- Coordinate with InfoSec, Networking, and Cloud Platform teams on secure network paths (VPC, subnets, security groups, NACLs, private endpoints)
- Build and maintain observability: metrics, logs, traces, dashboards, and alerts for Kafka/MQ/MFT/Cache.
- Handle production incidents, perform root cause analysis (RCA), implement corrective/preventative actions, and drive service improvements.
- Tune MQ/Kafka performance (batching, compression, partition strategy, consumer lag management) and Elasticache parameters.
