Sr. Staff Product Manager, Adversarial Actors

Role overview Set the product strategy for identifying and reducing inauthentic activity across a large online service. The scope spans the user journey from account creation and login through authenticated use, with a particular focus on spam accounts and domains, account takeovers, detection quality, and effective enforcement.

Responsibilities - Define a multi-year strategy covering abuse before and after authentication, align senior stakeholders, and coordinate investment across partner teams. - Own the post-authentication roadmap for measurement, detection signals, and enforcement; coordinate with the product lead covering pre-authentication abuse. - Work with engineering and data science to develop network signals, machine-learning models, and rules for detecting spam accounts and domains. - Partner with enforcement teams on interventions such as warnings, rate limits, feature restrictions, account deactivation, and domain-level actions. - Establish measures for spam prevalence, detection quality, and enforcement effectiveness. - Track emerging abuse patterns and adjust priorities while weighing safety outcomes against the impact of false positives.

Requirements - 10+ years of product management experience, with deep expertise in trust and safety, account integrity, anti-abuse, or related work. - Track record delivering machine-learning-based detection products and enforcement systems at scale. - Strong data fluency, including precision, recall, false-positive rates, prevalence measurement, and adversarial behavior. - Proficiency in SQL for independent data investigation and analysis. - Systems thinking for complex, connected detection and enforcement infrastructure. - Cross-functional leadership, executive communication, and sound judgment on policy and enforcement tradeoffs. - Bachelor’s degree in a relevant field or equivalent experience.
