The Fraud Intelligence team is the analytical core behind Extend’s post-purchase protection platform. We turn signals and transactions from hundreds of millions of users into the insights that decide what we catch, what we stop, and what we let through.

Partner with the Machine Learning team to translate fraud pattern findings into model feature recommendations, and give feedback on model scoring based on investigation outcomes

Participate in design and code reviews, and mentor junior analysts on SQL and analysis best practices

What We’re Looking For: 

Hands-on, proactive, and analytical professional who is passionate about using data to solve complex, real-world problems
