Job description

Our client, a large organisation with over 5,000 staff, is urgently seeking a skilled and motivated Senior Network Infrastructure Engineer to join their Head Office team in Hertfordshire. This is an exciting opportunity for an experienced engineer with a strong background in network design and multi-site infrastructure, who is also comfortable working across on-premises server platforms and hybrid environments.

You’ll play a key role in designing, maintaining and evolving our network and infrastructure, supporting our multi‑office WAN environment. Your work will include managing routers, switches, firewalls and SAN storage, as well as overseeing Windows Server, Active Directory and VMware platforms. You’ll be actively involved in the transition from current network to enterprise‑grade network solutions such as Juniper, Cisco or Fortinet, which would be highly beneficial.

This role also provides exposure to on‑prem, Azure, Microsoft 365 and hybrid cloud technologies, but your main focus will be on network infrastructure, server environments and WAN connectivity. You’ll be responsible for planning, implementing and optimising network designs to ensure reliability, performance and scalability across multiple sites.

We’re looking for someone who is hands‑on, technically curious and project‑focused, with a proven track record of delivering multi‑office network infrastructure projects. Fortinet, Juniper or Cisco certifications are expected.
