Founding Data Engineer (Pricing/Comps)
About the Role
Build and own the data foundation behind pricing for an online resale marketplace. You will turn noisy, inconsistent sold-listing data into trustworthy comparable sales and price estimates, partnering closely with the computer vision team to define how items are matched across sources.
What You'll Do
Build and operate scheduled ingestion pipelines for sold-listing data from multiple marketplaces and sources.
Develop entity resolution systems that match inconsistent listing text and images to canonical items.
Create valuation logic that weighs factors such as recency, condition, and the number of comparable sales.
Monitor data quality and identify drift, suspected fraud, and stale comparable listings before they affect users.
Work with the computer vision lead to determine what qualifies as the same item across data sources.
Evaluate data sources, licensing options, and third-party pricing feeds, making practical build-versus-buy recommendations.
What We're Looking For
At least 5 years of data engineering experience, including building and owning production ETL pipelines at scale
