Senior Infrastructure Engineer (Networking Azure) London / WFH to £90k

Are you a senior, hands-on Infrastructure Engineer with strong networking expertise who enjoys combining technical delivery with change and transformation projects?

You could be joining a growing technology team as they transition towards a more cloud-first, globally aligned infrastructure estate, while continuing to support a complex hybrid environment.

As a Senior Infrastructure Engineer, you'll provide 3rd line technical expertise across Azure, on-premise infrastructure, networking and firewalls, taking ownership of complex incidents, infrastructure changes and transformation initiatives. You'll remain highly hands-on while helping shape how the infrastructure function operates for the future.

What you'll do:

  • Provide senior 3rd line support across Azure, hybrid infrastructure, networking and firewalls
  • Design, implement and support network and cloud infrastructure, ensuring it remains secure, resilient and scalable
  • Lead and deliver infrastructure transformation and change projects as the business moves towards a cloud-first model
  • Troubleshoot complex infrastructure and networking issues, taking ownership through to resolution
  • Manage infrastructure changes within a structured ITIL/service management environment
  • Reduce legacy and on-premise dependencies in line with the wider Technology roadmap
  • Improve automation and scripting to make infrastructure deployments and configuration repeatable, auditable and efficient
  • Work closely with technology leadership, security, service desk and external vendors
  • Provide technical escalation and knowledge transfer to the Service Desk, improving overall team capability
  • Maintain clear technical documentation, runbooks and operational processes

Location / WFH:

You'll join colleagues in the London office twice a week with flexibility to work from home the other three days.

About you:

  • You have experience as a Senior Infrastructure Engineer, ideally within an SME environment
  • You have advanced, hands-on networking skills, covering routing, switching, firewalls, VPNs and network security - they use Fortinet, but Cisco experience is fine if you're happy to cross train
  • You have strong experience with Azure and hybrid cloud infrastructure
  • You have experience of delivering infrastructure change, transformation or migration projects
  • You're comfortable working across both cloud and on-premise environments
  • You have strong troubleshooting and problem solving skills
  • You have a good understanding of ITIL / structured change management environments
  • You're collaborative with experience of communicating with various vendors, stakeholders and technical teams
  • Experience with PowerShell scripting or infrastructure automation would be beneficial but not essential

What's in it for you:

  • Salary to £90k
  • Pension, Private Healthcare, Life Assurance
  • Employee Assistance Programme
  • 25 days holiday plus 3 for Christmas break
  • Hybrid working (x3 days WFH)
