We're looking for a Security Engineer Lead to scope, design, and champion security solutions company-wide across the domains we support.
Security Foundations is Meta's first-line-of-defense technology organization, owning the controls that manage security risk across the company. We're looking for a Security Engineer Lead to scope, design, and champion security solutions company-wide across the domains we support.
This is a breadth role. Each domain below has its own engineering leaders and managers — you will set technical direction across them rather than owning one. The hardest problems in this space does not sit inside a single domain. Agent identity and authorization, for example, spans identity and access, product authentication, AI security, and cloud simultaneously. Finding those problems and getting them solved once, coherently, is central to this role.
Identity and Access Management — the authorization layer every Meta system depends on, serving tens of billions of access checks per second
Cryptography and Data Security — including Meta's post-quantum migration and Encryption at Rest
Product Identity and Access — authentication for billions of end users
AI Security — the controls protecting Meta's frontier AI products
Cloud Security — securing Meta's footprint across public cloud and third-party compute providers, including identity, network egress, and posture management
Asset Management — authoritative security risk classification for assets across the company
Security Foundations is a cross-functional organization of engineers, analysts, and product managers, partnering closely with hundreds of engineers elsewhere in the company. The role spans a large set of technical domains: Meta's products and custom technology stack, commercial off-the-shelf software (e.g. Active Directory), and commercial IaaS/PaaS services. Familiarity with industry best practices and relevant regulatory frameworks — plus the ability to translate between those frameworks and deeply technical software engineers.
