You should be able to look at a retail transaction feed and design the model, not just query it. * Advanced SQL and production-grade Python (pandas, scikit-learn, statsmodels); comfort with at least one of PyTorch/TensorFlow, Prophet/ARIMA-family forecasting, or causal inference frameworks. * Demonstrated experience with time series forecasting and/or econometric modeling (elasticity, uplift, incrementality). * Cloud data platform experience (Snowflake, Databricks, Azure/AWS/Google Cloud Platform) and familiarity with CI/CD and version control practice. * Ability to work directly with clients: run a working session, handle pushback on methodology, and write a deck that a merchant will actually read. * Bachelor's degree in a quantitative discipline., * Mathematics, Statistics, or Operations Research major - we specifically value candidates with formal mathematical training and the ability to reason from first principles about optimization, probability, and model assumptions. * Advanced degree (MS/PhD) in a quantitative field. * Retail domain knowledge: open-to-buy, allocation, replenishment, size/pack optimization, omnichannel inventory, RFM and loyalty analytics. * LLM/GenAI application experience in a retail context (demand sensing, agentic workflows, unstructured product or review data). * Consulting or professional services background. * Experience with retail systems data a plus- SAP, Salesforce Commerce Cloud, O9. ## Description * Own end-to-end delivery on retail analytics engagements: discovery, data assessment, feature design, modeling, validation, deployment handoff, and results readout. * Build and productionize models across the retail value chain - demand forecasting and inventory optimization, customer segmentation and CLV, price/promo elasticity and markdown optimization, assortment and allocation. * Design data models and semantic layers on client data platforms (Snowflake, Databricks, Fabric, BigQuery); work with data engineering to define the tables the models actually need rather than accepting what exists. * Interrogate data quality and business logic before modeling - retail data is messy, and identifying the flaw in a returns table or a channel attribution rule is often worth more than a better algorithm. * Present findings to director- and VP-level client stakeholders; quantify business impact in margin, sell-through, GMROI, or working capital terms, not model metrics. * Support pre-sales: solution shaping, estimation, POC design, and technical credibility in client pitches. * Mentor junior analysts and contribute reusable accelerators to the retail practice. ## Related Videos - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [Photonic Computing: Programming a New Class of AI Accelerators (incl.
