What is a UX/UI Designer at Poshmark?

As a UX/UI Designer at Poshmark, you are at the intersection of social media and e-commerce. You aren't just designing a storefront; you are building a vibrant community where millions of users buy, sell, and connect. Your work directly impacts how people discover fashion, manage their own small businesses, and engage with a marketplace that thrives on social interaction rather than just transactions.

The role requires a balance of high-level product strategy and meticulous execution. You will be responsible for creating seamless end-to-end experiences across mobile and web platforms, ensuring that the Poshmark "social commerce" mission is reflected in every interaction. Whether you are optimizing the listing flow for sellers or enhancing the discovery experience for buyers, your designs must scale to support a massive, diverse global audience.

Success in this position means moving beyond aesthetics to solve complex marketplace problems. You will work on features that involve high levels of user trust, community moderation, and real-time social engagement. It is a role that demands deep empathy for the "Poshmark community" and a data-driven approach to iterative design.

Common Interview Questions

Getting Ready for Your Interviews

The interview process at Poshmark is designed to be comprehensive and collaborative, offering you a clear view of the team culture and the types of challenges you will solve.
