  • Team Collaboration: coordinate with developers, testers, and stakeholders to resolve technical issues; participate actively in agile ceremonies and Program Increment planning events.
  • Production Operations Support: work as part of a team to support production operations across a large data pipeline portfolio, including (but not limited to) participating in a team on-call rotation for troubleshooting production issues and outages, defining and integrating performance and reliability requirements into ETL designs, shared code libraries, and enterprise ETL standards.

  • Experience optimizing queries and storage across S3-based data lakes (Iceberg/Parquet), query engines (Athena or Trino), and relational databases (PostgreSQL, Redshift, or Oracle).
  • Foundational proficiency in Python and SQL.
  • Experience with load/performance testing and production troubleshooting of automated data pipelines at scale.
  • Strong analytical, root-cause analysis, and communication skills.
  • Ability to obtain and maintain a Moderate Risk Public Trust clearance; residing in the United States.
