Postdoctoral In Reinforcement Learning Jobs in Fort Mill, SC

What you will do

• Maintain and optimize existing propensity and response models (purchase, churn, reactivation, category affinity, channel, promotion, and creative recommendations) to ensure ongoing accuracy and effectiveness at the individual customer level.
• Monitor model performance and health, including drift detection, retraining cycles, validation, and continuous improvement of marketing decisioning models.
• Support model deployment and operations within real-time and near-real-time marketing environments, partnering with Marketing Technology teams to maintain scoring and decisioning capabilities.
• Execute and analyze A/B, multivariate, holdout, and incrementality tests to evaluate model performance and measure marketing-driven lift.
• Translate model outputs into actionable marketing strategies by partnering with campaign and CRM teams to develop audience segments, suppression lists, and treatment assignments.
• Apply and support marketing optimization frameworks that balance short-term revenue objectives with long-term customer lifetime value (CLV) growth.
• Develop, maintain, and enhance customer-level predictive features and feature stores using transactional, behavioral, engagement, loyalty, and third-party data sources.
• Analyze customer behavior and segmentation data to deepen understanding of loyalty tiers, shopping occasions, affinities, channel responsiveness, and promotional sensitivity.
• Develop, maintain, and troubleshoot production-quality analytics solutions, including Python/R model code, feature engineering workflows, and SQL-based data pipelines.
• Prepare, validate, and manage modeling datasets and scoring processes to support reliable model execution and reproducibility.
• Document model methodologies, assumptions, performance results, and governance requirements to ensure transparency, compliance, and operational continuity.
• Communicate model performance and analytical insights to business stakeholders, translating technical findings into clear recommendations while supporting cross-functional collaboration and ongoing professional development.
