About the role

<h2>The Role </h2> Green Thumb Industries is building a data science function that powers real operational decisions — demand forecasting that drives inventory positioning, analytics science that surfaces what's happening in our stores, and feature engineering that makes every model smarter over time.  This is a hands-on individual contributor role on a small, high-output, high-visibility team. You will spend your time building, testing, and maintaining ML models, engineering features, and translating data into answers that the business can act on. You will work closely with the Manager of Data Engineering, AI & ML, who will guide your technical direction and business context while you grow into shaping both. The systems are already starting to get built — your job is to push them further.  This is a hybrid role and requires in office work 1 day per week every 2 weeks at our office in River North in downtown Chicago.  <h2>Responsibilities </h2> ML Forecasting  <ul> <li data-leveltext="" data-font="Symbol" data-listid="1"
