Full job description

Job Description: Linux Server Admin – L2

Job Title: Linux Server Admin – L2

Band: Band 2

Experience: 4 to 8 years

Qualification: Bachelor's degree in computer science, IT, or related field (or equivalent experience)

Location: Chennai (work from Office)

Shift: Rotational shifts, including 24x7 on call/support rotation as per business requirement

About the Role

We are looking for an experienced L2 Linux Server Admin to manage, support, and troubleshoot our Linux-based server environment. The ideal candidate will bring strong, hands-on Linux OS administration skills as the primary requirement for this role, along with working knowledge of virtualization/hypervisor platforms (VMware or Nutanix) as a secondary skill. The candidate will handle day-to-day Linux operations, deep-dive troubleshooting, and platform reliability tasks, working closely with L1 support and L3/Infrastructure Architects, and coordinating with the Hypervisor/Virtualization team where Linux workloads are hosted on virtualized infrastructure.

Key Responsibilities

Linux Server Administration (Primary Skill)

Manage and support Linux server environments (RHEL/CentOS/Ubuntu/SUSE) including installation, configuration, patching, and version upgrades.

Perform day-to-day operations, incident and problem management (L2 escalations from L1), and RCA within defined SLAs for Linux-hosted systems and applications.

Administer user/group management, file system and LVM management, disk/partition management, and storage mount configurations.

Manage core Linux services — SSH, cron/systemd job scheduling, DNS/NFS/Samba, web/application servers, and package management (yum/dnf/apt).

Perform kernel and OS patch management, including patch cycle planning, testing, deployment, and compliance reporting.

Configure and manage high availability and clustering solutions for Linux workloads (Pacemaker/Corosync or equivalent).

Manage backup and recovery activities for Linux systems, including backup job monitoring, restore validation, and DR drills.

Automate routine administrative tasks using Shell/Bash and Python scripting, and configuration management tools (Ansible/Puppet/Chef).

Hypervisor & Virtualization Support (Secondary Skill)

Provide L2-level support for Linux virtual machines hosted on VMware vSphere/ESXi or Nutanix AHV/Prism environments, including basic VM lifecycle operations (provisioning, cloning, snapshots, resizing).

Coordinate with the Hypervisor/Virtualization team on host-level issues affecting Linux VMs — resource contention, storage/datastore connectivity, and VM performance degradation.

Support basic troubleshooting of VM-level issues — boot failures, guest tools/VM tools issues, and resource allocation problems — for Linux guest OS instances.

Assist with capacity and performance monitoring of Linux VMs within the virtualization platform (vROps, Nutanix Prism monitoring, or equivalent).

Troubleshooting

Diagnose and resolve Linux OS-level issues — boot failures, kernel panics, service crashes, driver conflicts, disk/memory pressure, and performance degradation.

Troubleshoot networking issues on Linux systems — interface configuration, routing, firewall (iptables/firewalld), and DNS resolution problems.

Investigate storage-related issues — filesystem corruption, LVM errors, disk space exhaustion, and mount point failures.

Troubleshoot authentication and access issues — LDAP/AD integration (SSSD/Winbind), sudo/permission errors, and SSH key-based access problems.

Perform root cause analysis for recurring incidents and drive permanent fixes in coordination with L3/Architecture teams.

Security & Access

Implement and manage role-based access control (RBAC), sudo policies, and least-privilege access principles across Linux systems.

Support hardening Linux servers as per organizational security baselines and CIS benchmarks.

Manage SSH key management, certificates, and integration with enterprise secret/credential stores.

Ensure compliance with patch SLAs, vulnerability remediation timelines, and audit requirements.

Platform & Automation

Contribute to platform standardization — golden image/template creation, baseline configuration, and build documentation for Linux servers.

Work with monitoring and observability tools (Nagios, Zabbix, Grafana, or similar) to proactively identify performance and capacity issues.

Support Infrastructure as Code practices for provisioning and managing Linux servers where applicable (Terraform, Ansible).

Document runbooks, SOPs, architecture diagrams, and knowledge base articles for recurring issues.

Participate in on-call rotation and support during planned maintenance/outages.

Required Skills & Qualifications

Bachelor's degree in computer science, IT, or related field (or equivalent experience).

4 to 8 years of hands-on experience in Linux server administration (RHEL/CentOS/Ubuntu/SUSE) as the primary skill set.

Strong command over Linux system administration — user/file/storage management, service management, patching, and shell scripting.

Working knowledge of virtualization/hypervisor platforms (VMware vSphere/ESXi or Nutanix AHV/Prism) is sufficient to support Linux VMs and coordinate with the virtualization team.

Deep troubleshooting experience across Linux OS, storage, networking, and authentication/access issues.

Working knowledge of backup and DR tools/processes for Linux-based workloads.

Preferred / Good to Have

Red Hat Certified Engineer (RHCE) or equivalent Linux certification.
