Manager, Data Scientist - Card Payment Fraud Prevention

Capital One Capital One · Banking · McLean, VA +2

Manager, Data Scientist focused on Card Payment Fraud Prevention. The role involves building and deploying machine learning models for fraud detection across billions of transactions. It emphasizes traditional ML development with some exposure to GenAI, production deployment, model risk management, and regulatory compliance within a fintech domain. The role requires leading a team and collaborating with cross-functional partners.

What you'd actually do

  1. Partner with a cross-functional team of data scientists, software engineers, and product managers to deliver a product customers love
  2. Leverage a broad stack of technologies — Python, Conda, AWS, H2O, Spark, and more — to reveal the insights hidden within huge volumes of numeric and textual data
  3. Build machine learning models through all phases of development, from design through training, evaluation, validation, and implementation, monitoring, and supporting continuous model deployment and maintenance in a production environment.
  4. Collaborate on the design and maintenance of production data science solutions, including writing clear technical documentation and ensuring models adhere to software development best practices.
  5. Manage model risk and maintain regulatory compliance across the model lifecycle, which includes maintaining model inventory records, executing model testing and change control protocols, and collaborating on independent model validation and compliance risk assessments.
