  • Rapidly develop a deep understanding of the quantitative methodologies and implementation details behind existing machine learning algorithms in place, and the currently-planned roadmap of enhancements.
  • Formulate business needs as data science problems where applicable and effectively communicate these to peers, managers, and key stakeholders, including the benefits and limitations of models.
  • Design and develop Machine Learning models and algorithms that drive performance and provide insights, from prototyping to production deployment, across key areas of interest to the company (e.g., bidding optimization, messaging optimization, multi-touch attribution, fraud detection, device identification, cross-device association)
  • Partner closely with Engineering on the architecture and implementation of modeling efforts to ensure performance and scalability
  • Partner closely with Product on the incorporation of new modeling features into our product set, including UI & API layers
  • Develop tools and processes to monitor performance of existing models and implement enhancements to improve scalability, reliability, and performance.
  • Create supporting documentation for algorithms and models.
  • Stay abreast of new developments in Machine Learning and Data Science, and investigate & develop new “challenger” approaches to compete against current “champions”
  • Communicate effectively with other Data Scientists, with Product/Engineering, and with business stakeholders across the company to identify and define strategic data-intensive projects based on business needs.
  • Take ownership of significant large projects, develop an overall architecture and roadmap, and supervise junior Data Scientists or Engineers.

  • BS, Masters, or PhD degree in a quantitative discipline (e.g., Computer Science, Math, Physics, Statistics, Electrical Engineering, or similar)
  • Strong quantitative skills, with solid grasp of key concepts in Probability, Statistics, Algorithm design, and Machine Learning.
  • Strong communication skills, and the ability to effectively discuss models with other data-scientists as well as business partners at the appropriate level of technical detail.
  • 3+ years of hands-on experience developing software, with at least a year in Scala and/or Python.
  • 3+ years of hands-on experience with machine learning, predictive modeling, and statistical analysis techniques in a business environment.
  • Passion for hands-on “in-the-trenches” work with real-world data-sets.
  • Desirable: Experience with Machine-Learning/Big-Data Platforms and modeling frameworks, especially Spark and Hadoop.
  • Desirable: Experience with Statistical modeling and Visualization with R or Python


  • Fast learner
  • Analytic thinker
  • Creative problem solver
  • Passion for applying quantitative methods to rea-world problems
  • Highly motivated
  • Collaborative team player
  • Focus on impact and scalability
  • Direct, honest communication style
