• Build account, session, device, and credential lifecycle systems
• Solve security problems for AI, agentic, and tool-use surfaces
• Implement privacy-preserving identifiers and data retention, deletion, and minimization controls
• Emit durable and queryable security-relevant product events
• Ship security-sensitive request paths, integrations, data models, telemetry, migrations, and rollout controls
• Integrate third-party security and trust services with conservative failure behavior
• Own application security across product APIs and browser surfaces
• Build security libraries, middleware, tests, and platform patterns
• Lead threat modeling and implement fixes in the codebase
