Infrastructure Engineer

Company: The ONE Group Ltd
Apply for the Infrastructure Engineer
Location: Peterborough
Job Description:

If you’re the person everyone turns to when things get tricky, the firewall won’t behave, the migration’s wobbling, the network’s doing something strange then this is probably your kind of role.

We’re looking for a solid 3rd line engineer. Someone comfortable being the final escalation point. Someone who’s led migrations before. Someone who understands SMB networks inside out, not just in theory, but in the real world.

What you’ll be doing:

  • Handling the complex stuff that can’t be fixed at 1st or 2nd line
  • Leading Microsoft 365 and Azure migrations
  • Configuring and troubleshooting WatchGuard firewalls
  • Working across VLANs, VPNs, Wi-Fi deployments, routing, switching
  • Supporting and improving Windows Server environments
  • Delivering upgrades, rebuilds and infrastructure projects
  • Talking directly to clients (and explaining things in plain English)
  • Supporting junior engineers when they need help

The tech stack:

You’ll be hands-on with:

  • Windows Server, AD, Group Policy
  • Hyper-V
  • Veeam
  • WatchGuard firewalls
  • RMM tools (N-Able or similar)

What we’re really looking for:

  • 5+ years in IT support
  • Solid experience in a true 3rd line or infrastructure-focused role
  • Strong WatchGuard firewall experience
  • A strong grasp of SMB networking and troubleshooting
  • MSP experience — you’re used to juggling priorities
  • Comfortable speaking to clients at all level

Most importantly, you’ll have real ownership. You won’t be micromanaged, and you won’t just be another name on a rota.

If you’re a strong 3rd line engineer who wants more control over projects, more technical depth, and more say in how things are done then lets talk. Apply today and one of our team contact you to discuss the role in more detail should you application be considered.
