  • Implement and maintain monitoring and observability solutions (CloudWatch, Prometheus, Grafana, Zabbix) to ensure system health and performance

  • Ensure backup, disaster recovery, and data protection strategies are in place and operational (Veeam, AWS Backup, GCP Backup and DR)

  • Enforce security best practices, IAM policies, and compliance standards across hybrid and multi-cloud infrastructure

  • Collaborate with DevOps, Security, Monitoring, and DBA teams to ensure reliable and scalable system operations

  • Maintain clear and up-to-date documentation of systems, processes, and configurations (CMDB)
