As a Senior Fraud Analyst, you will lead research into emerging fraud trends, typologies, and

attack vectors to keep the company ahead of evolving threats, while supporting the detection,

investigation, and mitigation of fraudulent activity across the business. You'll conduct deep-dive

analysis across large datasets and historical fraud patterns to uncover fraud rings and behavioral

clusters that inform detection strategy, and you'll build and maintain the methodologies and

processes used to track the company's risk metrics. You will track how fraud tactics shift across

geographies and payment methods, and translate those findings into actionable insights for

internal teams building or tuning models. Strong analytical and statistical skills, comfort working

with large and messy datasets, and genuine curiosity about how fraudsters adapt are essential,

along with the ability to clearly communicate complex findings to both technical and

non-technical audiences while maintaining strict confidentiality around sensitive data.
