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
