From the very beginning, OfferUp has believed that the right people united by the right mission can redefine the possible.

OfferUp is now the largest mobile marketplace for local buyers and sellers in the US. We connect millions of people every day, but we’re still as committed as ever to the founding mission: to build the simplest, most trustworthy local marketplace. We help bring people together in their communities to exchange value, and we think that exchange is the foundation for a kind of commerce that redefines what “value” really means. In our world, the things we buy and sell are just the primer for the really important stuff, like meeting our neighbors, getting more connected to the places we live and the things that live with us, and creating a marketplace where everyone has something to offer.

OfferUp is changing how people buy and sell locally by making it as easy as taking and sharing a photo from your phone. We are not just about connecting buyers and sellers; we are about creating a simple and safe marketplace that changes people’s lives. We are a rapidly growing team in Seattle looking to bring on more passionate, motivated, and curious individuals who want to be a part of our fast growing team.

The Promoted Products team has a charter to build tools such as analytics and advertising to help all sellers become more successful in the OfferUp marketplace. Our team takes pride in designing simple tools that can help even inexperienced sellers operate like professionals. Revenue from our products consistently ranks us amongst the top revenue grossing apps on the Google Play and App stores. We recently launched a successful paid subscription for our app, and you will be working on the next iteration of it.
