• Deploy and maintain DWDM open line systems for data center interconnects, covering wavelength provisioning, optical power checks, alarm monitoring and capacity growth.
• Troubleshoot faults across packet and optical layers, including route instability, packet loss, congestion, fiber loss and degraded optical performance, and coordinate fixes with carriers and colocation providers.
• Automate provisioning, configuration validation, backups and operational checks using Python, Ansible or similar tools, and improve telemetry and alerting.
• Carry out planned maintenance with documented validation and rollback steps, and take part in incident response and root cause analysis.

• Hands-on experience with carrier-grade PTX-class routers and Junos OS or Junos Evolved, including routing policy and upgrades.
• Strong working knowledge of IPv4/IPv6, BGP, internet routing, peering and transit, and failure detection and convergence.
