  • Drive adoption & utilization of your products across the organization in ways that drive real business value
  • Architect and help define the required technical platforms that enable us to produce models at scale 


What You'll Need

  • 2+ years of experience in a quantitative or technical work environment, or an advanced degree (PhD) in quantitative field (e.g. mathematics, economics, computer science, statistics, engineering, physics, neuroscience, operations research etc.)

  • Ability to thrive in a dynamic environment where Data Science plays a key role in shaping business & technical priorities
  • Machine Learning experience in a professional or advanced academic setting (e.g., supervised/unsupervised learning, recommendation systems, reinforcement learning, deep learning, etc.)
  • High comfort level with Python (preferred), or with other programming languages. Experience with big data tools such as Hadoop, Spark, Presto, etc.
  • Prior experience building scalable data processing pipelines with big data tools such as BigQuery, Spark, etc. Experience with Airflow and containerization (Docker) are nice to have
