Job Description

Why work at Nebius
Nebius is leading a new era in cloud computing to serve the global AI economy. We create the tools and resources our customers need to solve real-world challenges and transform industries, without massive infrastructure costs or the need to build large in-house AI/ML teams. Our employees work at the cutting edge of AI cloud infrastructure alongside some of the most experienced and innovative leaders and engineers in the field.

Where we work
Headquartered in Amsterdam and listed on Nasdaq, Nebius has a global footprint with R&D hubs across Europe, North America, and Israel. The team of over 1400 employees includes more than 400 highly skilled engineers with deep expertise across hardware and software engineering, as well as an in-house AI R&D team.

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 perfo
