💻 Role

Ads is a growing engineering team at Whatnot that is dedicated to building systems & features to help Sellers grow their business. As a software engineer on the Ads team, the most important qualities you'll need are making sound product decisions, navigating new domains seamlessly, taking extreme ownership, and shipping high-quality products fast.
