This includes building ETL pipelines between diverse data sources and destinations, architecting new solutions to support production-level APIs, syncing application data into analytics-ready warehouses, and tackling ad hoc data challenges that don't fit neatly into existing patterns. The scope of work varies from standing up repeatable sync jobs to researching and prototyping new approaches for problems the team hasn't solved before. The ideal candidate is someone who thrives in a fast-moving product engineering environment, can navigate ambiguity in requirements, take ownership of problems from investigation through production deployment, and maintain a high standard of documentation and data quality. They should be equally comfortable maintaining established pipelines and independently researching new tools or architectures.
