Optical Network Development Engineer , Capacity Restoration Team

Optical Restoration & Troubleshooting - Troubleshoot and restore out-of-service optical capacity across DWDM backbone and metro networks, including coherent optics, amplifiers (EDFA/Raman), ROADMs, and mux/demux components. - Diagnose optical impairments: fiber attenuation, connector/splice loss, chromatic dispersion, PMD, OSNR degradation, and nonlinear effects (FWM, SPM, XPM, SBS). - Execute and interpret OTDR traces, optical spectrum analyzer (OSA) readings, and power meter measurements to isolate physical-layer faults. - Develop link test plans and structured diagnostic output for optical circuits that enable system-guided troubleshooting. - Coordinate with fiber operations and vendor teams for fiber splicing, connec BASIC QUALIFICATIONS - Bachelor's degree in Electrical Engineering, Photonics, Telecommunications, Computer Science, or equivalent experience. - 1+ years of experience in optical network engineering, DWDM operations, or optical transport systems. - Understanding of DWDM technology fundamentals: wavelength multiplexing, optical amplification (EDFA, Raman), coherent detection, and modulation formats. - Knowledge of fiber optic fundamentals: single-mode fiber types (G.652, G.654, G.655), attenuation, chromatic dispersion, and PMD. - Familiarity with optical test and measurement: OTDR, OSA, power meters, and light sources. - Experience with at least one programming or scripting language (Python preferred). - Underst PREFERRED QUALIFICATIONS - Experience with coherent optic technologies: DP-QPSK, 16QAM, and higher-order modulation formats at 100G/200G/400G+ line rates. - Experience with optical networking vendor platforms (e.g., Ciena, Infinera, Nokia, ADVA) including provisioning, alarm management, and firmware operations. - Knowledge of OSNR analysis, optical link budgets, and span engineering for long-haul and metro DWDM systems. - Understanding of FEC mechanisms (SD-FEC, HD-FEC) and their role in optical system margin management
