• Server and Virtualization Administration Install, configure, and maintain physical servers and virtualization platforms including VMware ESXi, vCenter, Microsoft Hyper-V, and Nutanix AHV. Provision and manage virtual machines, templates, snapshots, and resource pools.
• Directory Services and Identity Management Administer Active Directory Domain Services, Group Policy Objects (GPO), DNS, DHCP, AD FS, and LDAP integrations. Manage domain joins, OU structure, service accounts, and delegated administration.
• Cloud Platform Operations Deploy and manage cloud resources across Azure, AWS, and Google Cloud Platform for hybrid and cloud-native workloads. Implement IaaS, PaaS, identity federation, and secure connectivity (VPN/ExpressRoute/VPC).
• Networking and Connectivity Configure and troubleshoot Layer 2/Layer 3 networking: VLANs, subnetting, routing, DHCP, DNS, and IP addressing. Support VPNs (site-to-site and client VPN), firewall rules, and network segmentation for building systems and vendor access.
• Security and Perimeter Controls Implement and maintain firewalls, IDS/IPS, endpoint protection, and hardening standards. Manage VPN access, MFA, role-based access control, and patching cadence to protect sensitive systems.
• Backup, DR, and Recovery Design and operate backup and recovery solutions (e.g., Veeam, image-based backups, snapshots). Validate recovery plans, perform restores, and maintain RPO/RTO documentation.
• Monitoring, Logging, and Performance Deploy and maintain monitoring and logging tools (e.g., SolarWinds, Nagios, Prometheus, ELK) to track system health, capacity, and performance. Identify bottlenecks and implement remediation.
• User and Vendor Access Management Manage user accounts, permissions, password policies, service accounts, and vendor access (least privilege). Administer VPN credentials, jump hosts, and secure remote access procedures.
• Troubleshooting and Incident Response Diagnose and resolve server, virtualization, storage, network, and application issues. Participate in incident response, root cause analysis, and post‑incident remediation.
• Documentation and Change Control Maintain technical runbooks, network diagrams, configuration baselines, and change logs. Follow ITIL‑aligned change control and configuration management practices.
