Security Engineer - Applied AI

Meta; City of Albany (NY); On-site; USD 184,000 - 257,000; Full time

Job summary

Meta is seeking Security Engineers to join the Applied AI Institute (AAI) security group. You will blend deep security expertise with frontier AI, building defenses, researching adversaries, and shaping how AI capabilities secure Meta's systems at scale.

You will design security architectures, lead adversarial research programs, and mentor teams, delivering AI-enhanced security products and transparent, responsible security practices across Trust and Safety.

Qualifications

• 8+ years of hands-on security engineering experience.
• Proficiency in Python or Rust.
• Experience architecting security systems at scale.
• Ability to define and drive complex, ambiguous problem spaces with impact.
• Strong cross-functional collaboration with multiple teams.
• Experience in threat intelligence, incident response, or cloud security.

Responsibilities

• Identify and solve ambiguous problems within a Security, Trust, or Safety domain.
• 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.

Job description

Summary:

Meta is seeking Security Engineers to join our Applied Artificial Intelligence (AAI) organization. As a Security Engineer in AAI, you will apply deep domain expertise to solve hard, real-world security problems, building novel security capabilities, prototyping AI-powered defenses, and advancing the frontier of what AI systems can do in Security, Trust, and Safety. Your work is AI-augmented from day one: you leverage AI tools and agents to accelerate your impact, and where the models fall short, your expertise directly drives their improvement.You will blend hands‑on security engineering with applied research: designing and executing novel approaches to security challenges that push both the state of Meta's security posture and the state of the art in AI‑driven security. This includes building security products and tools, conducting original adversary research, developing detection and response capabilities, and translating security expertise into scalable, AI‑native systems. Your domain knowledge — whether in detection engineering, threat intelligence and adversarial analysis, cloud security, adversary simulation, mobile and platform security, forensic investigation, or emerging areas like AI/ML security — becomes the foundation for capabilities no existing AI system can replicate.This role is for experienced security practitioners who want to operate at the intersection of deep security expertise and frontier AI — not just using AI as a tool, but shaping what it becomes.
