Commerce is one of the biggest focus areas for Facebook in the coming decade, and Marketplace already has hundreds of millions of users. The mission of Actor Integrity is to protect users and our platform from harms like scams and harassment caused by bad actors who violate our standards and policies. There is broad cross-functional collaboration between DS and Engineering, Product Management, Operations, Data Engineering, Analysts, and more. Data Science plays a key role in driving strategic decisions within the team since data-driven understanding is critical to achieving success in this complex and dynamic space. We employ sophisticated machine learning models to catch fraud and malicious platform behavior at scale, so you’ll also work with the ML engineers on the team to support their approaches and experiments.

This role focuses on 4 key areas: Product success measurement: what goals should we set? How well are we progressing towards our goals? What moves our core metrics and why? What proxy metrics can help us make faster progress with directional validity and superior coverage & latency? Harm prioritization: where should we be investing to protect good users? How much improvement could we make via automated and manual defense systems? System maturity: how can we reduce the time from new exploits to remediation? What foundational investments will help us scale faster with higher quality? Which guardrails are most important? Unbiased estimation of sparse signals: with measurements of rare events, how can we keep track of what’s happening even when we only have partially observed data?
