The Data Scientist is responsible for analyzing large data sets
to develop custom models and algorithms to drive business
solutions. The Data Scientists work on project teams in order to
provide analytical support to projects (for example, email
targeting, business optimization, consumer recommendations) for
Walmart eCommerce. They are responsible for building large data
sets from multiple sources in order to build algorithms for
predicting future data characteristics. Those algorithms will be
tested, validated, and applied to large data sets. They are also
responsible for training the algorithms so they can be applied to
future data sets and provide the appropriate search results. Data
Scientists are responsible for researching new trends in the
industry and utilizing up-to-date technology (for example, HBase,
MapReduce, LAPack, Gurobi) and analytical skills to support their
