    environments.
  • Work with modern file formats (

    DBT
    for data transformation and modeling.
  • Develop best practices and internal standards for data engineering, monitoring, and testing.

    of hands-on experience as a Data Engineer or similar role.
  • Strong proficiency in
    Python

  • Solid understanding of data lake and table formats like
    Iceberg
    ,
    Parquet
    ,
    Delta Lake
    , and their use cases.
  • Familiarity with
    big data processing
    (e.g.,
    Apache Spark
    ) and
    query engines
    (e.g.,
    Trino
    ).
  • Experience working in
    AWS
    environments, and comfort with hybrid
    cloud/on-premise
    infrastructure.
  • Proven ability to work independently, drive decisions, and evaluate technologies with minimal oversight.

Nice to Have

    DBT
    or other data modeling and transformation tools.
