You will be responsible for the architecture, design, deployment, and optimization of our high-traffic, carrier-grade network infrastructure. The ideal candidate has deep, hands-on experience maintaining five-nines (99.999%) availability in a dedicated infrastructure (utilizing dark fiber, wavelength services), service provider, and/or large-scale data center. You will lead complex troubleshooting, ensure robust security, and drive network modernization, including advanced L0 optimization, IPv4/IPv6 transition and SDN (L0-L3) automation physical transport, data link, and network layers simultaneously. This position is remote with travel.\nKey Responsibilities:\nArchitecture & Design: Design, implement, and maintain high-performance, scalable, and resilient IP network infrastructure (MPLS, IP/Ethernet).\nOperations & Troubleshooting: Provide Tier 3/4 escalation support, conducting deep-packet inspection and root cause analysis (RCA) for complex outages.\nRouting & Switching: Manage and optimize advanced routing protocols including BGP, OSPF, and ISIS, specifically focusing on traffic engineering and internet peering.\nCarrier Grade Technologies: Implement and manage carrier-grade NAT (CGNAT) for IPv4/IPv6 transition, AAA/RADIUS infrastructure, and high-capacity wireless/mobility cores.\nPerformance Optimization: Maximize network performance through continuous monitoring and capacity planning to handle high-traffic volumes.\nAutomation: Develop and implement automation scripts using Python, Ansible, or Terraform to streamline configuration, provisioning, and MOP (Method of Procedure) execution.\nSecurity & Compliance: Ensure compliance with security standards (e.g., ISO27001, PCI-DSS) and implement network-level security, such as DDoS protection and lawful intercept.\nDocumentation: Create and maintain detailed network diagrams, MOPs, and technical documentation.\n Required Qualifications & Experience:\nMasters 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.\nRequired Skills & Experience\nU.S. citizenship and an active Top-Secret clearance, with the ability to obtain a TS/SCI.\nExperience: 5 -15+ years in network engineering, specifically within a service provider, ISP, or carrier-grade data center environment.\nTechnical Proficiency (L2-L3): TCP/IP, BGP, OSPF, ISIS, MPLS, IKE, IPSEC, VPNs, and VLANs.\nTechnical Proficiency (L0-L2): SONET/SDH,FDDI, OTN (ITU-T G.709, OTU4, OTU2).\nHardware Expertise: Hands-on experience with carrier-grade platforms (e.g., Ciena, Cisco ASR/NCS/Nexus, Juniper MX/Mist, Nokia, or Arista).\nAutomation/Scripting: Intermediate to advanced proficiency in Python or Ansible.\nLinux/Unix: Strong Linux CLI skills.\nEducation: Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.\nCertifications: CCNP/CCIE (Service Provider or Routing & Switching) preferred, but no required.\nPreferred Qualifications\nExperience with CGNAT platforms (e.g., F5 BIG-IP, A10 Networks).\nKnowledge of 5G core networking or virtualized platforms (VMware, OpenStack).\nExperience with Fiber transport technologies (DWDM, ROADM, WSS, PON).\nWhy Join Us\nWork on one of the largest infrastructure deployments in the region.\nDirect influence on network architecture and modernization projects.\nCompetitive salary and comprehensive benefits package, including 401(k) matching.","description_format":"text","description_chars":3563,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
