Senior Data Scientist (Python, SQL)

Position Description:

  • A data scientist will develop machine learning, data mining, statistical and graph-based algorithms to analyze and make sense of datasets; prototype or consider several algorithms and decide upon final model based on suitable performance metrics; build models or develop experiments to generate data when training or example datasets are unavailable; generate reports and visualizations that summarize datasets and provide data-driven insights to customers; partner with subject matter experts to translate manual data analysis into automated analytics; implement prototype algorithms within production frameworks for integration into analyst workflows.

Labor Requirements:

  • Produce data visualizations that provide insight into dataset structure and meaning
  • Work with subject matters experts (SMEs) to identify important information in raw data and develop scripts that extract this information from a variety of data formats (e.g., SQL tables, structured metadata, network logs)
  • Incorporate SME input into feature vectors suitable for analytic development and testing
  • Translate customer qualitative analysis process and goals into quantitative formulations that are coded into software prototypes
  • Develop and implement statistical, machine learning, and heuristic techniques to create descriptive, predictive, and prescriptive analytics
  • Develop statistical tests to make data-driven recommendations and decisions
  • Develop experiments to collect data or models to simulate data when required data are unavailable
  • Develop feature vectors for input into machine learning algorithms
  • Identify the most appropriate algorithm for a given dataset and tune input and model parameters
  • Evaluate and validate the performance of analytics using standard techniques and metrics (e.g. cross validation, ROC curves, confusion matrices)
  • Oversee the development of individual analytic efforts and guide team in analytic development process
  • Guide analytic development toward solutions that can scale to large datasets
  • Partner with software engineers and cloud developers to develop production analytics
  • Develop and train machine learning systems based on statistical analysis of data characteristics to support mission automation
  • Lead a team of data scientists in the development of multiple analytic efforts
  • Work with customers and SMEs to define analytic requirements and guide the team in formulating analytics that meet requirements
  • Guide the transition of prototyped analytics to production system
  • Understand emerging machine learning and pattern recognition algorithms and guide a team of data scientists in integrating state-of-the-art algorithms into solutions
  • Delegate analysis responsibilities to one or more team members and monitor performance.

Minimum Experience Required:

  • Bachelor’s and Master’s degree or higher from an accredited college or university in a quantitative discipline (e.g., statistics, mathematics, operations research, engineering or computer science).
  • Ten (10) years of experience analyzing datasets and developing analytics, and ten years of experience programming with data analysis software such as R, Python, SAS, or MATLAB.
  • An additional two years of experience in software development, cloud development, analyzing datasets, or developing descriptive, predictive, and prescriptive analytics can be substituted for a Master’s degree.
  • A PhD from an accredited college or university in a quantitative discipline can be substituted for four years of experience.
  • TS/SCI with Polygraph Required
