- Implement data transformation logic using modern tooling (e.g. dbt, Spark, SQL-based frameworks), ensuring consistency and testability.
- Build and optimise streaming data pipelines (Kafka/Flink or equivalent) to enable near real-time data availability.
- Ensure data quality and reliability through validation frameworks, observability, and robust handling of late-arriving or inconsistent data.
- Design data contracts and schemas that enable reliable integration between upstream event producers and downstream consumers.
- Optimise pipelines and storage for performance and cost efficiency within AWS.
- Collaborate with analytics, data science, and machine learning teams to translate business requirements into high-quality data assets.
- Contribute to data governance practices, including metadata management, lineage, and discoverability.
- 5+ years experience in data engineering, building and maintaining scalable data platforms (required)
