Job description
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.
Responsibilities
ML Forecasting
- Build, validate, and refine demand forecasting models for GTI's retail, wholesale, and other emerging business verticals across daily, weekly, monthly, and quarterly forecast horizons
- Engineer new features for the Snowflake Feature Store - drawing from retail sales history, inventory movement, weather data, customer demographics, and external signals - to improve model accuracy across store, product, market and other dimensions
- Develop and test new model candidates against GTI's established backtesting framework; interpret backtest results and surface findings to inform promotion decisions
- Investigate forecasting errors and anomalies: identify when model performance degrades, diagnose root causes (data drift, structural breaks, new store openings, regulatory changes), and propose remediation
- Conduct dimensionality reduction and principal component analysis to understand primary feature importance
- Collaborate with the Manager to evolve the feature engineering roadmap - identifying signals worth building, data gaps worth closing, and model architectures worth exploring
Analytics Science
- Design, validate, and execute analytical studies that answer business-user's operational questions which can then be modeled and replicated by our data analyst AI agent to further promote self-service
- Build reusable analytical frameworks on top of GTI's curated data layer (retail sales, inventory, customer, loyalty, workforce) that can be repeated, parameterized, and handed off to the business
- Contribute to quasi-experimental modeling: pre/post adult-use launch performance, store cohort comparisons, product mix attribution, and discount effectiveness
- Translate analytical findings into clear written summaries and visualizations that non-technical stakeholders can act on
- Identify patterns in the data that surface new questions worth asking - and bring those to strategy discussions with the Manager
Collaboration & Growth
- Participate in team roadmap and design discussions; contribute your analytical perspective on what problems are worth solving and how
- Learn GTI's production data stack (Snowflake, dbt, Dagster) and the curated data models that underpin all analytical work - these are your primary data surfaces
- Over time, develop familiarity with GTI's Snowflake based AI agent ecosystem and how structured analytical outputs feed into natural language intelligence tooling
- 2+ years of hands-on experience in a data science, quantitative analyst, or ML engineering role - with demonstrable work in model building, feature engineering, or statistical analysis
- Strong Python skills for data manipulation, modeling, and analysis (pandas, scikit-learn, statsmodels, or equivalent). Jupyter notebook development or equivalent experience
- Strong SQL skills - comfortable writing complex queries across multiple joined tables, aggregating at multiple grains, and debugging data quality issues in query output, while validating accuracy and trust
- Working experience with supervised and unsupervised ML methods: gradient boosting, time series models, random forest, decision trees, etc
- Ability to communicate analytical findings clearly in writing - you don't just run the analysis, you explain what it means and what to do about it
- Intellectual curiosity and a bias toward figuring things out - this role requires navigating real, messy data in a complex multi-state retail operation
Preferred
- Experience with time series forecasting methodologies (ARIMA, Prophet, LightGBM/XGBoost for tabular time series, or similar)
- Experience with advanced machine learning modeling techniques and algorithms such as Bayesian inference, Deep Learning neural networks, k-means clustering, etc
- Familiarity with feature store concepts or structured feature engineering pipelines
- Exposure to Snowflake, Snowpark, or cloud data warehouse environments
- Experience with dbt or working in a layered data warehouse (raw → refined → curated) - understanding where data comes from matters here
- Experience prototyping and productionizing data products such as Streamlit apps
- Basic familiarity with LLM-powered tooling or AI agent frameworks - not required, but exposure gives you context for where the team is headed
- Background in retail, CPG, consumer analytics, or any multi-location operations business
- Must pass any and all required background checks
- Must be and remain compliant with all legal or company regulations for working in the industry
- Must be a minimum of 21 years of age

Frequently asked questions
Q: What skills or qualities help someone succeed as a Data Scientist?
A: To succeed as a Data Scientist, one must possess core technical skills such as proficiency in programming languages like Python, R, or SQL, as well as expertise in machine learning algorithms, data visualization tools like Tableau or Power BI, and statistical modeling techniques. Additionally, strong soft skills like effective communication, collaboration, and problem-solving abilities, along with traits like curiosity, adaptability, and attention to detail, are crucial for success in this role. By combining these technical and soft skills, Data Scientists can effectively extract insights from complex data, drive business decisions, and drive career growth through continuous learning and innovation.
Q: What is the career path for a Data Scientist?
A: A Data Scientist's typical career progression involves starting as a Junior Data Analyst or Data Scientist, where they develop foundational skills in data analysis, machine learning, and visualization. As they gain experience, they can move into mid-level roles such as Senior Data Scientist or Lead Data Analyst, where they take on more complex projects, mentor junior team members, and contribute to strategic decision-making. Ultimately, senior Data Scientists can transition into leadership positions like Director of Data Science or Chief Data Officer, or pursue specialized roles like Data Engineering or Artificial Intelligence Research Scientist, depending on their interests and skills.
