In this role you will develop and implement advanced recommendation and ranking models that power personalized Sportsbook and Casino experiences, and build a deep understanding of customer behavior through the marketing, product, and analytics lens. This role requires a strong background in data science, modern deep learning, and large-scale customer analytics. You will own open-ended, ambiguous problems end-to-end—from ideation and problem formulation, through model research and offline evaluation, to partnering with ML Engineering on production deployment and post-launch iteration.

Define and evolve the technical architecture for modern personalization systems (feature pipelines, candidate generation, ranking, feedback loops), partnering closely with ML Engineers and Data Engineering.
Perform analysis on large and complex data sets utilizing relevant tools (SQL, Python, Spark) and provide strategic contributions
Use statistical and machine learning techniques to segment users and predict future behaviors, developing automated logic and decision algorithms to deliver a better experience to the customer
Lead projects from start to finish, set proper expectations, and collaborate with other data scientists, ML engineers, and product managers to communicate technical findings and support data driven decision making
Oversee the integration and deployment of cross-functional and cross-organizational projects, developing process improvements and technical leadership
Stay up to date on the latest advancements in data science and leverage cutting edge technology
Mentor, brainstorm with, and enable others within the DS team and broader Data organization
