DWDM-IP Engineer

The role:
We are looking for an Optical & IP Transport Engineer (DWDM/IP) to own the design, deployment, and operation of large-scale optical transport networks supporting high-density, latency-sensitive infrastructure. You will work at the intersection of DWDM systems and IP/MPLS layers, ensuring reliable packet delivery across long-haul and metro fiber networks.

This role requires deep understanding of optical physics and packet transport, with hands-on responsibility for production networks. You will be involved in end-to-end lifecycle management—from planning and turn-up to troubleshooting complex cross-layer issues impacting performance and availability. The position demands strong diagnostic capabilities, automation-driven operations, and the ability to operate close to the hardware in mission-critical environments.

Your responsibilities will include:

• 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

• Work directly with production platforms (Ciena, Infinera, ADVA) for provisioning, upgrades, and incident resolution

• 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

What we expect you to have:

• 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

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

It will be an added bonus if you have:

• Experience with Linux-based network management systems and streaming telemetry for optical monitoring

• Background in network modernization projects, including migrations from 100G to 400G/800G architectures

• Familiarity with Segment Routing (SR-MPLS or SRv6) and its interaction with optical transport performance

Working conditions:

• Remote role based in the United States

• Travel required for on-site deployments and physical-layer audits

Key employee benefits:

• Comprehensive health insurance (medical, dental, vision)

• 401(k) plan with company contribution

• Generous paid time off and sick leave

• Paid parental leave

• Flexible working hours

• Professional development support

Compensation:

• Base salary: $125,000 – $180,000 per year

• Performance-based bonus included
