  • Ability to solve complex problems with minimum supervision.
  • Critical thinking ability and ability to generate intuitive conclusions from complex datasets.
  • Excellent verbal and written communication skills, with high attention to detail.
  • Fluency in SQL and ability to write complex queries to extract large amounts of data.

  • Concrete understanding of machine learning algorithms (clustering, regression, and classification) and basic probability and statistics.
  • Experience with deep learning and natural language processing algorithms.
  • Experience with data science tools and frameworks such as scikit-learn, Keras, Tensorflow, H2O, Numpy, Pandas, Jupyter, etc.
  • Familiarity with online advertising and advertising fraud.
Preferred qualifications:
  • MS or PhD degree in Computer Science, Electrical Engineering, Math, Statistics, or other quantitative field.
  • A team player who can collaborate with engineers, product managers, and other cross-functional teams.
  • Ability to initiate and drive projects to completion with minimal guidance.
  • Demonstrable ability to quickly understand concepts.
  • Fullstack knowledge of the data science processes and frameworks.
  • Ability to communicate the results of analyses in a clear and effective manner to a senior audience
