Original job description

Meta is seeking a Network Security Engineer to help protect and harden the global network infrastructure that underpins Meta's family of products and services. In this role, you will drive the design, implementation, and continuous improvement of security controls across Meta's large-scale network fabric, including edge, core, and data center environments. You will partner with network engineering, security operations, and product teams to identify vulnerabilities, define security architecture standards, and lead initiatives that reduce risk across the network infrastructure stack. This is a high-impact, technically deep role for an engineer who can operate at the intersection of network engineering and offensive and defensive security at global scale.

Responsibilities

Lead the design and implementation of network security architectures across edge, core, and data center infrastructure, including firewall policy frameworks, access control systems, and traffic inspection pipelines
Identify and remediate security vulnerabilities in network infrastructure through threat modeling, security assessments, and proactive risk analysis of routing protocols, switching fabrics, and network services
Define and drive adoption of network security standards, hardening guidelines, and secure configuration baselines across the infrastructure organization
Develop and maintain detection and monitoring capabilities for network-layer threats, including anomaly detection, traffic analysis, and intrusion detection systems at scale
Lead incident response efforts for network security events, conducting root cause analysis and driving systemic improvements to prevent recurrence
Collaborate with network engineering, security operations, and infrastructure teams to integrate security controls into network provisioning, automation, and change management workflows
Leverage AI-assisted tooling and automation to accelerate security analysis, reduce manual toil in threat detection pipelines, and improve the scalability of security operations
Establish service level objectives and reliability posture for network security systems, including dashboards, alerting, and runbooks to reduce mean time to mitigation during incidents
Mentor other engineers on network security principles, threat modeling methodologies, and secure design patterns, and contribute to recruiting and onboarding programs
Communicate security risk, architectural trade-offs, and remediation strategies clearly to engineering leaders and cross-functional stakeholders through written proposals and design reviews

Minimum Qualifications

8+ years of experience in network security engineering, network infrastructure security, or a closely related security discipline
Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience

Preferred Qualifications

Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
Track record of building network security telemetry pipelines and applying data-driven analysis to prioritize and validate security improvements
Experience designing and implementing security controls for large-scale network environments, including firewalls, access control lists, network segmentation, and traffic inspection systems
Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
Experience defining and operating security controls in software-defined networking or cloud-native network environments at hyperscale
Experience building or operating network security monitoring, anomaly detection, or intrusion detection systems at scale
Experience leading multi-team technical initiatives, including driving cross-functional alignment, managing dependencies, and delivering measurable security outcomes
Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
Experience with network security automation, including programmatic configuration management, policy-as-code frameworks, or security orchestration tooling in large-scale infrastructure environments
Experience conducting threat modeling, vulnerability assessments, or security architecture reviews for network infrastructure components such as routers, switches, load balancers, or BGP/OSPF routing systems
Familiarity with offensive network security techniques such as network penetration testing, protocol fuzzing, or adversarial traffic analysis used to validate defensive controls

$184,000/year to $257,000/year + bonus + equity + benefits
