Principal Security Architect - Zero Trust & Network Segmentation

Our client is seeking a Security Architecture leader to modernize their internal security architecture, shifting from periodic reviews to an engineering-driven approach that keeps pace with AI-accelerated threats. Responsibilities Assess, redesign, and reengineer internal network architecture across security domains, delivering remediation roadmaps and risk reduction strategies. Lead internal segmentation, micro-segmentation, Zero Trust, and enclave hardening initiatives to limit lateral movement and reduce incident blast radius. Perform detailed analysis of high-risk network pathways, documenting remediation options and phased implementation plans. Evaluate and strengthen CI/CD pipelines and Infrastructure-as-Code (IaC) environments, embedding security directly into delivery workflows. Own architectural governance throughout the change lifecycle, ensuring ongoing security alignment and design integrity. Map vulnerabilities and findings to adversary TTPs, enabling proactive detection and response capabilities. Qualifications Deep expertise in Security Architecture, Network Security, Zero Trust, and Segmentation. Experience with cloud and hybrid environments, CI/CD security, and Infrastructure-as-Code platforms. Strong understanding of threat modeling, detection engineering, and adversary TTP frameworks (e.g., MITRE ATT&CK). Proven ability to lead large-scale security transformation and architecture modernization initiatives. #J-18808-Ljbffr The Judge Group
