Job Description

As a Data Scientist in our Decision Sciences Visualization team, you will create innovative visual analytics systems that reveal, explore and explain complex patterns and phenomena from Epsilon’s peta-scale and massively-dimensional digital marketing ecosystem.  You will reduce this complexity into sophisticated, interactive visual metaphors and stories that demonstrate the business value of Epsilon’s platform directly to our stakeholders and global customers (which includes some of the world’s largest brands). Our visualization challenges span hundreds of millions of highly detailed individual profiles across hundreds of millions of web sites and apps tied together by sophisticated real-time analytics that make near instantaneous decisions on messaging to those profiles trillions of times a day. This provides an incredibly rich environment of business questions and answers that are hidden within petabytes of data. 

In this role, you will be a key member of a multi-disciplinary R&D team creating a full-stack visual analytics system that connects to big data platforms and machine learning systems to present complex enterprise-critical information in an engaging, intuitive and informative manner. This is a multi-faceted team effort involving an array of technologies such as Python, PySpark, Scala, SQL, Hadoop/HDFS, Elastic Search, GPU clusters, D3.js, Reactjs and more.  We are looking for strong candidates with extensive experience in clustering, dimensionality reduction and machine learning (particularly unsupervised techniques) on large scale computing clusters, and who are driven by the desire to see those results translated into actionable insights.

  • Participate fully in our collaborative approach to research and applications projects
  • Be a supportive and positive contributor in a highly collaborative, multi-disciplinary R&D team with shared and overlapping responsibilities, all in support of a strong mission with purpose and proven results
