ABOUT THE ROLE Join an early-stage internet marketplace company to build the data systems behind reliable pricing estimates.

WHAT WE'RE LOOKING FOR - At least 5 years of data engineering experience, including ownership of large-scale production ETL and data pipelines. - Experience working with messy, adversarial data in marketplaces, pricing, fraud, or a similarly noisy domain. - Strong SQL skills and experience with modern data tools such as dbt, Airflow or Dagster, and Spark or similar technologies. - Experience with entity resolution or record linkage at scale, and production data quality monitoring. - Exposure to statistical estimation or pricing models, including regression-based comparable-sales logic. - Experience ingesting data from multiple external sources and making technical build-versus-buy decisions. - Pricing intelligence, data licensing, and early-stage startup experience are helpful.
