Job requirements

• 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.
