Qualifications

• B.S. or M.S. in CS, Cybersecurity, or related field, or equivalent experience.
• 8+ years of hands-on security engineering in one or more domains: detection engineering, threat intelligence, incident response, cloud security, adversary simulation, offensive security, mobile/platform security, digital forensics, trust and safety
• Deep expertise in attacker tactics, techniques, and procedures with demonstrated ability to advance the state of the art
• Proficiency in coding with experience in languages such as Python or Rust
• Track record of architecting security systems or programs that operate at scale and influence how others build
• Demonstrated ability to define and drive complex, ambiguous problem spaces with group-level impact
• Experience in driving alignment and resolution across multiple teams and cross-functional partners

Responsibilities

• Architect security systems and capabilities that set the standard across teams
• drive platform-level decisions for AI-driven security solutions at Meta's scale
• Lead the strategy and methodology for adversarial research, threat intelligence programs, detection systems, or investigation capabilities augmented by AI
• Shape how security expertise translates into AI capability: define the methodologies that make model improvement systematic and scalable
• Set and improve quality standards for security engineering practices and processes across teams
• define processes and workflows that achieve scale and automation
• Drive cross-organizational partnerships that define how security and AI intersect: influence technical direction beyond the immediate team
• Break down problems into smaller, scoped workstreams, owning the most technically complex pieces while enabling others to execute against the overall solution
• Mentor other engineers across the organization, build a community, and act as a role model for security engineering practices and Meta values
• Drive team-wide adoption of practices and standards
• proactively communicate updates to leadership audiences
• Disseminate findings through internal publications, knowledge sharing, and contributions to the broader security community
