Technical Skills:
Data Modelling & SQL
Strong data modelling skills — dimensional modelling, star/snowflake schemas, slowly changing dimensions, and the ability to design models that balance analytical performance with maintainability.
Deep SQL expertise — complex queries, window functions, CTEs, recursive queries, query plan analysis, and performance tuning on large datasets.
Good understanding of data formats (Parquet, Avro, JSON, CSV), serialisation trade-offs, and working with structured and semi-structured data.
Modern Data Stack
Hands-on experience with dbt — modelling, transformations, tests, documentation, macros, and incremental models.
Experience with a cloud data warehouse — BigQuery preferred, or Snowflake/Redshift with willingness to work on BigQuery.
Experience building data pipelines using Python and a workflow orchestration tool such as Apache Airflow or Cloud Composer.
Solid understanding of ELT/ETL design patterns — full vs. incremental loads, idempotent pipelines, backfill strategies, and dependency management.
Data Engineering Fundamentals
Good understanding of data lake and data warehouse architectures, and lakehouse concepts.
Experience with data reconciliation — building validation frameworks that compare data across sources and flag discrepancies.
