Chartboost is the leading in-app monetization and programmatic advertising platform. We reach a mobile audience of over 900 million monthly unique users globally and process over 200 billion ad requests. The Chartboost SDK is the highest-integrated independent mobile ad SDK and through the Chartboost Exchange, Ad Network, DSP and other services, we empower mobile app developers to build businesses, while connecting advertisers to highly engaged audiences.

Now we’re looking for an exceptional Data Scientist to join a new team focused on the development of our real-time bidder, one of the most exciting and important products within Chartboost. The system powering this product must deal with 100,000’s of requests per second and presents unique engineering challenges.

  • 3 to 5 years of practical experience in a Data Science or Machine Learning role

  • You have a sound understanding of Data Science and Machine Learning principles
  • Strong experience in improving performance of queries and data jobs and scaling the system for exponential growth in data

Bonus points:

  • Knowledge of distributed tools and frameworks, like Spark/Hadoop for quick train/deploy cycles
