On-site role: We expect candidates to work from office 4 days a week.

• Set up and configure Amazon Kinesis Data Streams / Firehoses

• Design and implement Apache Flink jobs for real-time data processing

• Optimize performance, scaling, and fault tolerance of streaming pipelines

• Integrate with downstream AWS services
