As a Lead Data Engineer, you will report to the Head of Data and work closely with other members of the Data team to deploy predictive models as a service, build our data infrastructure, and maintain and improve data pipelines. We believe that data engineers should not write ETL, unless data pipelines are necessary to support the services that we build and maintain. Instead, your time is better spent writing tooling and creating abstractions to support the work of analysts and data scientists on the team, so that other users in the company can write and maintain their own ETL
