Note: The job is a remote job and is open to candidates in USA. Meta is seeking a Security Engineer Lead to set technical direction for company-wide security solutions across Security Foundations’ domains. The role identifies and models security risks, drives shared platform and control design and implementation, and represents security tradeoffs to senior leadership.

Responsibilities

• Set technical direction for security solutions and platforms shared across the company, working through Security Engineering, Security Analyst, and Software Engineering teams
• Determine the highest-risk items across these domains company-wide, then lead development of detailed threat models and solutions
• Define how AI agents are identified, authorized, and audited across Meta's infrastructure — a space where neither existing industry practice nor our own human-centric models are sufficient
• Navigate tradeoffs between security and friction or cost, so the company can keep moving fast securely
• Drive solution design, including technical architecture, and lead implementation as needed
• Build partnerships across security, infrastructure, corporate engineering, and legal — then use those partnerships to translate ambiguous business and regulatory requirements into well-articulated tradeoffs between "secure the company and our users" and "slow the company down."
• Represent those tradeoffs credibly to senior leadership, including VPs and C-level executives (CTO, CISO), to drive decisions

Skills

• B.S. Computer Science or related field
• Deep technical expertise in at least one of these domains, and a demonstrated ability to become credible quickly in unfamiliar ones
• Significant experience in driving large cross-company engineering initiatives
• Experience managing security risk and navigating the tradeoff between security and friction in a large organization
• Experience communicating and influencing across functions to drive solutions
• Ability to operate in high-ambiguity environments and balance technical solution design with complex business processes and requirements
• Hands-on engineering experience and the ability to lead across a blended Security Engineering and Software Engineering organization
• Experience with identity and access management, cryptographic systems and massively scaled infrastructure
• Experience securing AI/ML systems or agentic workloads
• Familiarity with SOX, SOC 2, or comparable control frameworks and the engineering work required to satisfy them
• Experience leading security work spanning both production (Linux) and corporate (Windows, Active Directory, SaaS) environments

Benefits

• Bonus
• Equity
