Smadex is a leading advertising technology company founded in Barcelona in 2010 and sold to American-based and stock-listed Entravision in 2018 (NYSE::EVC). We power campaigns for Apps, Games and Brands across Mobile and CTV using advanced machine learning and optimized creative strategies to deliver results. Smadex is one of the fastest growing DSPs globally and we are adding talent to fuel our ambitious plans.

We are seeking a highly motivated and well-connected Mobile Publisher Manager to spearhead the growth of our brand-new SDK. In this hybrid role ideally based in one of these cities (Barcelona, Austin, Berlin, Manila, Beijing, or Seoul), you will act as both a relentless business developer and a strategic account manager. You will be responsible for identifying, pitching, and closing top-tier mobile app publishers, while completely owning their end-to-end onboarding and long-term success.

The ideal candidate is an ad-tech veteran currently working at a Supply-Side Platform (SSP) or an SDK-based Ad Network, who brings a robust, active black book of direct mobile publisher relationships. If you thrive in a fast-paced environment and know how to drive SDK adoption from the first pitch to technical integration and scaling, we want you on our team.
