- Design and optimize relational and NoSQL data models, queries, indexes, and database access patterns.
- Apply appropriate software design patterns, clean-code principles, and engineering best practices.
- Improve application performance, scalability, reliability, resilience, and security.
- Implement appropriate retry, timeout, circuit-breaker, idempotency, and error-handling patterns for distributed systems.
- Develop automated unit, integration, API, and component tests to maintain software quality.
- Participate in technical design and architecture reviews and contribute to engineering standards and reusable solutions.
- Perform peer code reviews and mentor junior and mid-level engineers.

L2 Application & Production Support :

- Provide Level 2 technical support for production applications and services, acting as an escalation point for incidents that cannot be resolved by L1/Operations teams.
- Investigate and resolve application, API, microservice, database, messaging, integration,



infrastructure, and configuration-related production issues.
- Perform technical troubleshooting using application logs, distributed traces, metrics, database queries, AWS CloudWatch, dashboards, and other observability tools.
- Diagnose issues across distributed systems, including API failures, timeouts, performance degradation, database connectivity, message-processing failures, and upstream/downstream integration problems.
- Assess incident severity and business impact and prioritize troubleshooting and recovery accordingly.
- Restore services within agreed SLA/SLO and operational targets and provide timely technical updates during incidents.
- Participate in major incident management and collaborate with L1, L3/development, DevOps/SRE, infrastructure, database, network, security, and external/vendor teams where required.
- Perform Root Cause Analysis (RCA) for recurring or high-severity incidents and identify corrective and preventive actions.
- Implement permanent fixes to eliminate recurring incidents rather than relying solely on operational workarounds.
- Support incident, problem, and change management processes.




- Perform production health checks and proactively identify abnormal application behavior, resource utilization, error rates, latency, failed transactions, and integration failures.
- Monitor and troubleshoot asynchronous processing, including Kafka topics/consumers, SQS queues, SNS integrations, dead-letter queues, and failed/retried messages.
- Troubleshoot SQL/NoSQL issues including slow queries, connection pool exhaustion, locking, data inconsistencies, replication-related behavior, and database performance.
- Support production releases, hotfixes, rollback activities, and post-deployment validation.
- Create and maintain runbooks, troubleshooting guides, operational procedures, known-error documentation, and knowledge-base articles.
- Improve alerts and dashboards to reduce Mean Time to Detect (MTTD) and Mean Time to Resolve (MTTR).
- Identify opportunities to automate repetitive support and operational activities.
- Participate in an on-call/support rotation where required and provide support for priority incidents outside standard business hours according to the agreed support model.
- Conduct knowledge-transfer sessions with L1/support teams to improve first-line resolution capability and reduce unnecessary escalations.
- Ensure production incidents and fixes comply with organizational security, audit, change-management, and operational requirements.
