Senior Modeling Scientist, Prospecting

Quantcast helps create a more personalized digital world. We have built one of the world’s most sophisticated data-intelligence platforms, using big data and machine learning to solve the biggest challenges in marketing and create more rewarding experiences across the digital landscape.

The Prospecting team’s vision is to help our customers better understand their audiences and to deliver relevant advertising across all internet media. The team builds and operates real time prediction and control systems that power all our advertising products at scale. This means getting up-close and personal with cutting edge machine learning techniques and advertising delivery systems. You’ll have the opportunity to leverage Quantcast’s massive computing power to build tens of thousands of predictive models, use these models to make over 2 million advertising decisions per second, and deliver advertising to appropriate audiences 24x7. We are looking for top tier talent to solve day-to-day advertising campaign issues, identify opportunities to improve our machine learning and advertising delivery technologies, and implement those improvements to reach relevant audiences on behalf of our advertisers. We are interested in modeling scientists with a strong production development background as well as a keen interest in data analysis, machine learning and control systems. You will work within a world class modeling group of scientists and engineers that spans multiple product teams and collaborates closely with our scientific advisors, Stanford professors Jerome Friedman and Trevor Hastie. As leaders in the fields of data mining and statistics, both professors take an active interest in Quantcast and our ongoing work.
