Security Foundations Lead: Cross‑Domain Security Architect

Meta; Lincoln (NE); On-site; USD 271,000 - 347,000; Full time

Benefits offered by this job

Job summary

Meta is seeking a Security Engineer Lead to scope, design, and champion security solutions across domains, from identity and access to AI security and cloud. This breadth role sets technical direction across multiple engineering teams rather than owning a single domain.

You will build threat models, articulate tradeoffs to executives, and drive shared platforms adopted across the company. The role demands hands-on leadership, strong communication, and the ability to navigate high-ambiguity

Qualifications

• Minimum: B.S. in Computer Science or related field.
• Deep technical expertise in at least one domain and credibility in unfamiliar ones.
• Significant experience driving large cross-company engineering initiatives.
• Experience managing security risk and balancing security with friction.
• Experience communicating and influencing across functions.
• Ability to operate in high-ambiguity environments and balance design with business processes.
• Hands-on engineering experience leading blended security and software teams.

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.
