About the team and the role:

Welcome to the Product Knowledge organization at eBay, where we sit at the intersection of AI, data science, and seller empowerment. Our team is the core architect behind the structured data, taxonomies, and intelligent tools that power global commerce for millions of users. We operate with a high-agency, startup-like, and high-trust culture that values bold ideas, authenticity, and a healthy work-life balance. As the Data Science Manager for Knowledge Management, you will lead high-visibility analytical initiatives to shape how products are priced, cataloged, and listed. Depending on your team placement, you will develop deep insights and assess models. You will create proof-of-concept (PoC) solutions for critical areas including AI-based Price Mentorship and image-to-text Magical Experiences. These solutions greatly reduce listing times for sellers. Reporting within our Product Knowledge division, you will bridge the gap between advanced models (LLMs/VLMs) and scalable seller workflows.

What you will accomplish:

- Drive Core Seller Initiatives: Deliver deep analytical insights and create proof-of-concept (PoC) models throughout the product lifecycle to back features like Machine Learning based Price Guidance and AI listing tooling.

- Evaluate Sophisticated GenAI Workflows: Design robust benchmarking and evaluation frameworks to measure the accuracy and performance of Large Language Models (LLMs)

- Power "Magical" Listing Experiences: Optimize innovative VLM workflows that extract structured catalog attributes directly from seller images, significantly reducing friction and time-to-list.

- Shape Taxonomy & Discovery Strategy: Conduct deep data dives using SQL and Python to refine eBay's search algorithms, catalog infrastructure, and global ontologies for a highly intuitive browsing experience.
