Experience: 6+ years of relevant network engineering experience preferred Role Overview We are seeking a Data Center Network Engineer with hands-on experience in Cisco Nexus hardware refresh, device replacement, and production network migrations across Cisco ACI and standalone NX-OS environments. The role includes migrating connectivity from legacy Nexus 2000/5000 platforms and existing Nexus 9000 devices to approved target platforms. The engineer will own technical preparation, configuration validation, cutover execution, troubleshooting, and post-migration support. Key Responsibilities Review source and target device inventories, network diagrams, configurations, connectivity, and application dependencies. Assess hardware readiness, including rack space, power, airflow, optics, cable types, port capacity, and software compatibility. Prepare detailed port mappings covering source and destination interfaces, VLANs, port channels, uplinks, and connected endpoints. Translate and validate configurations for target platforms, identifying unsupported features and required design changes. Develop Methods of Procedure (MOPs), migration sequences, pre- and post-checks, rollback plans, and acceptance criteria. Coordinate device installation, cabling, labeling, and console access with Data Center operations and remote-hands teams. Configure and validate target switches, including management access, routing, switching, redundancy, and monitoring. For ACI migrations, support fabric discovery, node registration, interface policies, and access-policy validation according to the approved design. Execute phased cable moves and traffic cutovers within approved maintenance windows. Validate endpoint connectivity, routing adjacencies, interface health, port-channel operation, and application reachability. Troubleshoot migration issues and execute rollback when agreed recovery thresholds are reached. Update inventory, topology diagrams, port mappings, implementation evidence, and change records. Support legacy-device decommissioning after migration acceptance and required approvals. Required Technical Skills Hands-on experience with Cisco Nexus 2000 Fabric Extenders, Nexus 5000, and Nexus 9000 platforms. Strong knowledge of NX-OS and Cisco ACI fundamentals, including APIC, fabric nodes, tenants, bridge domains, EPGs, and contracts. Experience migrating FEX-connected endpoints and assessing differences between existing and target connectivity designs. Strong understanding of VLANs, trunking, STP, LACP, port channels, vPC, VRFs, BGP, and OSPF. Experience troubleshooting optics, speed settings, breakout interfaces, MTU, cabling, and interface errors. Ability to independently prepare migration plans and lead technical cutover activities. Experience working within enterprise change-management and incident-management processes. Preferred Qualifications CCNP Data Center or equivalent practical expertise. Experience supporting large-scale Data Center hardware refresh programs in banking or similarly controlled environments. Familiarity with Ansible or Python for configuration comparison, validation, and evidence collection. Interview Focus Candidates should be prepared to explain a production hardware migration they personally executed, covering port mapping, configuration conversion, dependency identification, cutover sequencing, troubleshooting, rollback decisions, and service validation. Working Expectations Availability for scheduled weekend or overnight maintenance windows, strong coordination with onsite teams, and ownership through post-migration stabilization.
