Responsibilities

• Develop entity resolution that links inconsistent listing text and images to canonical items.
• Create valuation logic that estimates prices from comparable sales, accounting for recency, condition, and the number of comps.
• Build production monitoring to identify data drift, fraud, stale comparisons, and other quality issues.
• Partner with computer vision teammates to define item matching across sources with varying levels of detail.
• Evaluate build-versus-buy options for data sources, licensing, and third-party pricing feeds.
