Work with business owners to map business requirements into technical solutions
Perform ad hoc statistical, data mining, and machine learning analyses

Experience with a high-level statistical modeling tool such as R or Matlab
Solid understand of the theory and practice of machine learning algorithms, including deep learning and ensemble techniques
Strong software development skills in Python or C
Experience developing and implementing predictive models in a product development environment
Experience with statistical error estimation techniques such as cross-validation and the bootstrap

Additional Desired Skills and Qualifications:
M.S. in statistics, electrical engineering, or computer science (Ph.D. strongly preferred)
Minimum of five years experience applying machine learning techniques to real business problems
High intellect and ability to solve extremely challenging predictive modeling problems applied to a variety of different domains
