• Operational Excellence: Monitor, optimise, and support cloud infrastructure, ensuring high availability and performance. Contribute to incident response, root cause analysis, and continuous improvement.
• Collaboration & Documentation: Work closely with architects, developers, and security teams to deliver integrated solutions. Produce clear technical documentation, including LLDs, runbooks, and standards to be handed over to the BAU Support teams.
