• Help maintain service availability, performance and capacity through monitoring, troubleshooting and proactive maintenance.
• Support containerised services and the underlying infrastructure they rely on.

Maintenance and lifecycle management

• Carry out routine maintenance activities including patching, upgrades and health checks.
• Support the ongoing management of hardware and software lifecycles to keep services secure and supportable.
• Maintain clear technical documentation and operational records.

Incident resolution and service improvement

• Work with internal teams and, where necessary, suppliers to restore service and address recurring problems.
• Identify opportunities to improve reliability, supportability and efficiency across the platform.
