• Identify recurring issues and drive problem management and continuous improvement initiatives.
• Maintain accurate technical documentation, asset records and knowledge articles.
• Collaborate closely with Digital Technology teams and third-party suppliers to ensure service stability and performance.

• Experience maintaining high-quality technical documentation and asset records.
• Experience with problem management, root cause analysis and service improvement initiatives.
• Exposure to major incident management and technical investigations.
• Knowledge of endpoint management and monitoring tools such as Intune, JAMF or similar platforms.
