The posting

Role

We are seeking a highly skilled Certified DWDM Engineer to join our optical transport team. In this role, you will be responsible for the end-to-end lifecycle—design, deployment, and optimization—of our high-capacity Dense Wavelength Division Multiplexing (DWDM) networks.

As a "Certified" specialist, you are expected to bring verified expertise in industry-leading platforms (such as Ciena, Nokia, or Cisco) to ensure our fiber-optic backbone operates with maximum spectral efficiency and 99.999% reliability.

Key Responsibilities

  1. Network Design & Planning
  • Optical Path Engineering: Conduct link budget analysis, OSNR (Optical Signal-to-Noise Ratio) calculations, and chromatic dispersion compensation planning.
  • Capacity Management: Design wavelength allocation maps and manage the growth of C-band and L-band spectrum to meet increasing data demands.
  • Architecture Design: Develop resilient network topologies, including ring protection (SNCP), mesh restoration, and ROADM (Reconfigurable Optical Add-Drop Multiplexer) configurations.
  1. Implementation & Integration
  • Commissioning: Lead the physical installation, power-up, and software configuration of DWDM shelves, transponders, amplifiers (EDFAs/Raman), and multiplexers.
  • Vendor Coordination: Work closely with hardware vendors to integrate new-generation coherent optics (e.g., 400G/800G+ wavelengths) into existing legacy fiber plants.
  • Circuit Provisioning: Manage the end-to-end provisioning of high-bandwidth services (Ethernet, OTN, Fibre Channel) across the optical transport layer.
  1. Maintenance & Troubleshooting
  • Advanced Diagnostics: Utilize OTDR (Optical Time-Domain Reflectometer), OSA (Optical Spectrum Analyzer), and BERT (Bit Error Rate Test) equipment to localize fiber faults and signal degradation.
  • NOC Support: Act as the Tier 3 escalation point for complex optical layer incidents, performing deep-dive root cause analysis on "flapping" links or high Pre-FEC BER issues.
  • Performance Tuning: Monitor and optimize optical power levels and gain tilt across long-haul spans to maintain signal integrity.

Required Skills & Experience

  • Bachelor’s degree in Electrical Engineering, Telecommunications, or a related technical field.
  • Deep understanding of ITU-T G.709 (OTN) standards, WDM physics, and fiber types (G.652, G.655).
  • Proficiency with Network Management Systems (NMS) and SDN controllers for optical automation.
  • Experience using optical modeling software (e.g., Ciena OnePlanner, Nokia 1830 EPT, or VPIphotonics).

Professional Certifications (Preferred)

  • Ciena: Optical Communications Professional (OC-P) or Consultant (OC-C).
  • Nokia: Certified Optical Network Professional (ONP).
  • Cisco: CCNP Optical or specialized Cisco Transport certificates.
  • General: OTT Certified Optical Network Engineer (CONE).

The Ideal Candidate

You are a "fiber-first" engineer who thrives on the physics of light. You understand that a single fiber break can impact terabits of data, and you possess the meticulous attention to detail required to manage the invisible infrastructure that powers the modern internet.

Industry Insight 2026: Preference will be given to candidates with experience in 400ZR/ZR+ pluggable optics and SDN-based optical grooming.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
