## About the Role

* Seeking an L2 Support Engineer with 5+ years in production support for enterprise applications.
 * Role requires strong Unix/Linux troubleshooting, hands-on database support, and practical Java knowledge for log/code-level analysis.
 * Focus is on incident resolution, root-cause analysis, service stability, and operational excellence.

Must-Have Skills

 * 5+ years in L2/production support for critical applications.
 * Strong Unix/Linux command-line and shell scripting (bash/ksh).
 * Strong database knowledge (Oracle/SQL Server/PostgreSQL/MySQL) with advanced SQL troubleshooting.
 * Working knowledge of Java applications (logs, thread dumps, heap/GC basics, exception tracing).

## Description

* Monitor applications and proactively detect production issues via alerts, logs, and dashboards.

 * Investigate database issues (SQL performance, locks, deadlocks, query failures, data mismatches, job failures).
 * Analyze Java stack traces, GC/log patterns, and service behavior to isolate defects and escalate with clear evidence.
 * Support release validations, post-deployment checks, and rollback coordination where required.
 * Own problem records and drive RCA with corrective/preventive actions.
 * Collaborate with L1, L3/dev, infra, DBAs, and middleware teams for permanent fixes.
 * Maintain runbooks, SOPs, knowledge articles, and incident timelines.
