Responsibilities:

• Architecture & Design: Design, implement, and maintain high-performance, scalable, and resilient IP network infrastructure (MPLS, IP/Ethernet)
• 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

• Technical Proficiency (L2-L3): TCP/IP, BGP, OSPF, ISIS, MPLS, IKE, IPSEC, VPNs, and VLANs
• Technical Proficiency (L0-L2): SONET/SDH, FDDI, OTN (ITU-T G.709, OTU4, OTU2)
• Hands-on experience with carrier-grade platforms (e.g., Ciena, Cisco ASR/NCS/Nexus, Juniper MX/Mist, Nokia, or Arista)
• Intermediate to advanced proficiency in Python or Ansible
• Strong Linux CLI skills
• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
• CCNP/CCIE (Service Provider or Routing & Switching) preferred, but not required
• Experience with CGNAT platforms (e.g., F5 BIG-IP, A10 Networks)
• Knowledge of 5G core networking or virtualized platforms (VMware, OpenStack)
• Experience with Fiber transport technologies (DWDM, ROADM, WSS, PON)
