• Define SLIs, SLOs, and reliability standards for critical streaming services
• Build monitoring and alerting using Prometheus
• Investigate latency, throughput, consumer lag, backpressure, and processing failures
• Automate infrastructure provisioning and configuration using Terraform
• Improve partitioning, scaling, and resource-allocation strategies
• Build reliability tooling in Java and/or Scala
• Automate recovery and reduce manual intervention during incidents
• Perform capacity planning for growing event volumes
• Partner with Data and Platform Engineers to design more resilient streaming systems
