The Sr. Data Scientist is an exceptional critical thinker comfortable leading end-to-end data science projects, and passionate about uncovering hidden opportunities deep within data. The Sr. Data Scientist works with business partners to define the business problem and creates a solution approach with small core project teams. This individual then takes the approach all the way to implementing data products, in collaboration with technology teams and other members of the Data Science team. The Sr. Data Scientist will lead data science work streams for the most difficult problems facing our Product functions in areas such as merchandising, merchandise planning, and allocations.

A day in the life

  • Lead data science projects from start to finish, identifying opportunities, defining the problem, building a proof of concept, and deploying a data product

  • Conduct data mining on guest, product, sales, assortment data sources for insights; generate hypotheses to test for opportunities in improving the merchandising and planning process

  • Apply a wide range of statistical and quantitative analysis in practical and valuable ways

  • Perform data pre-processing, data engineering, feature selection, model selection analysis

  • Participate in design workshops and document business requirements and constraints

  • Work closely with product managers to define requirements and design features

  • Program and write maintainable and well-documented scripts/applications for process automation; produce reusable machine learning pipelines while model building
