  • Experience working with event‑streaming or messaging platforms (e.g. Kafka or equivalent), including concepts such as topics, partitions, schemas, consumer groups, and delivery semantics.
  • Experience modelling data in NoSQL technologies (e.g. MongoDB) within distributed, eventually consistent systems.
  • Experience deploying and running services on cloud platforms (such as AWS), with awareness of security, networking, and cost considerations.
