Founding Data Engineer, Pricing and Comps

### **About the Role** As the founding data engineer on a marketplace team, you will build the data pipelines and pricing systems that turn inconsistent sold-listing data into reliable comparable sales and estimates. Your work will help ensure users and stakeholders can understand both the price and its confidence. ### **What You'll Do** * Build and own scheduled ingestion pipelines for sold-listing data from multiple marketplaces and external sources. * Design entity resolution systems that match inconsistent listing text and images to canonical items. * Develop valuation logic that weighs comparable sales by recency, condition, and the number of available comps. * Monitor data quality to identify drift, fraud, stale comps, and other integrity issues before they affect users. * Partner with computer vision colleagues to define item matching across sources with differing levels of detail. * Make build-versus-buy decisions about data sources, licensing, and third-party pricing feeds. ### **What We're Looking For** * At least 5 years of data engineering experience, including building and owning large-scale production ETL and data pipelines. * Experience working with messy, adversarial data in marketplace, pricing, fraud, or similarly noisy domains. * Strong SQL skills and experience with modern data tools such as dbt, Airflow or Dagster, and Spark or similar technologies. * Experience with statistical estimation or pricing models, including basic regression-based comparable-sales logic. * Experience designing entity resolution or record-linkage systems at scale, and production monitoring for data quality, drift, or anomalies. * Experience processing data from multiple external sources, making technical build-versus-buy decisions, and communicating pricing confidence and uncertainty to non-technical stakeholders. * Pricing intelligence, third-party data licensing, or early-stage startup experience is a plus. ### **Compensation & Benefits** Annual base salary: $160,000 to $220,000. Visa sponsorship is not available. ### **Location** Hybrid, New York, New York, United States.
