Pyramid Overview A role with Target Data Science & Engineering offers the opportunity to develop, deploy, and operate state-of-the-art algorithmic systems that use data at scale to automate, personalize, and optimize business decisions. Our teams apply machine learning, statistics, operations research, simulation, optimization, and AI engineering to solve complex retail problems across Marketing, Personalization, Supply Chain, Merchandising, Finance, Network Security, and Guest Experience.You will work with Target’s rich data ecosystem and partner with product, engineering, analytics, and business teams to create scalable decisioning systems that deliver measurable business and guest impact.

Team Overview The MarTech team, Calibrate, owns and evolves Target’s promotion segmentation and offer optimization engine. The team powers personalized offers and offer depths for Target Circle guests across the retail assortment. We build machine learning, causal inference, optimization, simulation, and Generative AI capabilities to decide which guests should receive which offers, at what value, through which channels, and under what business constraints. The team is responsible not only for model development, but also for production deployment, monitoring, experimentation, performance measurement, and continuous improvement. Our work sits at the intersection of Marketing Science, personalization, decision optimization, and enterprise-scale AI platforms.

Position Overview As a Senior Data Scientist, you will be a hands-on technical contributor and problem solver responsible for designing, developing, deploying, and improving scalable data science solutions for retail promotion optimization. You will work across machine learning, operations research, experimentation, and AI engineering / MLOps to build models and decision engines that drive incremental sales, improve redemption, optimize offer investment, and enhance guest relevance. You will collaborate closely with product managers, engineers, data scientists, analysts, and Marketing business partners to translate ambiguous business problems into well-defined analytical, algorithmic, and engineering solutions. You will contribute to the full lifecycle of data science products: opportunity sizing, data exploration, model development, optimization formulation, offline evaluation, production deployment, monitoring, and iterative improvement. You will also mentor junior team members, uphold high standards for scientific rigor and engineering quality, and help shape reusable frameworks for experimentation, simulation, model operations, and decision intelligence.
