Research Scientist / Research Engineer, Search Integrity

Job summary

Responsibilities

We’re looking for a Researcher to lead Search Integrity: the systems that distinguish useful web content from spam, manipulation, and other adversarial or low-quality material.

• Define the technical direction for Search Integrity, identifying gaps and determining which problems and interventions to prioritize.
• Develop AI and ML systems to detect spam, scams, phishing, malicious domains, prompt injections, and other adversarial or low-quality web content.
• Discover useful signals across page content, links, domains, metadata, and relationships between websites, including patterns that reveal coordinated manipulation.
• Build evaluations that measure detection quality and how integrity interventions affect the information Search surfaces.
• Translate detection signals into indexing, ranking, and filtering decisions, improving what models can retrieve and rely on.

What they're looking for

• Deep experience in web spam, search quality, adversarial content detection, or related integrity problems at scale.
• Strong applied ML and research skills, with experience developing classifiers, detection methods, and evaluations for real-world systems.
• An understanding of how adversaries manipulate content and links, coordinate across sites, and adapt to detection systems.
• A track record of independently defining ambiguous technical problems and driving solutions from experimentation through production.
• Experience working across research, engineering, and integrity teams while remaining hands-on with technical work.
