You will work across data center, campus, WAN, security, routing, switching, and connectivity technologies to build scalable, resilient, secure, and highly available network solutions. You will translate business and technical requirements into network architectures and detailed engineering designs, develop reusable implementation patterns and standards, perform technology evaluation and certification, automate network configuration and validation, and troubleshoot complex network and connectivity issues. This role requires strong hands-on networking expertise combined with an engineering mindset focused on automation, repeatability, observability, resiliency, performance, and continuous improvement.\nWhat you'll do\nDesign and engineer enterprise network solutions spanning data center, WAN, LAN, routing, switching, segmentation, secure connectivity, resiliency, and high availability.\nDevelop high-level designs (HLDs), low-level designs (LLDs), engineering standards, implementation patterns, test plans, operating procedures, and technical decision records.\nTranslate infrastructure, application, security, resiliency, and performance requirements into scalable network architectures and detailed technical solutions.\nEngineer Layer 2 and Layer 3 networking technologies including VLANs, VRFs, BGP, OSPF, STP, gateway redundancy, route policy, segmentation, and traffic engineering.\nDesign and support modern data center networking technologies including Cisco Nexus/NX-OS, VXLAN/EVPN fabrics, data center interconnect, and highly available network architectures.\nEngineer secure connectivity solutions incorporating technologies such as IPSec and SD-WAN.\nDevelop and execute engineering validation and certification plans for new network technologies, software releases, hardware platforms, features, architectures, and configuration changes.\nTroubleshoot complex network and application-connectivity problems using packet analysis, routing and forwarding analysis, traffic-flow analysis, telemetry, logs, and network diagnostic tools.\nAnalyze network performance including latency, packet loss, throughput, congestion, path characteristics, and application traffic behavior, and develop engineering recommendations to improve performance and resiliency.\nUse network observability, telemetry, flow analytics, and monitoring platforms to understand network health, traffic behavior, capacity, availability, and performance.\nDevelop and maintain network automation and Infrastructure as Code (IaC) capabilities using scripting, APIs, structured data, source control, automated testing, and configuration-management technologies.\nIntegrate network engineering workflows with Git-based development practices, CI/CD pipelines, automated validation, and source-of-truth systems where appropriate.\nDevelop reusable network standards, configuration models, automation components, validation tests, and engineering patterns to improve consistency and reduce implementation risk.\nEvaluate network technologies, platforms, hardware, software, and architectures based on scalability, resiliency, security, automation capabilities, supportability, performance, operational complexity, and lifecycle requirements.\nParticipate in proof-of-concept, lab validation, certification, production-readiness, and lifecycle-management activities for network technologies.\nPartner with infrastructure, security, application, architecture, operations, and engineering teams throughout the solution lifecycle, from requirements and design through implementation, validation, production support, and continuous improvement.\nProvide technical leadership during complex implementations and incidents, including root-cause analysis, corrective actions, and identification of opportunities for engineering or automation improvements.\nMaintain network architecture, engineering, configuration, and operational documentation to ensure solutions are supportable, repeatable, and operationally sustainable.\nExperience you'll need to have\n5+ years of progressively responsible experience in network engineering, network infrastructure engineering, or a related technical field.\nDemonstrated experience designing, implementing, troubleshooting, and supporting complex enterprise network environments.\nStrong knowledge of Layer 2 and Layer 3 networking concepts and protocols, including Ethernet, VLANs, STP, VRFs, BGP, OSPF, route policy, gateway redundancy, and IP networking.\nExperience with enterprise routing and switching technologies such as Cisco Catalyst, Cisco Nexus/NX-OS, Cisco IOS-XE/IOS-XR, or comparable enterprise and service-provider networking platforms.\nExperience with data center networking technologies such as VXLAN/EVPN, leaf-spine architectures, segmentation, data center interconnect, and high-availability design.\nExperience engineering or supporting secure network connectivity, including firewalls, ACLs, network segmentation, NAT, VPN technologies, and related security controls.\nDemonstrated ability to troubleshoot complex problems involving routing, forwarding, packet flow, latency, packet loss, throughput, application connectivity, and network performance.\nExperience using network troubleshooting and observability technologies such as packet capture, traffic-flow analysis, telemetry, logging, monitoring, and performance-analysis tools.\nExperience with network automation, scripting, APIs, configuration management, or Infrastructure as Code.\nFamiliarity with technologies and practices such as Python, Ansible, Terraform, YAML/JSON, REST APIs, Git, CI/CD pipelines, automated testing, and source-of-truth platforms is preferred.\nExperience developing technical documentation such as HLDs, LLDs, engineering standards, implementation procedures, test plans, and operational documentation.\nExperience evaluating or certifying network hardware, software, features, or architectures through lab testing, proof-of-concept activities, or structured engineering validation.\nBachelor's degree in Computer Science, Information Technology, Computer Engineering, Network Engineering, or a directly related field, or an equivalent combination of education and relevant professional experience.\nImportant information about this role:\nThis is a fully onsite position, Monday through Friday.
