The Data Scientist is a talented and experienced problem-solver, using analytic techniques to answer questions, identify opportunities, and make recommendations for our business. The scope of assignments will be broad, covering our client experience, operational efficiency and effectiveness, and financial and subscriber performance. They will be asked to perform the full life-cycle of data analysis, and to contribute to each step in a hands-on fashion.
MAJOR DUTIES AND RESPONSIBILITIES
- The Data Scientist will perform the full life-cycle of data analysis from definition of questions / issues to presentation of results and recommendations. This work will be carried out with close direction and dialog with the Director of Data Science and other Data Scientists, and with daily interactive participation with business and data SMEs across the organization.
- This life-cycle of data analysis includes hands-on iterative execution of these steps:
- Definition: Dialog and interview with key business stakeholders on the issues and questions to answer during analysis. Provide direction and suggestions based on experience in order to clearly articulate the business questions and manage the scope of analysis. Document an analysis charter that outlines scope and goals of analysis.
- Data Research: Using a variety of techniques, discover and research the available sources of data. These techniques should include discussion with data and system SMEs, use of data management assets such as documentation, database catalog tables, and data models, and the use of data profiling and exploratory data analysis.
- Data Preparation: Using SQL and DB techniques assemble the available data, performing necessary integration, summarization, and transformation of data in order to support the analysis goals.
- Data Analysis: Using basic and intermediate techniques such as crosstab analysis, charting, and geographic mapping, examine the data in the context of the issues at hand. Identify when more advanced techniques are required, such as statistical analysis, regression modeling, etc., and participate in the use of these techniques.
- Synthesis: Draw conclusions and make recommendations based on the observed patterns in the data. By sharing these conclusions for feedback and refinement, continuously improve the veracity and utility of the findings. In close dialog with the business SMEs, identify potential areas for further analysis, measurement, or business process change.
