Work with data engineers and other technical teams to support better pipelines, data quality checks, and more reliable monitoring inputs
Support the development of internal scoring approaches and future machine learning use cases as the function evolves
Translate complex analysis into clear recommendations that improve fraud prevention while minimising friction for legitimate customers
Requirements
Strong experience in fraud detection or transaction monitoring analytics
Proven ability to improve rules, controls, or detection logic using data
