Network Engineering Specialist

Our client is one of the UK's most recognised and influential communications organisations - a household name that keeps the country connected and is right at the heart of the nation's digital infrastructure. This isn't a small fish; this is a business that operates at serious scale and is actively shaping what comes next in networking and technology. The Engineering team works across a wide variety of platforms and technology stacks, maintaining and developing both bespoke and off-the-shelf capabilities for some incredibly demanding customers. The team is London-based, collaborative, and built around a genuine culture of technical excellence - if you're the kind of engineer who wants to work on complex, meaningful problems with smart people around you, this is the place.

Exposure to SD-WAN, automation tooling like Ansible or Terraform, and third-line support for complex IP networks will put you right at the front of the queue.
