Applied AI Security Engineer: AI-Driven Defenses

Meta; Frankfort (KY); On-site; USD 184,000 - 257,000; Full time

Job summary

Meta is seeking Security Engineers for the Applied AI Security group to tackle hard security problems at the intersection of AI and security. You will design AI-powered defenses, prototype AI-driven security capabilities, and translate security expertise into scalable AI-native systems.

The role blends hands-on security engineering with applied research across detection, threat intelligence, cloud security, and adversary simulation, reporting into the AI security leadership.

Qualifications

• 8+ years of hands-on security engineering experience across domains such as 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

• 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.
