We are seeking a highly skilled and customer-focused 3rd Line Infrastructure Engineer to join our Service Desk team. This role sits at the heart of our managed service operation, providing advanced technical expertise and ownership in the resolution of complex infrastructure issues across our customer environments.
As a senior escalation point within the team, you will take full ownership of infrastructure-related incidents and service requests raised by our customers.

Working closely with 2nd Line engineers, project teams, and service management, you will play a key role in maintaining service quality and customer satisfaction. Beyond reactive support, you will be expected to identify recurring issues, challenge existing approaches, and contribute to the continuous improvement of our services, tooling, and processes.
This role requires a strong technical foundation combined with excellent communication and problem-solving skills. You will be confident engaging directly with customers, able to translate complex technical matters into clear and actionable updates, and committed to delivering a high standard of service in line with our customer‑first approach.
