  • Build and maintain Amazon Kinesis Data Streams infrastructure including shard management, auto-scaling policies, and dead-letter queues.
  • Implement comprehensive observability: CloudWatch/Grafana dashboards, distributed tracing, structured logging, and tiered alerting (P1/P2/P3) across the full pipeline.
  • Troubleshoot and resolve production issues across the ingestion-to-serving stack (Kinesis, Flink, DynamoDB, S3, Athena)
  • Develop and maintain Infrastructure-as-Code (CDK/CloudFormation) for all pipeline components, ensuring repeatable and auditable deployments.

  • Experience with AWS services: DynamoDB, S3, Athena, CloudWatch, IAM.
  • Proficiency with Infrastructure-as-Code (CDK, CloudFormation, or Terraform).

Preferred:

  • Experience with MQTT, Haystack protocol, or Niagara N4 (building automation / IoT).
