  • Develop custom data models and algorithms to apply to data sets
  • Assess the effectiveness and accuracy of new data sources and data gathering techniques
  • Develop processes and tools to monitor and analyze model performance and data accuracy
  • Interpret and communicate results to non-technical customers

What You Must Have:

  • Active security clearance required as part of client contract requirement
  • US Citizenship required as part of client contract requirements
  • Bachelor’s degree with a minimum of 12 years or Master’s degree with 10 years of experience in Computer Science, Statistics, Applied Mathematics, Computational Linguistics, Artificial Intelligence or related field

  • Strong experience using a variety of mathematical, statistical, data mining, and data analysis methods/tools

Preferred Skills/Experience:
