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 up to 25% of travel., * 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. ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [IP Authentication: A Tale of Performance Pitfalls and Challenges in Prod](https://www.wearedevelopers.com/videos/1413-ip-authentication-a-tale-of-performance-pitfalls-and-challenges-in-prod) - [IoT: The road to sustainability](https://www.wearedevelopers.com/videos/557-iot-the-road-to-sustainability) - [Your Infrastructure Is Not a Playground: AI Agents for Infra Done Right](https://www.wearedevelopers.com/videos/2084-your-infrastructure-is-not-a-playground-ai-agents-for-infra-done-right) - [Computer Vision from the Edge to the Cloud done easy](https://www.wearedevelopers.com/videos/263-computer-vision-from-the-edge-to-the-cloud-done-easy) - [Small, Secure, Interconnected: The next Internet Protocol](https://www.wearedevelopers.com/videos/100062-small-secure-interconnected-the-next-internet-protocol) ## Related Articles - [Best Paying Jobs in Technology](https://www.wearedevelopers.com/magazine/256-best-paying-jobs-in-technology) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [Basic And Advanced Networking in Dart and Flutter](https://www.wearedevelopers.com/magazine/112-basic-and-advanced-networking-in-dart-and-flutter)
