DWDM / SONET Network Engineer

Accountabilities

• • Configure, monitor, troubleshoot, and manage optical transport equipment, using TL1 and command-line interfaces where applicable.
  • Provision, activate, test, and validate DWDM, SONET/SDH, and OTN services and circuits with a focus on accuracy and service reliability.
  • Operate network management systems to support topology management, performance monitoring, fault management, and circuit administration.
  • Conduct detailed end-to-end audits and tracing of optical services and circuits to verify connectivity, configuration, and operational status.
  • Execute network upgrades, migrations, and cutovers while minimizing downtime and maintaining service continuity.
  • Support circuit provisioning and migration activities across multi-vendor optical transport environments.
  • Create, maintain, and update technical documentation covering circuits, equipment configurations, service changes, and migration plans.
  • Collaborate with internal engineering and operations teams during maintenance windows, deployments, upgrades, and other network activities.
  • Troubleshoot optical transport issues and communicate findings, corrective actions, and operational recommendations clearly to relevant stakeholders.
  • Apply strong attention to detail and structured processes to ensure network configurations, service records, and operational documentation remain accurate.

  Requirements
