The Network Architect will work collaboratively with enterprise architects, solution architects, cybersecurity professionals, cloud engineers, systems administrators, application teams, and program leadership. Experience supporting the Transportation Security Administration (TSA), Department of Homeland Security (DHS), or comparable federal environments is highly preferred. Minimum Experience: 5+ years of relevant network engineering, network architecture, infrastructure architecture, or related experience.

Key Responsibilities

Develop current-state and target-state network architectures, designs, diagrams, standards, and technical documentation. Assess existing network infrastructure and identify performance, capacity, resiliency, security, interoperability, and modernization requirements. Translate business, mission, security, and technical requirements into logical and physical network architecture designs. Design and document LAN, WAN, WLAN, VPN, remote-access, internet connectivity, and hybrid/cloud network solutions. Develop network architecture artifacts, including topology diagrams, data-flow diagrams, interface specifications, architecture views, standards, and design documentation. Support network segmentation, routing, switching, load balancing, firewalls, DNS, DHCP, IP addressing, and related infrastructure services. Evaluate network technologies and recommend solutions based on security, performance, scalability, interoperability, cost, maintainability, and lifecycle considerations. Support cloud and hybrid-cloud connectivity and integration between on-premises and cloud environments. Incorporate cybersecurity requirements, Zero Trust principles, access controls, encryption, network segmentation, and applicable federal security requirements into architecture designs. Participate in architecture reviews, engineering reviews, technical design reviews, requirements sessions, and governance activities. Identify architecture dependencies, risks, constraints, assumptions, interfaces, and integration requirements. Collaborate with engineering, implementation, operations, cybersecurity, and enterprise architecture teams to ensure architectures are implementable and operationally supportable. Develop technology roadmaps and recommendations for network modernization, lifecycle management, technical debt reduction, and future-state capabilities. Support development of technical requirements, acquisition documentation, Statements of Work, technical evaluations, and vendor assessments when required. Develop and maintain architecture documentation in accordance with applicable TSA/DHS enterprise architecture, cybersecurity, and technology governance processes and standards when supporting TSA programs.

Required Qualifications

Demonstrated experience designing or supporting enterprise-scale network infrastructure. Strong knowledge of TCP/IP, IPv4/IPv6, DNS, DHCP, VLANs, VPNs, routing, switching, firewalls, network segmentation, and related network technologies. Experience developing network architecture diagrams and technical documentation using Microsoft Visio, Lucidchart, or comparable tools. Understanding of network security and secure network architecture principles. Experience translating technical and operational requirements into network designs. Understanding of high availability, redundancy, disaster recovery, scalability, capacity, and network performance considerations. Familiarity with cloud networking and hybrid network architectures. Ability to communicate complex technical concepts to technical and nontechnical stakeholders. Strong analytical, problem-solving, documentation, and collaboration skills. TSA/DHS Experience — Highly Preferred Candidates with prior TSA or DHS experience should receive additional consideration, particularly experience involving: TSA or DHS enterprise architecture, infrastructure architecture, network engineering, or technology modernization. Supporting TSA headquarters, data center, field, airport, or other mission-supporting technology environments. Working within federal enterprise architecture and technology governance processes. DHS/TSA cybersecurity, information assurance, Zero Trust, or security architecture requirements. Federal network modernization, cloud migration, infrastructure transformation, or technology lifecycle initiatives. Developing architecture artifacts, technical standards, engineering documentation, or architecture recommendations for TSA/DHS stakeholders. Working within TSA/DHS technical review, configuration management, change management, or governance processes. Coordination across federal employees, contractors, engineering teams, cybersecurity organizations, and technology vendors. Familiarity with TSA credentialing/PIV and suitability processes is beneficial for candidates who will require access to TSA facilities or systems. Preferred Technical Qualifications Experience with technologies or environments involving Cisco, Palo Alto Networks, Fortinet, Juniper, SD-WAN, software-defined networking, AWS, Microsoft Azure, network automation, cloud connectivity, and Zero Trust Architecture is preferred. Relevant certifications such as Cisco CCNA/CCNP, CompTIA Network+, CompTIA Security+, AWS, Microsoft Azure, or equivalent are preferred unless specific certifications are required by the applicable contract.
