This is a rare opportunity to be involved in creating an automated system to optimize hundreds of real-time interactions per second with online customers, and to quantify the benefits created against control groups in a live environment. The work involves analyzing billions of records of ad-serving opportunities, ad-servers, and ad-server responses to understand what factors explain the variance in the expected response value. That understanding is then to be harnessed as an automated optimization process capable of intelligently finding and servicing the most favorable ad-serving opportunities in a way that leads to higher returns on our clients’ advertising investments. Guidance is available from a senior analytical party who will support the work.
