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.
