This role focuses on IP routing, BGP, data center networking, and network architecture, including the core data center fabric and connectivity. The engineer owns work across the engineering lifecycle, from design and implementation through troubleshooting, documentation, standards, and lifecycle management. The ideal candidate brings deep routing expertise, strong troubleshooting skills, and the ability to independently develop solutions for complex network problems. The team also supports firewalls and application delivery infrastructure. As part of a small engineering team, this role carries broad technical ownership and provides opportunities to influence engineering standards, technical direction, and network architecture. ### What You'll Do Serve as a technical resource for IP routing, BGP, data center networking, and network architecture. Design and support routing for the LTE and 5G packet cores, internet edge, and data center core. Own engineering efforts from design and lab validation through implementation, testing, documentation, and operational handoff. Troubleshoot complex routing, forwarding, convergence, asymmetric path, and application connectivity issues. Perform packet and protocol level analysis using routing tables, forwarding state, packet captures, logs, and telemetry. Develop network standards, reusable designs, peer-review practices, and implementation procedures. Evaluate new technologies through research, lab testing, and proof-of-concept deployments. Work with vendors on architecture, implementation, technical escalations, and product issues. Improve reliability and consistency through automation and repeatable engineering practices. Provide technical leadership through design ownership, collaboration, mentoring, and knowledge sharing. ### What We're Looking For Must Have Progressive hands on experience designing, implementing, and troubleshooting complex production IP networks. Deep practical knowledge of BGP, including path selection, routing policy, communities, route filtering and advertisement, redundancy, convergence, and traffic engineering. Strong networking fundamentals, including VRFs, ECMP, BFD, IPv4, Ethernet, VLANs, TCP/UDP, MTU, and packet forwarding behavior. Strong packet level troubleshooting skills, including the ability to analyze traffic flows and protocol exchanges to identify routing, transport, application-connectivity, and network-security issues. Experience correlating packet behavior with routing state, forwarding paths, firewall policy, NAT, and expected application flows. Ability to independently design and implement solutions rather than only execute predefined configurations. Ability to evaluate designs for resiliency, scalability, operational complexity, and risk. Strong technical communication, documentation, and collaboration skills. Ability to work effectively within a small team where engineers have broad technical ownership. Strongly Preferred Experience with several of the following is highly desirable: BGP EVPN and VXLAN Layer 3 leaf-spine architectures Advanced BGP routing policy design Arista EOS VRF based segmentation Internet edge or external BGP connectivity Highly available data center or service provider style architectures Network automation using Python, Ansible, APIs, or infrastructure-as-code practices Configuration management, source control, telemetry, or automated network validation Helpful Experience Experience in these areas is a plus, but is not required: Advanced knowledge of next-generation and application aware firewalls Firewall routing, NAT, VPNs, segmentation, and stateful inspection VMware NSX-T F5 LTM and WIP LTE, 5G SA, or mobile packet core networking NetScout for network analytics and visibility Network security and cybersecurity best practices Prior LTE or telecommunications experience is preferred but not required. ### Education and Experience 5+ years of progressive network engineering experience, or equivalent demonstrated expertise with complex production networks. Bachelor's degree in engineering, computer science, or a related technical discipline is strongly preferred. Professional networking certifications such as CCNP, CCIE, or advanced Arista ACE certifications are a plus. ## At a glance - Posted by the employer: Oct 26, 2026 - First seen by OpenNash: Nov 1, 2026 - Last checked: Nov 1, 2026 - Listed for: 6 days - Location: Birmingham, AL, United States - Employment type: Full-time[Apply on Southern Company’s careers site →](https://emje.fa.us6.oraclecloud.com/hcmUI/CandidateExperience/en/sites/CX_1001/job/21199) ## Hiring at Southern Company - Open jobs: 78 - New in the last 7 days: After two weekly collections - Tracked since: Aug 21, 2026 [All Southern Company jobs](https://jobs.opennash.com/companies/southern-company/) · [Weekly hiring report](/reports/hiring/) ## More jobs at Southern Company ### [AI Engineer](https://jobs.opennash.com/companies/southern-company/jobs/e75d2918dddaa6db2f95/) Birmingham, AL, United States ### [BWR Nuclear Fuel and Analysis – Nuclear Engineer Or Analyst](https://jobs.opennash.com/companies/southern-company/jobs/f0413d9f21d3a544b28e/) Birmingham, AL, United States ### [Engineer, Load & Generation Siting – Transmission Expansion Planning](https://jobs.opennash.com/companies/southern-company/jobs/dcdb365bbc7da3f6147a/) Birmingham, AL, United States ### [Associate General Counsel- Birmingham](https://jobs.opennash.com/companies/southern-company/jobs/222fd935101c4bb495ce/) Birmingham, AL, United States ### [Crisis Communications Specialist](https://jobs.opennash.com/companies/southern-company/jobs/d763d3e1d916c841b066/) Birmingham, AL, United States ## Similar jobs at other companies ### [Principal Software Engineer, Core Infrastructure - OCI Networking](https://jobs.opennash.com/companies/oracle/jobs/84e009c75d7e0e6447fb/) Oracle · United States ### [Senior Core Infrastructure Engineer, OCI Networking](https://jobs.opennash.com/companies/oracle/jobs/c47cb3d0e32b87979fa1/) Oracle · Nashville, TN, United States ### [Optical Network Development Engineer, Core Networking](https://jobs.opennash.com/companies/amazon/jobs/240ff7d225224a58c728/) Amazon · US, WA, Seattle ### [Software Development Engineer, EC2 Networking (VPC Core)](https://jobs.opennash.com/companies/amazon/jobs/3cb40825c99d44797ef7/) Amazon · US, WA, Seattle ### [Software Engineer, Core Networking](https://jobs.opennash.com/companies/apple/jobs/c8b7282e9621bf894b3c/) Apple · San Francisco Bay Area, United States of America OpenNash lists jobs from employers’ own careers sites and does not handle applications.
