Senior Software Engineer

Ballerine is a leading AI-native risk platform that uncovers and stops scams, fraud, and other bad actors before they enter financial systems.

We scan and interpret the entire digital footprint of a business - from websites and social media to hidden online mentions - revealing who they really are and whether they pose a risk.
