Senior Infrastructure Engineer

Senior IT Infrastructure Engineer

Edinburgh or London | Permanent |

We’re transforming how our technology infrastructure is built and delivered - moving from traditional data centres to a modern, secure and scalable hybrid‑cloud environment. As we enter this next chapter, we’re looking for a Senior IT Infrastructure Engineer to help shape and deliver that journey.

This is a role for someone who builds, improves and modernises - not someone who simply maintains. You’ll work across the full infrastructure stack, designing solutions, leading technical delivery, and helping us create the resilient cloud‑ready platform that supports the future of our business.

What you’ll be doing

• Designing and delivering the next stage of our hybrid network and cloud architecture.
• Modernising legacy infrastructure and leading migration and transformation projects.
• Building and improving Azure infrastructure, connectivity and landing zones.
• Designing IAM, security and policy controls across cloud and on‑prem environments.
• Troubleshooting complex infrastructure and network issues.
• Working closely with Security, Architecture, Cloud and Application teams to turn strategy into practical solutions.
• Automating infrastructure and reducing manual processes.
• Improving resilience, monitoring, performance and operational efficiency.
• Providing senior technical input during major incidents when required.

What we’re looking for

• Strong enterprise infrastructure and networking experience.
• Deep knowledge of LAN/WAN, routing, switching, DNS, DHCP, VPNs, firewalls and network security.
• Solid experience with servers, virtualisation, storage, compute and data centre environments.
• Hands‑on experience designing and implementing Azure infrastructure.
• Experience building hybrid connectivity between on‑premises and cloud.
• Strong understanding of IAM, RBAC, privileged access and least‑privilege models.
• Experience with cloud governance, policy and security controls.
• Proven delivery of infrastructure projects, migrations and transformation programmes.
• Ability to produce technical designs, architecture documentation and implementation plans.
• Understanding of resilience, disaster recovery and business continuity.
• Experience working in regulated environments (financial services advantageous).
• Someone who challenges, builds and improves - not just maintains.
