• Implement and maintain Amazon MWAA (Managed Workflows for Apache Airflow) for orchestration.
• Design and secure API Gateway endpoints for scalable API management.
• Implement secure access controls, encryption standards, and compliance frameworks (e.g., HSM, Key Vaults).
• Ensure tagging and traceability of all cloud assets for governance and cost tracking.
• Collaborate with internal security teams to remediate vulnerabilities and meet compliance targets.
• Ensure high availability and reliability of cloud infrastructure through resilient design and failover strategies.
• Respond to and resolve cloud-related incidents and performance issues.
