• Partner with Internal Audit teams to design data‑driven testing strategies for audits spanning e‑commerce, ads, trust & safety, platform integrity, payments, infrastructure and security.
• Translate audit objectives, risk hypotheses, and control designs into scalable analytical tests, metrics, and models.
• Provide hands‑on analytics support for audit engagements, including: understanding end‑to‑end business and product workflows, conducting stakeholder interviews and system walkthroughs, developing complex queries and analytical logic, performing population completeness, accuracy, and integrity testing, identifying anomalies, trends, and risk signals, and defining and monitoring key risk indicators (KRIs) and risk‑aligned metrics embedded within product and operational data.
• Analyze user behavior, monetization flows, content or transaction life cycles, and system events to identify emerging or systemic risks.
• Bridge traditional audit concepts with modern data and product to surface insights not discoverable through manual testing.
• Data inventory and lineage: develop a deep understanding of the company’s data ecosystem, including applications, event streams, operational databases, and data warehouses; identify and maintain an inventory of critical data assets relevant to audit and risk use cases; assess data lineage, ownership, and reliability to support audit defensibility and repeatability.
