SAIC is seeking a seasoned Sr. Network Engineers to join our Network Team. 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.
Key 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.
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 carrier class networks.
Required Skills & Experience
Experience: 5 -15+ years in network engineering, specifically within a service provider, ISP, or carrier-grade data center environment.
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)
Hardware Expertise: Hands-on experience with carrier-grade platforms (e.g., Ciena, Cisco ASR/NCS/Nexus, Juniper MX/Mist, Nokia, or Arista).
Automation/Scripting: Intermediate to advanced proficiency in Python or Ansible.
Linux/Unix: Strong Linux CLI skills.
Education: Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
Certifications: CCNP/CCIE (Service Provider or Routing & Switching) preferred, but no required
Preferred Qualifications
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).
