Strong organisational skills with the ability to meet deadlines
Commitment to continuous learning and self‑development

Key responsibilities:

Act as the final escalation point for complex technical incidents and service requests
Lead root cause analysis for recurring or high‑impact issues and implement long‑term fixes
Work with project and solutions teams on infrastructure upgrades, migrations, and deployments
Proactively maintain and manage customer IT estates, ensuring security, performance, and accurate documentation
Recommend improvements aligned with best practice and evolving customer needs
Provide technical leadership and mentoring to First and Second Line teams
Create and maintain technical documentation, including diagrams, SOPs, and troubleshooting guides
