The Data Science Engineering (DSE) team is responsible for the economics of NextRoll’s core products. Our in-house machine learning frameworks run over hundreds of terabytes of data daily, ensuring our pricing engine stays fresh and accurate as it bids on billions of ad opportunities, dynamically making product recommendations, and selecting the best opportunities for our advertisers. Machine Learning (ML) engineers have a passion for technology and mathematics, and are responsible for setting up the systems architectures that feed and execute our machine learning algorithms at scale.

NextRoll engineers are afforded significant autonomy. The ML engineers design their systems as they see fit, own their code, enable analysts to dive deep with ease, and ensure our hungry machine learning algorithms are fed. Our ML engineers work on a variety of projects with data from disparate sources, but all at a large scale. Our systems are built on top of Amazon’s AWS and employ cutting edge technologies.
