About the Role:

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.

We love uncovering patterns in messy data to catch bad actors, and fraud doesn't stand still. The work moves quickly: a new tactic shows up, you find it in the data, and you help shut it down. You'll work on the front line of how AI is changing fraud review, alongside Fraud Ops and our Machine Learning team, so your analysis turns into material changes, not just a slide.

• Evaluate Fraud Ops' AI review agent, both the quality of its case summaries and the accuracy of its recommended decisions, and turn what you find into prompt, rule, and workflow improvements
• 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

• Exceptional communication and stakeholder management skills, with a proven ability to work cross-functionally and influence outcomes
