The Search Engine Optimization (SEO) and Landing Page teams define and build features that optimize the way customers browse our inventory and help them easily find and reach relevant eBay pages when searching on search engines like Google, Bing, Yahoo, etc. With literally hundreds of millions of products listed on eBay globally at any time, the scale at which eBay has to consider search engine optimization puts our team in a unique position to innovate and provide immediate value to the business.

The SEO Landing Page Platform holds the buyer intent data definition for our category and model landing pages. These pages serve as important destinations for buyers who come from search engines like Google as well as those who are browsing the eBay site. The Linking Services connect those pages and enable them to show up in navigational elements like the breadcrumb and category navigation. The operational tools provide the interface for manual intervention and eventual automation of those operational tasks. 

​We are looking for seasoned Applied Researchers to join us and help lead improvements, automation, and scaling of our data-heavy processes. Our Senior Researchers tackle such diverse and challenging projects on Image Quality scoring; Automatic Taxonomy Improvement; Entity Resolution of rich, hierarchical Entities; and Conflict Resolution between different representations of the same Entity. Further, they help us design these separate projects and envision how they come together to create and power new experiences that surprise and delight our Customers. If you love a good challenge, and are good at handling complexity - we'd love to hear from you
