Job description

Address: TCS GG7 office is located at Skyview Corporate Park, Sector 74A, Gurugram, Haryana, 122004

Experience: 6 years to 13 years

Interview Mode: Walk In Drive

Interview Date: 8th Aug 2025 (Saturday)

Interview Time: 10: 00 AM to 1: 00 PM

Mandatory skill set:

• OS Currency, EOL Remediation & Patch Execution
• Monitoring/Event Mgmt Tooling (ServiceNow ITOM, SolarWinds, Grafana)
• Cloud Operations (AWS/Azure Linux) & Automation Exposure (SSM/Ansible)
• DR Support, Documentation, Risk & Capacity Inputs
• Linux Tower Architecture & Standardization (Target baselines), EOL Burn-down Strategy + Patch Governance/Automation (SSM direction), Observability/Event Mgmt Integration (ITOM/SolarWinds/Grafana)

Certification:

• RHCSA/RHCE or equivalent Linux administration credential; ITIL Foundation/ ITIL 4 Managing Professional.

Must-Have:

• Provide L2/L3 operations for customer’s UNIX/Linux estate across on‑prem + AWS + Azure + VMware, with strong focus on OS currency (EOL remediation), patch compliance, monitoring/event management integration, and operational stability
• Ownership of end-to-end Linux tower delivery service and transformation — driving Linux standardization, EOL burn-down strategy, patch automation adoption, DR readiness governance alignment, observability maturity, and SLA-led operations, emphasizing event management, patching automation, risk registry, and operating model maturity.

Tools / Platforms

• ITSM / Event Mgmt / AIOps: ServiceNow, ServiceNow ITOM
• Observability / Logs: Grafana (Prometheus stack), Loki/Fluentd
• Patching: AWS SSM direction for patching onprem + cloud; SCCM/Intune
• Automation/Orchestration: ServiceNow + AWX/Ansible + Terraform
• Batch: Control‑M / Tidal (where Linux workloads rely on scheduling dependencies)

Good to have:

• AWS Cloud Practitioner or AWS SysOps (for Linux on AWS); Azure Administrator (for Linux on Azure); ServiceNow fundamentals; Ansible basics.
• AWS Solutions Architect (or SysOps), Azure Solutions Architect, ServiceNow ITOM fundamentals, automation certs (Ansible/Terraform)

Key Responsibilities:

• Provide advanced troubleshooting and resolution for Linux incidents (availability, performance, filesystem, user/access, services, kernel-related issues).
• Support operational activities across on‑prem, AWS, and Azure Linux estates, aligning to the broader customer operating model for infrastructure operations and administration.
• Execute OS version upgrades and remediation for EOL/EOS Linux servers, prioritizing critical systems and high-risk populations (e.g., EOL VMs)
• Maintain compliance with “supported version levels” expectations by ensuring planned upgrades and reducing vendor support risk exposure.
• Perform patch planning/execution and support the customer’s direction to extend AWS SSM for patching across on‑prem and cloud, including pre-check/post-check automation and maintenance coordination.
• Operate within the approved tool landscape for patch/image management (SCCM/Intune) where relevant to server operations and standardization.
• Integrate Linux monitoring into Customer’s ServiceNow ITOM event management approach and downstream monitoring tools like SolarWinds, plus observability via Grafana/Loki where used.
• Improve alert quality by participating in tuning thresholds and reduction of noisy events, consistent with the customer event management direction.
• Support DR readiness activities for Linux workloads, aligning to the TDAF callout that periodic DR testing/governance must be established (execution support, runbook validation, recovery assistance).
• Provide operational inputs into capacity planning and proactive risk identification (CPU/memory/storage growth trends).
• Maintain Linux SOPs/runbooks and update CMDB/service records as required through ServiceNow, aligned to the tool strategy emphasizing ITSM/CMDB integration.
• Define the Linux OS standard/version baselines and a sequenced plan to reduce EOL exposure (including EOL VM populations highlighted in inventory)
• Drive estate rationalization across platforms (VMware/AWS/Azure) and ensure “supported release” posture to reduce operational and security risk.
• Establish patch policy, cadence, and compliance reporting; operationalize customer’s direction to extend AWS SSM patching for on‑prem and cloud, including automation of checks and standardized runbooks.
• Align patch/image practices to Customer’s retained tool ecosystem (SCCM/Intune).
• Ensure Linux signals (metrics/logs/events) are integrated into ServiceNow ITOM event management and correlated with downstream tooling (SolarWinds) and observability dashboards (Grafana/Loki).
• Sponsor alert-quality improvements (threshold strategy, noise reduction)
• Implement Linux tower contribution to DR readiness, aligned to the TDAF callout that DR drills/process governance must be mandated and executed, ensuring Linux workloads meet agreed RTO/RPO expectations by criticality.
• Define Linux tower SLAs/OLAs, measurement methods, and reporting cadence.
• Ensure Linux tower maintains and governs a risk register and operational documentation discipline via ServiceNow/CMDB integration.
• Serve as the Linux tower escalation owner for P1/P2 issues, stakeholder communications, and cross-tower coordination (Compute/Network/DB/Storage).
