You will have end-to-end ownership to establish the strategy, build foundational detection playbooks, and define enforcement frameworks. You will work in tight partnership with cross-functional Product, Engineering, Data Science, and Ops teams across both Safety and Ads orgs to convert adversarial insights into scalable automated defenses. This is a 0-to-1 opportunity to shape our threat response frameworks, operational playbooks, and detection pipelines from scratch.

- Demonstrated 0-to-1 track record of operating in ambiguous environments to build threat response frameworks.

Responsibilities
- Formulate and execute a multi-quarter vision for advertiser fraud detection and enforcement; independently prioritize high-impact risks like account takeover (ATO), payment/billing fraud, cloaking, deceptive ads and network abuse.
