Senior ETL Developer


How does building an entirely cloud based, open source data warehouse sound to you? As ETL developer this is exactly what you will be doing.

As the world’s largest HR service provider, the amount of information that passes through our systems every day is vast. Using accurate data to inform our decision making processes and to guide us is therefore an integral part of our strategy. Our Data Insights team are helping us build an entirely new environment between our AWS datalake and Tableau reporting, drastically reducing the number of reports we need.

Where our datahub team connects all of our various data sources, our data insights team focuses on the transformation aspect of the ETL proces, integrating data sources into a multi-dimensional data model we can use to build analyses across a multitude of sources.

In doing so, we are saying goodbye to our existing Redshift Data Warehouse and focusing on a new greenfield build based on the DBT open source data transformation tool, Airflow scheduling and Snowflake.
