Senior Infrastructure Engineer

This role acts as a 3rd line operations subject matter expert and includes responsibility for managing staff and overseeing workloads. You will focus on improving service quality and shifting appropriate work to earlier support tiers.  

You will work as part of a team of Infrastructure Engineers to ensure services are effectively integrated, delivered, and operated. This includes working closely with third‑party suppliers and technical architects to translate architectural designs into reliable operational services. 

You will oversee incidents and problems, liaising with users, colleagues, and third‑party providers. You will also contribute to broader management activities, including service improvements, onboarding new services, problem management, and staff development. 

In this role, you will develop subject matter expertise in specific products and technologies and provide guidance and support to junior engineers.

• Diagnose and resolve technical problems, ensuring that technical solutions continue to meet business requirements taking accountability for actions taken and decisions made.
• Working collaboratively with other providers and teams to deliver an IT service ensuring value for money by assigning tasks and knowledge to earlier resolver groups.

• Maintaining and updating supporting documentation aimed at users, colleagues and other suppliers.
• Managing, coaching and mentoring more junior infrastructure engineers, participating in their appraisal and related performance management processes.
