DWDM-IP Engineer

Responsibilities

• Design, deploy, and operate DWDM-based transport networks across long-haul and metro environments
• Perform wavelength provisioning, optical power tuning, and amplification design (EDFA/Raman) to ensure optimal link performance
• Troubleshoot cross-layer issues spanning optical transport and IP/MPLS networks, including packet loss, latency, and signal degradation
• Execute fiber characterization and fault isolation using OTDR, OSA, and BERT tools across various span distances
• Develop and maintain Python-based automation for optical health checks, telemetry ingestion, and inventory synchronization
• Participate in network expansions and hardware deployments, including on-site support for critical rollouts and audits
• Collaborate with IP engineering teams to ensure alignment between optical transport and routing layers
• Drive root cause analysis and implement preventive measures to improve fleet-wide reliability and performance

Requirements

• Strong expertise in DWDM systems, including wavelength routing, optical amplification (EDFA/Raman), and dispersion management in long-haul networks
• Solid understanding of IP/MPLS fundamentals, including routing protocols such as BGP, OSPF, or IS-IS, and MPLS signaling
• Hands-on experience with production optical platforms such as Ciena (6500/Waveserver), Infinera, or ADVA
• Proficiency in Python for automation of operational workflows and network validation tasks
• Experience using optical diagnostic tools (OTDR, OSA, BERT) for fiber analysis and troubleshooting
• Ability to debug packet-over-optical issues across layers with precision and speed

Qualifications

• Willingness to travel to data center and network sites across the US/EU for deployments and audits

Skills

• Linux-based network management systems and streaming telemetry for optical monitoring
• Experience with Segment Routing (SR-MPLS or SRv6) and its interaction with optical transport performance
