You have built event-driven applications using Kafka and solutions with event-streaming frameworks at scale (Flink / Kafka Streams / Spark) that go beyond basic ETL pipelines

You know how to orchestrate the deployment of applications on Kubernetes, including defining services, deployments, stateful sets etc. and where to look if there is a problem

You know how to design systems from a macro-level through to the micro-level optimisations needed to build high-performance, scalable solutions

You have tackled hard problems in the past around data consistency vs availability and have designed systems around these considerations

You have designed complex data models and managed their evolution to limit breaking-changes and support backwards compatibility

You have a focus on delivery and an awareness of how your contribution in a software team delivers end-value in a product

You have likely tuned garbage collection, fixed CPU hotspots and analysed heap dumps to find memory leaks on JVMs
