- Apply traditional model development techniques and approaches (e.g. logistic regression) as well as adopting new AI/ML techniques such as gradient boosting, random forests, clustering, etc.
- Utilise the latest cloud based technologies and analytical tooling to support test-and-learn champion/challenger approaches towards new fraud scores and models
- Consider the creation of new characteristics/attributes to improve and maximise the predictive power of the model(s) as well as enhancing and creating other analytical products and services. This can be done through expert approaches or through AI approaches (e.g. transformers)
- Investigate and apply appropriate segmentation and sub-populations to maximise overall model & score performance

- Work closely with Data Scientists and analytical teams globally across the Equifax business to share best practice and learnings
- Adhere to relevant model development policies and procedures towards a successful deployment of scores and models e.g. sample design, good/bad definitions, rationale for exclusions, model development, model validation, implementation, etc.
- Produce suitable documentation alongside the statistical development of the model(s) to support peer review and Model Risk Management processes
