• Support Windows environments (~30%), including core services such as Active Directory, DNS, RDS, and Group Policy.
• Design, deploy, and manage infrastructure in AWS (primary cloud) including EC2, VPC, IAM, S3, and CloudWatch.
• Support and maintain infrastructure in GCP environments (Compute Engine, Cloud Storage, IAM), as part of a multi-cloud setup.
• Build and maintain infrastructure as code using Terraform and automate configuration management using Ansible.
• Develop and maintain automation scripts using Bash, Python, or PowerShell.
• Manage virtualisation platforms (VMware, EC2, Compute Engine) and support both physical and virtual servers (HP Proliant, HP MSA).
• Administer and maintain storage systems including SAN/NAS and cloud storage (S3, EBS, Google Cloud Storage, Filestore).
• Configure and troubleshoot networking components across cloud and on-prem environments, including VPCs, VPNs, load balancers, DNS, and firewalls.
• Work with enterprise networking and security equipment (Cisco, Arista, Fortinet, Palo Alto, Juniper, Forcepoint).
• 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).

• Strong hands-on experience with Linux system administration in production environments.
• Experience managing hybrid infrastructure (on-premises + cloud).
• Proven experience with AWS (EC2, VPC, IAM, S3, CloudWatch).
• Hands-on experience with Terraform and/or Ansible for infrastructure automation.
• Solid understanding of networking fundamentals (TCP/IP, DNS, VPNs, load balancing).
