About the job

The Ads Safety team is responsible for building systems that ensure safety, fairness, and trustworthiness. We review every ad, advertiser, publisher, and merchant in our ecosystem to ensure that they comply with ads policies and publisher controls. At Google’s scale, Ads Safety requires advanced machine learning and artificial intelligence, in-depth threat analysis, and a relentless focus on adapting to emerging risks. As a Principal Developer on the Ads Safety team you will be responsible for designing and advancing the technical road map for detecting malicious activity and evaluating ad content at massive volumes. This includes integrating robust ML models with verification and review frameworks, as well as partnering across policy, legal, and compliance teams to maintain alignment with regulatory standards and the highest levels of user trust. You will drive the technical vision and execution of machine learning solutions aimed at both Actor Safety and Content Safety. The actor dimension focuses on distinguishing legitimate users from malicious entities who may engage in fraud, scams, or counterfeit activities. The content dimension deals with ensuring that ad content complies with our policies, addresses user concerns, and avoids harmful or misleading information to our users.

Success in this role means delivering a secure and trustworthy advertising environment for users, advertisers, and publishers—and influencing the future of one of the world’s largest ad systems. You’ll shape the strategies that ensure Ads Safety remains at the forefront of innovation, responsibility, and trust. You will inspire high-performing team members dedicated to innovation, resilience, and the relentless pursuit of a secure and trustworthy advertising environment for users, advertisers, and publishers worldwide.

Google Ads is helping power the open internet with the best technology that connects and creates value for people, publishers, advertisers, and Google.
