Senior Infrastructure Engineer Azure

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 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)
