Responsibilities Develop a deep understanding of the fraud and abuse landscape. Investigate emerging attacks with customers, assess their financial and operational impact, and distinguish isolated incidents from opportunities to build broadly useful defenses. Translate findings into a product strategy and roadmap, prioritizing the defenses that deliver the greatest customer and business impact. Partner with engineer
