About the role

Security Engineer role within Meta's Applied Artificial Intelligence organization. Focus on solving real-world security problems with AI-augmented security engineering, building novel security capabilities, prototyping AI-powered defenses, and advancing AI-driven security at scale.

Responsibilities

  • Apply deep security domain expertise to identify, scope, and solve complex security problems that require multi-step reasoning, novel approaches, and expert judgment
  • Build security products, tools, and capabilities — prototyping AI-driven solutions to real-world security challenges at Meta's scale
  • Design and execute adversarial research, threat intelligence analysis, detection engineering, platform security research, or investigation workflows augmented by AI tools and agents
  • Identify where AI models lack security reasoning capability and directly contribute to improving them through expert-generated signals, evaluation, and feedback
  • Develop novel methodologies and reusable approaches that advance both Meta's security posture and AI system performance in security domains
  • Collaborate with model researchers to translate security expertise into training signal — decomposing hard problems into structured challenges that teach models to reason like security experts
  • Partner cross-functionally with engineering, product, and research teams to incorporate security innovations into production AI systems
  • Drive end-to-end execution of complex security initiatives with independence, contributing to the technical direction within the team
  • Disseminate findings through internal publications, knowledge sharing, and contributions to the broader security community

Qualifications

  • B.S. or M.S. in Computer Science, Cybersecurity, or a related field, or equivalent experience
  • 5+ years of hands-on security engineering experience in one or more domains: detection engineering, threat intelligence, incident response, cloud security, adversarial simulation, offensive security, mobile/platform security, or digital forensics
  • Extensive knowledge of attacker tactics, techniques, and procedures
  • Proficiency in coding with experience in languages such as Python, Go, C/C++, or shell scripting
  • Experience building security systems, tools, or capabilities — not just identifying problems but engineering solutions
  • Demonstrated ability to operate independently on complex, ambiguous security challenges
