Applied AI Security Engineer

Meta; Austin (TX); On-site; USD 154,000 - 217,000; Full time

Job summary

Meta is seeking a Security Engineer to join the Applied Artificial Intelligence (AAI) organization. You will apply deep security domain expertise to solve multi-step security problems, prototyping AI-powered defenses and advancing AI-driven security at scale.

The role blends hands-on security engineering with applied research, building security products, conducting adversary research, and translating security expertise into scalable AI-native systems.

Qualifications

• B.S. or M.S. in Computer Science, Cybersecurity, or 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

Responsibilities

• Apply deep security domain expertise to identify, scope, and solve complex security problems that require multi-step reasoning 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 signals and 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
