You’ve helped build tools, models and detection platforms at companies that have had to work through these threats at a global level. What you’ll do Work with our Trust and Safety Architect and Data Science teams to surface emerging fraud patterns across the network escape and proactively take them down. Detect patterns and turn those findings into sharper signals, tighter configurations, and smarter decisioning logic.
