• Support internal and external data needs across Fraud, Risk, Product, Engineering, Customer Success, and Compliance.

• Build and maintain dashboards, monitoring tools, and metrics that improve pipeline quality, data quality, and visibility into fraud trends.

• Translate business and investigative requirements into clear technical data designs, schemas, and analytical models.

• Collaborate with Product and Engineering teams to integrate fraud logic, data features, and detection insights into platform capabilities.

• Communicate complex fraud concepts and analytical findings in an understandable way to investigators, leadership, and customer-facing teams.

• Drive continuous improvement in fraud detection logic, expand coverage across scam scenarios, and proactively identify new areas of development.

• Maintain strong data governance, documentation, and integrity for all fraud-related datasets and processes.

We're looking for candidates who have:

• Hands-on experience with SQL databases, Python, data warehousing platforms, and a background in analytics.

• Experience managing data pipelines, ETL workflows, or real-time monitoring systems.

• Demonstrated success in building and managing a high-performing data or analytics team.

• Ability to communicate complex analytical concepts clearly to executives, customers, and cross-functional partners.
