3rd Line Support Engineer

IT Service Desk – 3rd Line Engineer

Reports To: 3rd Line Team Leader (Head of IT Infrastructure)

Location: Wilmslow / Hybrid / Remote

Hours of Work: Mon–Fri, staggered start/finish times between 8am and 6pm. Occasional work outside these hours may be required to support change windows or incidents; TOIL applies.

The Role

The IT Service Desk is the single point of contact for all IT services, requests, and incidents. It's a busy, dynamic, fast-paced team supporting Citation Group's multiple business units across the UK, Canada, and Australia.

As a member of the 3rd Line Team, you will be responsible for building, managing, and maintaining company infrastructure across a multi-tenant, multi-country Microsoft 365 and Azure environment. The role of the IT Support team is to ensure colleagues have the technology they need to achieve business objectives — whether in the office or working remotely.

Alongside day-to-day ticket resolution, you'll work on infrastructure projects and change initiatives — from platform migrations to identity and security improvements — balancing planned project work with reactive support.

We're looking for customer-focused engineers to join our IT department, supporting colleagues both in the office and remotely across the UK (and coordinating with Canada/Australia counterparts).

This role suits someone with 3+ years of experience in a similar role.

• Planning, implementing, and optimising cloud and on-prem data storage technologies
• Installing, managing, controlling, deploying, and maintaining infrastructure systems software to meet operational needs and service levels
• Installing and testing, or decommissioning and removing, systems or system components

• Producing and maintaining system, solution, and knowledge base documentation
• Liaising with 3rd party suppliers
• Travel to other offices as and when required
