Full Job Description
Description

This role is a client-facing data scientist supporting enterprise retail accounts across merchandising, supply chain, customer, and pricing analytics. You'll work embedded with client teams - scoping the problem, building the model, and defending the methodology to business stakeholders who are not data people. This is a consulting role: billable, multi-account, and dependent on your ability to translate ambiguous business questions into tractable modeling problems.

Responsibilities:
  • 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.


Qualifications:

  • Five+ years applied data science experience, with meaningful time on retail, CPG, or e-commerce problems.
  • Strong data modeling fundamentals - dimensional modeling, star/snowflake schemas, slowly changing dimensions, grain definition. 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/GCP) 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.


Preferred Qualifications:
  • 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.

Pay rate: $130,000 to $150,000/year
