Founding Data Engineer, Pricing and Comps

Responsibilities

• 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 weights comparable listings by recency, condition, and quantity.
• Create production monitoring to detect data drift, fraud, stale comparisons, and integrity issues.
• Partner with computer vision teammates to define how items are matched across sources with varying detail.
• Make build-versus-buy decisions about data sources, licensing, and third-party pricing feeds.
• Build the data foundation for pricing in an early-stage internet marketplace. You will turn noisy sold-listing data into reliable comparable items and price estimates, helping users and investors understand both the value and confidence of each estimate.
