Enterprise Application Security Engineer (Builder)

Meta's Enterprise Application Security team is seeking a security engineer with proven experience identifying weaknesses and crafting creative solutions to eliminate those weaknesses at scale. We secure and harden the enterprise applications Meta runs on, both first-party and third-party, and we protect the sensitive data they hold. We don't just identify and help fix security vulnerabilities, we go beyond by preventing security problems before they exist. Our scope includes securing how Meta adopts third-party AI applications and agentic workflows across the enterprise, a high-priority area with significant visibility across the company. You will be expected to collaborate technically with developers and engineers across large organizations, and you will be relied upon to provide application and infrastructure teams with the security expertise necessary to build the secure enterprise that underpins Meta.
