Job Summary:

Concentrix is seeking a skilled and proactive Systems Administrator with a strong focus on Linux server administration and experience across Windows Server, virtualization, storage, and cloud technologies. In this role, you will be responsible for maintaining and optimizing a hybrid infrastructure environment, including on-premises VMware, enterprise backup solutions, SAN/NAS storage, and cloud platforms such as Azure and AWS.

Key responsibilities include server patching, performance monitoring, automation through scripting (Bash, Python, PowerShell), and implementing security best practices. You will also support database environments in collaboration with DBA teams and participate in ITIL-based operational processes including incident, change, and problem management.

This is a full-time, on-site position that requires participation in on-call rotations and after-hours maintenance as needed.

Key Responsibilities

• Administer and support Linux server estates (primary focus) and Windows Server (secondary), ensuring availability, security, and performance.
• Manage on-prem virtual infrastructure: VMware vSphere/ESXi and vCenter—provisioning, templates, snapshots, resource optimization.
• Operate enterprise backup and recovery platforms (e.g., Veeam, Commvault, NetBackup): job configuration, monitoring, restores, and DR testing.
• Support storage systems: SAN/NAS administration (LUN provisioning, zoning, multipathing) and fibre channel switches (e.g., Brocade/Cisco MDS).
• Support hybrid cloud infrastructure (Azure/AWS/GCP) for IaaS compute, storage, networking, and workload migrations.
• Collaborate with DBA teams to support MS SQL Server, Oracle, and Sybase: patching, backup/restore, service availability, and performance basics.
• Execute OS/application patching and upgrades (yum/dnf/apt/Windows Update/WSUS), kernel updates, and hardware/firmware maintenance windows.
• Monitor health and capacity (e.g., Prometheus, Grafana, Zabbix, Nagios); analyze performance and perform root-cause analysis for incidents.
• Automate routine tasks with Bash/Python/Ansible and PowerShell for Windows; create and maintain repeatable runbooks.
• Harden systems per security baselines (e.g., CIS), manage IAM (AD/LDAP), certificates, encryption, vulnerability remediation, and audit logging.
• Participate in incident, problem, and change management (ITIL), including on-call rotations and after-hours maintenance as required.
• Maintain documentation, diagrams, asset inventories, and knowledge articles; mentor peers and share best practices.

Required Qualifications

• 3+ years of hands-on Linux administration in production environments (RHEL/CentOS/Oracle Linux/Ubuntu).
• 2+ years of Windows Server administration (AD/Group Policy, basic roles/features).
• Practical experience with VMware vSphere/ESXi and vCenter.
• Experience with enterprise backup platforms (e.
