AI-Driven Security Engineer – Applied AI

Meta; Topeka (KS); On-site; USD 154,000 - 217,000; Full time

Job summary

Meta is seeking a Security Engineer to join its Applied Artificial Intelligence (AAI) organization in the United States. The role blends hands-on security engineering with applied AI research to build novel AI-powered defenses and scalable AI-native security systems.

You will work with model researchers, engineers, and product teams to translate security expertise into training signals, evaluate AI models, and drive security innovations at Meta's scale.

Qualifications

• 5+ years of hands-on security engineering experience in detection engineering, threat intelligence, incident response, cloud security, or related domains.
• Extensive knowledge of attacker tactics, techniques, and procedures.
• Proficiency in coding with Python, Go, C/C++, or shell scripting.
• Experience building security systems, tools, or capabilities—not just identifying problems but engineering solutions.
• Ability to operate independently on complex security challenges.

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
