AI-Driven Security Engineer (Applied AI)

Meta; New York (NY); On-site; USD 154,000 - 217,000; Full time

Job summary

Meta is seeking a Security Engineer for its Applied AI (AAI) organization. You will blend hands-on security engineering with applied research to design, prototype, and deploy AI-augmented security solutions at Meta-scale.

You will contribute to threat intelligence, detection engineering, and platform security research, while partnering with model researchers to create training signals that help models reason like security experts.

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.
• Proficiency in coding with experience in languages such as Python, Go, C/C++, or shell scripting

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
