System Admin - Linux Storage

We are seeking a skilled Systems Engineer Linux & Storage to join our team. The role owns Linux infrastructure and enterprise storage environments end-to-end from proactive monitoring and automation through root cause analysis and continuous improvement ensuring high availability, performance, and reliability of client systems. This is an operational engineering role, not a pure support function: the engineer is expected to reduce recurring issues through automation, drive standardization, and continuously improve operational practices.

Primary skills-

Linux Administration (RHEL/CentOS/Ubuntu), Shell/Bash & Ansible Automation, SAN/NAS Storage, Backup & Recovery, Patching & Security Hardening, Shift Leadership

Responsibilities-

Linux Administration

• Administer, monitor, and troubleshoot enterprise Linux environments (RHEL, CentOS, Oracle Linux, Ubuntu).
• Perform OS installation, configuration, patching, upgrades, and hardening activities.
• Manage user accounts, permissions, file systems, services, kernel parameters, and performance tuning.
• Troubleshoot system issues related to CPU, memory, storage, networking, and application performance.
• Troubleshoot cross-domain issues spanning Linux, storage, virtualization, network, and application dependencies to isolate true root cause.
• Manage packages and repositories using patch/repository management tooling (e.g., Satellite, Spacewalk, YUM/DNF/APT repos).
• Use Git/version control for scripts, automation content, and configuration management.

Automation & Scripting

• Drive automation as a core responsibility, not an optional add-on with strong hands-on Shell/Bash scripting and Ansible for configuration management, patching, and repetitive operational tasks.
• Build and maintain Ansible playbooks/roles for provisioning, patching, hardening, and routine operational workflows.
• Python scripting is a desirable addition for extending automation and tooling capabilities.
• Apply an automation/AI mindset proactively using modern AI-assisted tools for scripting, troubleshooting, log analysis, and documentation to improve speed and quality of resolution.
• Identify recurring issues and build automated, permanent fixes to reduce repeat incidents and manual effort.

Storage Administration

• Manage and support enterprise SAN/NAS storage platforms with meaningful, hands-on experience deep expertise across every storage vendor/product is not required.
• Provision storage, create and manage LUNs, storage pools, RAID groups, volumes, and snapshots.
• Monitor storage capacity, utilization, performance, and availability.
• Troubleshoot storage connectivity issues involving Fibre Channel (FC), iSCSI, multipathing, and zoning.
• Support storage migrations and expansion activities.

Backup & Recovery

• Administer enterprise backup solutions such as Veritas NetBackup, Commvault, Veeam, or similar, with practical hands-on experience on at least one major platform.
• Perform backup monitoring, restoration requests, disaster recovery validations, and troubleshooting.
• Ensure compliance with backup policies and recovery objectives.

Security, Patching & Compliance

• Own the end-to-end patching lifecycle planning, testing, scheduling, and execution – across Linux estates.
• Drive vulnerability remediation in coordination with security teams, tracking findings through to closure within SLA.
• Implement and maintain security hardening baselines and compliance standards (e.g., CIS benchmarks) across Linux systems.
• Support audit and compliance reporting for patch and vulnerability status.

Operational Engineering & Continuous Improvement

• Proactively monitor systems and storage to identify risks and degradation before they cause incidents.
• Lead root cause analysis (RCA) for critical incidents and drive permanent, automated fixes rather than workarounds.
• Track and reduce recurring issues through problem management and process improvement.
• Continuously improve monitoring, automation, and operational runbooks to raise efficiency and reliability.

Incident & Operations Support

• Act as Shift Lead for Linux/Storage operations and support teams.
• Lead complex incident triage, root cause analysis, and resolution activities.
• Coordinate with cross-functional teams, vendors, and customers during major incidents.
• Participate in on-call support and rotational shift schedules.
• Prepare incident reports, technical documentation, SOPs, and knowledge articles.
