of sites and services, requiring a methodical and proactive approach to monitoring and performance optimisation.

The role demands a strong understanding of modern enterprise network environments and proven experience in delivering consistent network support across multiple platforms. You will be working extensively with network monitoring tools such as LibreNMS and HP IMC to maintain visibility, identify potential issues early, and respond to incidents effectively. You will be responsible for the health and performance of IPsec tunnels, routing and switching configurations, and access control policies, while also contributing to capacity planning and continuous service improvement.

In addition to technical support, you will also collaborate closely with third-party providers, external vendors, and internal stakeholders across IT and engineering functions. You will ensure that service requests and incident tickets are properly managed through the ServiceNow platform and that all work is clearly documented using the NetBox inventory management system. Your ability to manage priorities effectively, maintain detailed records, and uphold strong communication lines with both technical and non-technical audiences will be critical to success in this role.

Candidates must have significant hands-on experience with Fortinet’s SD-WAN technology and associated platforms such as FortiManager, FortiAnalyzer and FortiAuthenticator. You should also have in-depth knowledge of Cisco and Aruba network switches and Meraki Wi-Fi infrastructure, combined with a practical understanding of routing protocols including BGP and OSPF. Familiarity with Zscaler cloud-based security services and previous exposure to integrating secure access solutions within a large enterprise would be highly advantageous.

This role offers an exciting opportunity to contribute to the stability and security of a highly visible public service. If you are a skilled Network Engineer with a passion for BAU excellence and a readiness to hit the ground running in a complex, multi-vendor environment, we want to hear from you.

If you have the skills and experience we’re looking for and want to be part of a challenging and rewarding transition programme, apply today!
