Infrastructure System Administrator(Windows/Linux) (Systems Engineer)

-

General System Management

• Monitor server performance, capacity, and resource utilization using enterprise monitoring tools (e.g., Zabbix, Grafana, Nagios, SolarWinds).
• Perform regular system backups, disaster recovery drills, and data integrity checks.
• Apply security patches, update, and conduct vulnerability assessments across all infrastructure components.
• Optimize system configurations for efficiency, including hardware provisioning and virtualization management (e.g., VMware, Nutanix).
• Maintain comprehensive documentation for system configurations, procedures, and incident responses.

Cloud Infrastructure Management

• Configure and monitor cloud resources (e.g., virtual machines, storage, networking) across public and hybrid environments.
• Assist in hybrid cloud integrations (e.g., directory synchronization, identity-aware proxies) for seamless on-premises to cloud transitions.
• Perform cost optimization reviews and scaling adjustments for cloud workloads.
• Support troubleshooting and resolution of cloud-specific issues, collaborating with cloud architects for advanced deployments.
• Ensure compliance with cloud security and governance policies.

Windows and Linux Server Operations

• Administer Windows Server Environments (installation, configuration, clustering, failover management).
• Manage Linux servers, with a strong emphasis on Red Hat-based distributions (e.g., RHEL, CentOS, Rocky Linux), including shell scripting, package management (yum/dnf), and performance tuning.
• Enforce server hardening and firewall rules, ensuring compliance with CIS benchmarks.
• Automate server provisioning and maintenance using PowerShell (Windows) and Ansible/Bash (Linux).
• Conduct root cause analysis and remediation for server-related incidents.

Active Directory Management

• Manage user and group policies, permissions, and authentication via Group Policy Objects (GPOs) and Azure AD hybrid setups.
• Monitor Active Directory Health Using tools like ADREPLSTATUS; perform regular security and compliance audits.
• Integrate Active Directory with other systems for cross-platform identity management.
• Implement and maintain least privilege access principles and periodic access reviews.
• Support directory migrations, upgrades, and federation services as required.

HCI Environment

• Cluster Deployment: Configure nodes and storage pools for hyper-converged infrastructure.
• Resource Optimization: Balance workloads across nodes for performance.
• High Availability: Implement failover clustering and test disaster recovery scenarios.
• Firmware Updates: Apply updates to HCI hardware and hypervisor software.
• Monitoring: Use vendor tools (e.g., Nutanix Prism, VMware vSAN) for health checks
