Software Engineer II - Seller Experience

About the Team
The Seller Experience team builds products that give sellers confidence at every step of their journey. We want sellers to understand where things stand, know what to expect, and feel supported when something needs attention. For a seller, a great experience means clear information about their sales, payments, and charges, timely updates without having to ask, and straightforward ways to take action. When something goes wrong, filing a dispute should be easy, progress should be visible, and the resolution should be understandable. We bring together experiences across the marketplace to make selling feel connected and intuitive. Our mission is to earn sellers’ trust through transparent information, reliable experiences, and tools that help them stay in control—so they choose to sell with StubHub again.
