Senior Data Science Engineer

AdRoll is a leading performance marketing platform with over 35,000 clients worldwide. Its suite of high-performance tools works across devices, helping businesses attract, convert, and grow their customer base. The company is home to the world's largest opt-in advertiser data co-op, the IntentMap™ with over 1.2 billion digital profiles. AdRoll’s goal is to build the most powerful marketing platform through performance, usability, and openness.

The Data Science Engineering team writes the math and software that sit at the heart of AdRoll’s real-time bidding technology, our core product. Our software runs over hundreds of terabytes of data daily to produce its models, which are then subsequently queried billions of times by hundreds of servers. Current members of Data Science Engineering have a passion for not only mathematics, but also technology. You will have the opportunity to stay on the cutting edge of research and then to put this research to practical use by building your own software and infrastructure systems. When you push out your code, you will be able to see the results of your efforts ripple throughout our systems in real-time. Your interests dictate what projects you will tackle. The common thread among all projects is that they require a high level of mathematical sophistication and engineering prowess, due to the scale of our data.
