• Experience in network engineering, network architecture, telecommunications engineering, or a related technical discipline.
• Demonstrated experience designing and architecting complex WAN, LAN, SD-WAN, transport, and enterprise network solutions.
• Strong knowledge of IP networking, routing protocols, network segmentation, resiliency, high availability, traffic engineering, and network performance.
• Hands‑on experience designing and integrating SD‑WAN architectures, including underlay and overlay networks, routing, policies, orchestration, and secure connectivity.
• Experience developing and reviewing network architectures, high‑level and detailed designs, configurations, engineering standards, and technical documentation.
• Demonstrated experience integrating network solutions across multiple technology platforms, service providers, OEMs, and engineering disciplines.
• Experience with network capacity planning, performance analysis, troubleshooting, and optimization in large‑scale environments.
• Strong understanding of network security principles and the integration of security requirements into enterprise network architectures.
• Ability to evaluate complex technical alternatives and provide engineering recommendations based on performance, resiliency, scalability, security, interoperability, and lifecycle requirements.
• Strong communication skills with the ability to explain complex network architectures and technical decisions to engineering teams, program leadership, customers, and other stakeholders.

Responsibilities

• Define and evolve end-to-end network architectures, engineering standards, and technology roadmaps across WAN, LAN, transport, cloud, and software-defined networking environments.
• Architect and integrate SD-WAN solutions, including overlays, underlays, routing, segmentation, policy, orchestration, and secure connectivity.
• Translate customer, operational, and technical requirements into network architecture, engineering requirements, interface definitions, and implementation strategies.
• Support the Chief Engineer in establishing network technical direction, engineering standards, architectural principles, and design approaches.
• Develop standardized network designs, configurations, engineering patterns, and implementation approaches while accommodating site-specific operational and technical requirements.
• Engineer highly available and resilient network solutions addressing redundancy, diversity, failover, performance, capacity, scalability, and recoverability.
• Evaluate network architecture alternatives and conduct technical trade studies involving performance, resiliency, security, interoperability, cost, and lifecycle considerations.
• Develop network migration and transition strategies that minimize operational risk and support modernization of existing infrastructure.
• Provide technical oversight through high-level and detailed design, integration, test, implementation, migration, and transition to operations.
• Collaborate with cybersecurity teams to incorporate network security, segmentation, access control, encryption, and applicable security requirements into solution designs.
• Partner with systems, cloud, transport, infrastructure, operations, and test engineering teams to ensure end-to-end interoperability and design integrity.
• Establish network capacity and performance requirements and support performance analysis, optimization, and troubleshooting.
• Review network designs, configurations, engineering documentation, interface definitions, test procedures, and vendor/OEM solutions for technical completeness and architectural alignment.
• Provide senior technical expertise during network implementation, troubleshooting, performance degradation, and resolution of complex incidents and engineering issues.
• Evaluate emerging networking technologies, product lifecycle considerations, capacity demands, and technology obsolescence to support long-term network modernization.
• Partner with test and evaluation teams to ensure all technical solutions are fully tested, verified, and validated against applicable system, design, performance, interface, security, and operational requirements prior to deployment or operational acceptance.
• Support execution of all applicable Contractor Master Test Plan (CMTP) activities, including test planning, readiness reviews, requirements traceability, test procedure development, defect resolution, regression testing, results analysis, documentation, and closure of technical test findings.
