NETWORK SECURITY ARCHITECT

Job Title: Network Security Architect Duration: 1 Year Location: Los Angeles, CA (On Site) Job Summary We are seeking an experienced Network Security Architect to assess, design, review, and enhance enterprise network security architecture. The ideal candidate will have strong expertise in network infrastructure, network security, and secure architecture design. The candidate will be responsible for evaluating existing network architecture, identifying security vulnerabilities and architectural gaps, and developing secure, scalable, and resilient network architecture solutions. The role requires the ability to analyze complex network designs, validate security controls, recommend improvements, and visually represent network architecture through detailed technical diagrams. Key Responsibilities Review, assess, and analyze existing enterprise network architecture, infrastructure, and security designs. Design and develop secure, scalable, and resilient network architecture solutions. Evaluate network topology, routing, switching, firewalls, VPNs, and network segmentation. Identify security vulnerabilities, architectural weaknesses, and potential risks within existing network infrastructure. Develop secure network designs incorporating network segmentation, security zones, Zero Trust principles, and defence-in-depth strategies. Review and validate existing and proposed network architecture to ensure security, scalability, reliability, and compliance with industry best practices. Evaluate network security controls, firewall configurations, access management, and network traffic flows. Recommend appropriate security solutions and architectural improvements to address identified gaps. Develop current-state and future-state network architecture diagrams. Create detailed network topology diagrams, security architecture diagrams, and network traffic flow visualizations. Use architecture visualization tools to communicate complex network designs to technical teams and stakeholders. Collaborate with network engineering, infrastructure, cybersecurity, and other technical teams to develop and validate architecture solutions. Prepare technical documentation, architecture recommendations, and design specifications. Required Technical Skills Extensive experience in enterprise network architecture and network security. Strong understanding of LAN, WAN, TCP/IP, routing, switching, VLANs, and network protocols. Experience with enterprise firewall technologies such as Palo Alto, Cisco, Fortinet, or Check Point. Strong knowledge of network segmentation, DMZ, VPN, IDS/IPS, and secure network connectivity. Experience designing, reviewing, and evaluating secure enterprise network infrastructure. Knowledge of Zero Trust Network Architecture and defense-in-depth security principles. Understanding of network security policies, access controls, and threat mitigation strategies. Experience with network architecture visualization and diagramming tools such as Microsoft Visio, Lucid chart, or Draw.io. Ability to translate complex technical requirements into secure network architecture designs. Preferred Qualifications Experience working with large-scale enterprise network environments. Knowledge of cloud network security architecture (AWS or Azure). Familiarity with cybersecurity frameworks and standards such as NIST, ISO 27001, and CIS Controls. Relevant networking or security certifications such as CCNP Security, CCIE Security, CISSP, or equivalent. Excellent analytical, problem-solving, documentation, and communication skills. Expected Deliverables Assessment and review of existing network architecture. Identification of network security gaps and architectural risks. Recommendations for secure network architecture improvements. Design and validation of proposed secure network architecture. Current-state and future-state network architecture diagrams. Network security design documentation and technical recommendations.
