Sr. Network Engineer

Position: Sr. Network Engineer

Location: Remote

Hiring Mode: 6 Months Contract

Job Description:

The Network Engineer is responsible for planning, executing, and validating the migration of Ethernet and Dedicated Internet Access (DIA) customer circuits from legacy networks and devices to a new Nokia-based MPLS network. This role performs detailed technical analysis, circuit design updates, live network migrations, and post-cutover validation while ensuring minimal customer impact and adherence to change management standards.

The engineer works closely with project managers, field teams, NOCs, and carrier partners to deliver reliable, scalable, and fully documented customer circuit migrations.

Key Responsibilities:

Network Engineering & Migration Execution

• Perform customer circuit migrations for Ethernet and DIA services from legacy platforms to new Nokia network
• Execute live maintenance windows, circuit provisioning, including turn-up, cutover, rollback, and post-migration validation
• Configure, test, and troubleshoot Nokia MPLS routers and related transport equipment
• Validate service performance post-migration (latency, packet loss, throughput, BFD, LSP status, etc.)

Design, Documentation & Systems Updates

• Update circuit designs, logical diagrams, and service paths to reflect new MPLS architecture
• Maintain accurate records in network inventory, provisioning, and design systems (e.g., circuit databases, NMS, OSS tools)
• Create and update Methods of Procedure (MOPs), as-built documentation, and migration runbooks
• Ensure circuit IDs, port assignments, VLANs, IP addressing, and routing details are correctly captured

Legacy Network Decommissioning

• Identify and validate legacy circuit dependencies prior to migration
• Support decommissioning of legacy network elements and services post-migration
• Coordinate cleanup of obsolete configurations and reclaim ports and resources Cross

Functional Coordination

• Collaborate with project managers to support migration planning and scheduling
• Work with NOC and field operations during live cutovers and troubleshooting events
• Engage carriers and vendors as needed for circuit readiness, testing, and issue resolution
• Provide technical guidance and escalation support during complex migrations Change,

Risk & Quality Management

• Follow established change management and maintenance window procedures
• Develop rollback plans and execute recovery actions when required
• Proactively identify migration risks and service-impact concerns
• Participate in post-migration reviews and continuous improvement initiatives

Required Qualifications

• 5+ years of experience in telecommunications or service-provider network engineering
• Hands-on experience migrating Ethernet and DIA circuits in a carrier network
• Strong working knowledge of MPLS fundamentals (LSPs, VRFs, QoS, L2/L3 VPNs)
• Experience with Nokia (Alcatel-Lucent) routers and operating systems (SR OS preferred)
• Proficiency in updating circuit design, inventory, and provisioning systems
• Ability to execute live production changes in high-availability networks

Preferred Qualifications

• Experience migrating from legacy platforms (TDM, legacy Ethernet, older IP/MPLS gear)
• Familiarity with Nokia service routers (e.g., 7750 SR, 7250 IXR)
• Knowledge of OSS/BSS tools such as INAM, CND, Granite, or similar inventory systems
• Understanding of carrier Ethernet standards (MEF)
• Experience supporting after-hours and weekend maintenance windows

Key Skills

• Ethernet and DIA service delivery
• Nokia MPLS configuration and troubleshooting
• Circuit design and documentation accuracy
• OSS/NMS systems proficiency
• Change management and risk mitigation
• Strong troubleshooting and root-cause analysis
• Clear technical communication
