Nielsen is the largest measurement company in the world with unique technologies, assets, and data that make it one of the most interesting and challenging places for a data scientist to work.  We focus on measuring total media consumption across all platforms in over 90 countries and counting.
 
Data Science is core to what Nielsen does and our research projects have high visibility in directly affecting the results of our business and our clients.  The Senior Data Scientist role provides an opportunity to contribute to methodological innovation in the exciting and fast changing world of media measurement.  This is an ideal position to grow as a researcher, contribute to innovative products, and deploy cutting edge methodologies in audience measurement methodology and integrate big data into existing products.
 
About the team
The Cross Media team within the Data Science organization focuses on improving and enhancing Nielsen’s highly successful audience measurement products out in the marketplace for advertising and content measurement. As part of this exciting team, this position will focus on developing new methodologies to measure audiences across platforms (including on “connected” or “over the top” devices, smart tv’s, or set top boxes) and on evaluating and integrating new data assets and partners into Nielsen’s existing methodologies in order to enhance or expand the data delivered to clients.
 
A major focus of this work is total audience representation across demographics.  Advertisers do not just need to count audience members.  They need to know who is watching.  Ensuring all groups are appropriately represented in measurement is core to Nielsen’s value and a key role of this team.
