  • Write clean, well-tested code, and work with engineering to bring models and features into production.
  • Partner with the score monitoring team to help set up model and feature monitoring, and support research on related client questions.
  • Help prepare analyses and communicate findings to both technical and nontechnical audiences.
  • Apply Experian's standards for data privacy, model documentation, explainability, validation, and governance.
