Network Engineer (Data Center Migration)

New Era Technology is seeking a skilled and motivated Mid-Level Network Engineer to support the planning, execution, and implementation of data center migration projects. The role involves executing network deployment and migration tasks, ensuring network readiness, and coordinating with cross-functional teams for seamless workload migrations.

Responsibilities:

• Execute network deployment and migration tasks associated with data center compute migrations, including pre-migration assessments, cutover activities, and post-migration validation
• Support end-to-end network implementation for compute migration waves, ensuring network readiness at both source and destination data centers
• Serve as a key technical contributor for network-related aspects of assigned migration projects, escalating complex issues to senior engineers as needed
• Coordinate with cross-functional teams (compute, storage and application teams) to ensure seamless migration of workloads with minimal downtime
• Engage with third-party vendors, including telecom carriers and colocation providers, for circuit provisioning, cross-connects, and troubleshooting during migration activities
• Ensure all network changes adhere to established change management processes, security policies, compliance requirements, and best practices
• Develop and maintain network documentation, including migration runbooks, network diagrams, IP allocation records, configuration templates, and post-migration validation checklists
• Participate in migration rehearsals and dry runs, identifying potential risks and contributing to rollback plans

Requirements:

• 5 to 8 years of experience in network engineering, with a meaningful portion focused on data center environments
• Demonstrated experience participating in or supporting data center migrations, consolidations, or large-scale infrastructure moves
• Hands-on experience executing network changes during planned maintenance windows and migration cutovers, including off-hours work as required
• Experience working within structured change management processes
• Proven ability to collaborate with cross-functional technical teams and follow project plans under the direction of senior engineers or project managers
• Experience interacting with third-party vendors and carriers for circuit-related activities
• Core Routing & Switching - Strong hands-on experience configuring, deploying, and troubleshooting enterprise-grade routers and switches (e.g., Nexus, IOSXR and IOSXE platforms)
• BGP Routing - Solid working knowledge of BGP in data center and enterprise environments, including session establishment, route advertisement, and route manipulation
• Network Segmentation - Practical experience configuring and managing VRFs (Virtual Routing and Forwarding) and VLANs to support workload isolation during and after migrations
• Data Center Networking - Familiarity with data center network architectures, including spine-leaf topologies and overlay technologies such as Segment routing and EVPN
• Network Security - Solid understanding of ACLs, firewall rule coordination, and security zone concepts relevant to migration traffic flows
• IP Address Management (IPAM) - Proficient in IP address planning, subnetting, re-addressing, and allocation — particularly in the context of migrating workloads between data centers with differing IP schemes
• Network Monitoring & Troubleshooting - Experience using network monitoring tools (e.g., Probers, Wireshark, SNMP-based tools) for pre- and post-migration health checks and rapid issue resolution
• QoS (Quality of Service) - Working knowledge of QoS policies and traffic prioritization, particularly for ensuring critical application performance during migration windows
• Execution & Accountability: Ability to take ownership of assigned migration tasks and drive them to completion with moderate supervision, proactively flagging risks and blockers
• Organization & Attention to Detail: Highly organized with meticulous attention to detail — critical for tracking migration waves, IP re-addressing, and configuration accuracy
• Communication: Strong verbal and written communication skills; able to provide clear status updates, document migration outcomes, and participate in bridge calls during cutovers
• Problem-Solving: Solid analytical and troubleshooting skills to diagnose and resolve network issues efficiently during time-sensitive migration windows
• Collaboration: Ability to work effectively within a multi-disciplinary migration team (compute, storage, security, applications) and escalate appropriately
• Documentation: Proficient in creating and maintaining comprehensive migration documentation, including network diagrams, runbooks, validation checklists, and post-migration reports
• Adaptability: Comfortable working in dynamic project environments with shifting timelines and priorities; willing to work off-hours during migration cutovers as needed
• Minimum of Bachelors Degree Required
• Network Automation & Scripting: Familiarity with Python, Ansible, or similar tools for automating repetitive migration tasks such as configuration generation, validation checks, and bulk changes
• Load Balancing: Basic experience with load balancers (e.g., Citrix NetScaler) and understanding of VIP migrations
• Segment Routing: Familiarity with Segment Routing technologies (e.g., SR-MPLS and EVPN) as applicable to data center interconnects
• Cisco Certifications (e.g., CCNA, CCNP Enterprise)
• Aruba Certifications (e.g., ACMA, ACMP)
