Job Description

We're working with a leading organisation operating who are looking to strengthen their Technical Operations team with an experienced Network Engineer.

This is a hands-on role where you'll be responsible for the implementation, support and ongoing improvement of network infrastructure across WAN, LAN, Wi-Fi and firewalls, covering datacentres, Azure and office/depot environments.

You'll work closely with internal technical teams, Cyber Security, project teams and external service partners, acting as a key escalation point for network issues and helping to ensure the organisation's network remains secure, reliable and performing at its best.


What You'll Be Doing
  • Implementing and supporting network infrastructure across WAN, LAN, Wi-Fi and firewalls.
  • Managing and supporting Cisco ACI, Cisco FMG and the Fortinet ecosystem.
  • Working with Azure networking, including VNets, NSGs and VPN gateways.
  • Reviewing technical designs and providing guidance to ensure solutions meet security policies and industry standards.
  • Managing network security across firewalls, IDS/IPS, VPN, NAC and network segmentation.
  • Working alongside the Cyber Security team on vulnerability remediation, risk assessments and threat intelligence.
  • Acting as an escalation point for complex network incidents and helping minimise disruption to IT services.
  • Working with internal stakeholders and external service providers on network changes, roadmaps and delivery.
  • Monitoring network performance and identifying opportunities to improve reliability, performance and efficiency.
  • Maintaining accurate network configurations, topologies and technical documentation.
  • Supporting the integration of new networking technologies into the existing infrastructure.
  • Identifying opportunities for automation and reducing manual network configuration activities.

What We're Looking For

We're looking for someone with strong hands-on network engineering experience who can operate comfortably across networking, security and cloud environments.

You'll bring:

  • Strong knowledge of Cisco routing and switching.
  • Proven experience with Cisco ACI and Cisco FMG.
  • Strong experience across the Fortinet ecosystem.
  • Good understanding of TCP/IP, DNS, DHCP, VPNs, VLANs and network segmentation.
  • Experience configuring and managing network firewalls, IDS/IPS, VPN and NAC technologies.
  • Experience with routing protocols such as BGP and switching technologies including STP and VLANs.
  • Experience working with Azure networking, including VNets, NSGs and VPN gateways.
  • Strong troubleshooting and problem-solving skills, with experience acting as an escalation point for network issues.
  • Experience working with internal stakeholders, technical teams and external service providers.
  • The ability to work under pressure and support major incidents where required.

We'd Be Particularly Interested If You Have
  • CCNA or equivalent certification.
  • AZ-700 / Microsoft Azure Networking certification.
  • Experience working with NAC.
  • Experience with network monitoring platforms such as SolarWinds.
  • Experience with network automation and scripting.
  • Experience working within a CNI, regulated or similarly security-conscious environment.

Why This Role?

This is an opportunity to join an expanding Technical Operations function and have a genuine impact on the security, availability and performance of a critical network environment.

You'll have exposure across networking, security, Azure and infrastructure, while working closely with Cyber Security, Architecture, Projects and senior technical stakeholders.

If you're a Network Engineer who enjoys solving complex technical problems, improving network environments and working across both operational and project-based challenges, we'd be keen to hear from you.
