About the role
Job Summary
We are looking for a Optical Network/DWDM-IP Engineer to own the lifecycle of our optical transport network and its integration with the IP/MPLS core. You will be responsible for operating a hybrid ecosystem of short-haul (DC interconnects), metro, and long-haul DWDM systems. This role requires a "Full-Stack Transport" mindset—where you understand the physics of the fiber, signal modulation and could overview the logic of the ip/MPLS part of network.
Job Responsibilities:
- Hybrid Infrastructure Management: Configure, deploy, and scale multi-vendor DWDM systems (Ciena, Nokia-Infinera, ADVA/Adtran) to support 400G/800G+ coherent interfaces.
- Operational Excellence: Lead the troubleshooting of complex optical-to-IP failures, ensuring minimal MTTR for critical backbone spans and DCI links.
- Network Evolution: Design and test new optical solutions, focusing on Open Line Systems (OLS), disaggregated hardware, and pluggable coherent optics (QSFP-DD/OSFP).
- Automation & Data Integrity: Build and maintain the "Source of Truth" (Netbox-based) for lambdas, channels, and dark fiber assets; participating in automate commissioning via Python/gNMI.
- Strategic Collaboration: Work with Data Center Ops and IP Engineering to align optical capacity with traffic engineering (SR-MPLS) demands.
- Vendor & Asset Management: Manage relationships with dark fiber providers and channel suppliers; monitor performance against SLAs.
We Expect You To
- Deep Optical Expertise: Knowledge of ROADM networks and use-cases, optical amplification (EDFA/Raman), understand Coherent modulation formats and its characteristics in multi span long-haul scenarios.
- IP/MPLS Proficiency: Have an understanding of the IP/MPLS stack (any from BGP/OSPF/IS-IS) to perform initial debugs on packet-over-optical issues.
- Hands-on with Production Platforms: Direct experience with ADVA/Adtran platforms or Ciena /Nokia-Infinera
- Automation Mindset: good to read Python for automating routine of inventory synch
- Diagnostic Precision: Expert use of OTDR, OSA, and BERT equipment for characterization of short, middle, and long-haul fiber spans.
- Mobility: Willingness to travel to key sites in the USA/EU/APAC for critical hardware deployments and complex physical-layer audits.
Preferred Qualifications
- Good in Linux-based network tools and telemetry for optical monitoring.
- Proven track record in network modernization projects (e.g., migrating from 100G to 400G/800G architectures).
- Nice to have Experience with MPLS and its interaction with optical layer performance metrics.
