• Operations & Troubleshooting: Provide Tier 3/4 escalation support, conducting deep-packet inspection and root cause analysis (RCA) for complex outages.
• Routing & Switching: Manage and optimize advanced routing protocols including BGP, OSPF, and ISIS, specifically focusing on traffic engineering and internet peering.
• Carrier Grade Technologies: Implement and manage carrier-grade NAT (CGNAT) for IPv4/IPv6 transition, AAA/RADIUS infrastructure, and high-capacity wireless/mobility cores.
• Performance Optimization: Maximize network performance through continuous monitoring and capacity planning to handle high-traffic volumes.
• Automation: Develop and implement automation scripts using Python, Ansible, or Terraform to streamline configuration, provisioning, and MOP (Method of Procedure) execution.
• Security & Compliance: Ensure compliance with security standards (e.g., ISO27001, PCI-DSS) and implement network-level security, such as DDoS protection and lawful intercept.
• Documentation: Create and maintain detailed network diagrams, MOPs, and technical documentation.

Qualifications

Required Qualifications & Experience:

• Masters Degree in Network Engineering or related field + 8 years experience or Bachelors Degree in Network Engineering or related field + 10 years experience. 5+ years experience with provisioning 1/carrier class networks.
