Job description

The Trust and Safety Workspace Account Security and Integrity (AIS) team is dedicated to protecting Google Workspace and Cloud customers from account-based threats. The mission is to safeguard the integrity of Workspace accounts by delivering a unified, scalable defense against account hijacking, takeover (ATO), and malicious automation. We operate at the critical intersection of product security and abuse prevention, balancing robust security controls with a frictionless experience for both individual users and enterprise organizations. By studying adversarial behavior and building state-of-the-art telemetry and agentic defense systems, we ensure a secure, trusted, and resilient ecosystem that protects our customers' businesses, data, and users.

Job responsibilities

• Drive the technical strategy and threat modeling for Workspace account security, identifying systemic weaknesses in authentication, recovery, and API integration paths.
• Lead vulnerability research and adversarial simulation to expose novel account takeover (ATO) and "Made for Abuse" (MFA) techniques.
• Design and build advanced agentic systems, debugging tools, and simulators to autonomously detect, analyze, and mitigate complex account security threats.
• Architect and deploy customer-facing agentic tools that empower Workspace and Google Cloud customers to proactively monitor and secure their own environments.
• Lead the investigation of high-severity account security incidents, developing robust, long-term mitigations and patches in collaboration with Product Engineering teams.

• 1 year of experience leading teams in a technical capacity or leading technical risk analysis in an enterprise environment.

Preferred qualifications

• Master's degree or PhD in Computer Science, Cybersecurity, or a related technical field, or equivalent practical experience.
• Experience in account security mechanisms, identity and access management (IAM), and modern authentication standards (e.g., OAuth 2.0, OIDC, FIDO/Passkeys, SAML).
• Experience building or deploying AI agents, LLMs, or agentic workflows for security automation, threat detection, or user-facing product features.
• Understanding of anti-abuse systems, bot detection, and mitigations against malicious automation (credential stuffing, bulk creation).
• Ability to identify novel security vulnerabilities (e.g., threat research, bug bounties, security advisories) and implementing systemic engineering fixes.
