WHAT WE’D LOVE YOU TO DO (AND LOVE DOING)
Build and own personalization systems: develop recommendation models (content-based, collaborative filtering, ranking) that directly shape what customers see in emails and push notifications
Drive predictive modeling; lead CLV prediction, churn and other propensity models that turn complex data into actionable strategies for our Marketing teams
Design rigorous experiments: own A/B tests and incrementality experiments to measure the true causal impact of CRM campaigns and personalization initiatives on revenue and long-term customer value
Integrate science into production: partner with Engineering to bring models into production, defining feature stores, data pipelines and monitoring frameworks
Bridge science and business: translate model results and their limitations into clear, structured insights that influence campaign and personalization roadmaps
Elevate the team: actively participate in code reviews, share ideas in a culture of open collaboration, mentor peers and be mentored in return
