- Optimize Flink parallelism, task slots, state backends, serialization, memory management, and back-pressure handling for high throughput and low latency.
- Operate fault-tolerant distributed Flink workloads, including task failure handling, job restarts, state recovery, and zero-data-loss deployments.
- Support job observability through logs, metrics, dashboards, and monitoring of health, throughput, lag, checkpoint performance, and failures.
- Deliver software through Agile/Scrum practices and collaborate with engineering, DevOps, security, architecture, and other cross-functional teams.
