Responsibilities:

  • Design, rollout, and optimisation of large DWDM and optical transport networks
  • IP network design and operation at scale, supporting backbone and data centre connectivity
  • Optical planning, modelling, and capacity forecasting using industry-standard tools
  • Ownership of network stability through advanced troubleshooting and root-cause analysis
  • Working closely with global engineering teams to evolve network architectures and standards
  • Contributing to automation, operational excellence, and continuous improvement initiatives


Experience Needed:

  • 3+ years’ industry experience in large-scale network engineering
  • Extensive hands-on experience with DWDM networks and optical transport technologies
  • Strong background in optical planning and modelling tools
