As a member of our Account Fraud team, you'll investigate escalated account takeover cases, assess account security, coordinate containment and recovery efforts, and communicate directly with customers through some of their most stressful moments. You'll balance decisive risk management with empathy, helping customers regain confidence while ensuring the security of their accounts.
