About the role

Security Engineer role in Meta’s Applied Artificial Intelligence (AAI) organization focused on solving hard security problems with AI-powered defenses, building security products/tools, and advancing AI-driven security capabilities across security, trust, and safety domains.

Responsibilities

  • Identify and solve ambiguous problems within a Security, Trust, or Safety domain where the solution and requirements are initially unknown, driving solutions that affect multiple teams
  • 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

Qualifications

  • 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
