You will build predictive and causal models on member-leveldata from programs with millions of members, run them reliably in production, and explaintheir impact to client stakeholders. The role is roughly 70% technical (modeling, statistics, engineering of ML systems) and 30% business (framing problems, working with clients, translating results into decisions).You will work closely with Product, Data Engineering, Engineering and Customer Success. What you will OWN Predictive & Statistical Modeling (technical): Design, train and validate models for churn,propensity, next-best-offer, lifetime value, tier migration and anomaly or fraud detection.Choose methods on evidence: regression and GLMs, survival analysis, gradient boosting,probabilistic and Bayesian models, time-series forecasting, and deep learning where itearns its complexity. Experimentation & Causal Inference (technical): Design A/B tests and holdouts forcampaigns, offers and program changes, including power analysis and sample sizing.Apply uplift modeling and causal methods (diff-in-diff, propensity matching) to measurethe true incremental impact of loyalty initiatives when randomization is not possible. Feature Engineering & Data Pipelines (technical): Build and maintain reusable featuresets from large transactional and behavioral datasets. Work with Data Engineering ondata quality, lineage and scalable processing in the data warehouse and cloud platform. Client Engagement & Insight Delivery (business): Partner with client stakeholders toframe business questions as modeling problems, define success metrics, and presentresults and recommendations in executive reviews.
