Pinterest is looking for a Senior Staff Software Engineer to lead Performance Ads Formats, a team building ad products and experiences that help Pinners turn intent into action and help lower-funnel advertisers drive stronger outcomes. In this role, you’ll be a senior technical leader across a suite of products such as Deal Ads, dynamic ad experiences, post ad click journeys, and more.
