• Hands-on experience with real-time data processing frameworks (e.g. Kafka, Flink, Spark Streaming, Pulsar).
• Experience working with cloud platforms (AWS, GCP, or Azure) and containerisation/orchestration (Docker, Kubernetes).
• Strong understanding of data modelling, storage systems, and streaming/processing architectures.
• Familiarity with ML tooling such as MLflow, ZenML, or Metaflow.
• Familiarity with ML model lifecycle management (training, deployment, monitoring).
• Excellent collaboration and communication skills, with the ability to work cross-functionally.

Nice to have
