Company Details

Role Summary

The Tier-2 NOC Engineer takes escalations from Tier-1 and restores service across our customer contracts, which span on-premises, Microsoft Azure and AWS environments, each with its own SLA. You will troubleshoot across network, compute, operating system, database, application and cloud layers, engage vendors and internal teams, and keep customers informed during major incidents.

You will also make the NOC better over time: tuning noisy alerts, writing and automating runbooks, and raising problem records so recurring issues are fixed for good. You will work closely with the SOC, providing infrastructure data during security investigations.

Job Details

Key Responsibilities

• Diagnose and Restore
• Take escalated tickets from Tier-1 and troubleshoot across network, compute, OS, database, application and cloud layers.
• Restore service through fixes, failover, scaling, or rolling back a bad change, within contract SLAs.
• Identify the likely root cause and record it, with resolution notes, in the ticket.

Change Management

• Raise and implement emergency changes needed to restore service.
• Roll back changes that cause incidents, and check whether a recent change caused an incident.
• Execute critical out-of-band patches when requested by the SOC and validate service health after patching.
• Coordination and Communication
• Engage vendors (Oracle, Microsoft, AWS, ISPs and others) and internal infrastructure and application teams.
• Send status updates to customers and stakeholders on each contract's schedule during P1/P2 incidents.
• Collect and provide data (logs, configurations, flow data) to the SOC on request during security investigations.

Continuous Improvement

• Raise problem records for recurring or unexplained issues.
• Tune alerts: remove noisy ones, adjust thresholds, and action false-positive tuning requests from Tier-1.
• Write and improve runbooks and automate common fixes so Tier-1 can resolve more issues at first contact.
• Coach Tier-1 analysts on troubleshooting and runbook use.
