Data Scientist (Machine Learning (NLP)

Location Plano, United States
Posted 14-September-2021

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 assigned project.

Develop custom data models to drive innovative business solutions.

Work with cross-functional partners across the business.

Build complex data sets from multiple data sources, both internally and externally.

Conduct advanced statistical analysis to determine trends and significant data relationships.

Build learning systems to analyze and filter continuous data flows and offline data analysis.

Utilize system tools including (MySQL, Hadoop, Weka, R, Matlab,ILog)

- Understand different domains and identify problems that can leverage Machine Learning and Data Science in general.

- Extract, clean and scrub dataset from various sources like, distributed systems, databases etc. This typically is 60-70% time consuming task.

- Analysis of datasets and identifying problems to be solved. This requires a good understanding of domain, descriptive statistics and tests.

- Depending on the problem we build Time Series, Computer Vision, NLP or basic predictive models.
