Key Responsibilities

- Cluster Architecture & Solutioning: Design, architect, and optimize Confluent Kafka clusters stretched across four geographically distributed data centers. Define topic architecture, partitioning strategy, replication factor, and rack-awareness configurations. Provide solutioning inputs, capacity planning, and sizing for current and projected TPS loads. Collaborate with enterprise architects and application teams on event-driven and streaming solutions.

- Deployment & Configuration: Lead end-to-end deployment of Confluent Kafka components (Brokers, Zookeeper/Kraft, Schema Registry, Kafka Connect, ksqlDB, REST Proxy, Control Center, and MirrorMaker/Cluster Linking). Manage cluster upgrades, patching, and version migrations with minimal downtime. Implement security configurations (SSL/TLS, SASL/Kerberos, ACLs, RBAC). Configure and manage multi-DC replication strategies.

- Production Support & Troubleshooting (L3): Act as the highest level of technical escalation (L3) for production incidents, providing RCA and permanent fixes. Monitor and manage a environment supporting ~4.5 crore accounts with a throughput of 5,000–10,000 TPS. Troubleshoot broker failures, ISR issues, consumer lag, partition rebalancing,



and replication issues. Perform deep-dive performance tuning (JVM, OS, network, producer/consumer). Drive proactive capacity planning.
- Monitoring & Operations: Set up and manage monitoring, alerting, and observability using Confluent Control Center, Prometheus, Grafana, and Splunk/ELK. Track operational metrics like broker health, under-replicated partitions, consumer lag, latency, and throughput. Ensure adherence to banking regulatory, audit, and compliance requirements. Participate in DR drills, BCP, and periodic failover testing.
- Ecosystem & Integration Knowledge: Demonstrate strong understanding of the surrounding banking ecosystem (core banking systems, payment gateways/switches, NPCI/RTGS/NEFT/IMPS/UPI rails, fraud engines, reconciliation systems). Partner with cross-functional teams to resolve issues impacting Kafka pipelines. Support integration via Kafka Connect, custom producers/consumers, and stream processing frameworks.
- Documentation & Governance: Create and maintain runbooks, SOPs, architecture diagrams, and knowledge base articles. Enforce platform best practices and governance. Mentor L1/L2 support engineers.
