  • Develop production-ready code and/or partner with engineering to deploy models/rules in the production environment
  • Contribute to fraud and abuse related incident response

  • Strategic-minded, impact-driven, and able to incorporate a larger business context into data questions and product development.
  • Experienced in building real-world machine learning models with demonstrated impact
  • Adept in Data Processing; performing essential data preprocessing tasks, applying data transformation, normalization, and feature engineering to prepare datasets for analysis.

  • Preferred Qualifications:
