Five9 is a leading provider of cloud contact center software, bringing the power of cloud innovation to customers worldwide. \nLiving our values everyday results in our team-first culture and enables us to innovate, grow, and thrive while enjoying the journey together. We celebrate diversity and foster an inclusive environment, empowering our employees to be their authentic selves. \nRole Overview\nTo complement our rapid growth, we are actively sourcing for a Network Engineer to operate in a 24/7 Software-as-a-Service (SaaS) environment maintaining IP Networking components in a production setting.\nIn this role you will:\nDesign, engineer, and oversee highly scalable CI/CD pipelines for automated testing, digital-twin dry-running, and zero-downtime deployment of configurations across massive physical and virtual network fabrics.\nChampion the \"Network-as-Code\" paradigm, establishing enterprise-wide GitOps workflows and enforcing source control (Git) as the absolute single source of truth for all network state, policy, and infrastructure design.\nDrive the strategic vision for network automation, designing complex, reusable code frameworks and Playbooks to permanently eliminate manual configuration and operational \"toil\" at a global scale.\nDesign and optimize massive-scale software-defined networks (SDN) and container networking interfaces (CNIs) supporting ultra-high-throughput, multi-region cloud and bare-metal environments.\nServe as the ultimate technical authority (SME / Tier 4) for complex network, routing, and overlay issues, rapidly deciphering and resolving the most difficult challenges across physical underlays and software-defined layers.\nDesign and implement next-generation telemetry, monitoring, and alerting-as-code platforms, leveraging advanced heuristics for proactive auto-remediation of performance, security, and capacity issues.\nKey Responsibilities\nPartner at a strategic level with Enterprise Designers, SRE leaders, and Platform teams to build and implement highly resilient, secure, and multi-tenant-isolated network infrastructure.\nEstablish coding standards and write/review sophisticated Infrastructure-as-Code (IaC) using Ansible, Terraform, Helm, Python, and Bash.\nLead the engineering, deployment, and optimization of modern overlay and container networking solutions, particularly VXLAN, OVN (Open Virtual Network), and Project Calico.\nDesign the automation of complex security and traffic management policies across enterprise-grade firewalls (Palo Alto/Fortinet) and load balancers (F5 BIG-IP/Cloudflare/Octavia).\nEmbed \"Security-as-Code\" directly into CI/CD pipelines, engineering automated validation gates for security groups, ACLs, and firewall rules prior to production pushes.\nEngineer robust, automated network validation suites to continuously verify network health, state, and complex routing tables (BGP, OSPF) pre- and post-deployment.\nDrive the adoption of code-based infrastructure definitions and dynamic, living technical documentation (e.g., NetBox, Git Markdown), setting the standard for documentation across the engineering organization.\nQualifications & Skills\n8+ years of progressive experience in Network Engineering, DevOps, or SRE roles, with a deeply established focus on large-scale network design, automation, and Infrastructure-as-Code (IaC).\nExpert-level proficiency in engineering complex network automation tooling utilizing Ansible, Terraform, and Python (including deep experience with network-specific libraries like Netmiko, Nornir, or NAPALM).\nDeep design and operational expertise with massive-scale software-defined networks (SDN) and overlays, specifically VXLAN, OVN, and Project Calico.\nAdvanced mastery of Kubernetes networking designs (CNIs, Ingress controllers, Service Mesh, Kube-Proxy behaviors) at an enterprise scale.\nExtensive, expert-level experience engineering and automating enterprise edge, routing, and security fabrics, including Cisco Nexus (9k/7k/5k/2k), Arista, Versa SD-WAN, and firewalls (Palo Alto and Fortinet).\nAuthoritative knowledge of API-driven application delivery and load balancing across monolithic and cloud-native stacks (e.g., F5 BIG-IP AS3, Cloudflare APIs, Octavia LBaaS).\nDeep Linux internals and networking expertise, including advanced knowledge of Linux network namespaces, virtual interfaces, eBPF/iptables, and kernel-level routing.\nCCIE-level (or equivalent) mastery of core routing protocols (BGP, OSPF, MPLS, EVPN) and a comprehensive understanding of how virtual/container overlay networks map to physical underlays.\nExtensive experience designing and scaling CI/CD platforms (e.g., GitLab CI, Jenkins, GitHub Actions) and implementing test-driven development (TDD) for infrastructure changes.\nUnparalleled troubleshooting capabilities utilizing advanced packet analysis (tcpdump/Wireshark), NetFlow, and log aggregation platforms to trace asymmetric routing and microburst traffic across hybrid fabrics.\nProven track record of technical leadership, including mentoring mid-level engineers, leading design review boards, and driving cross-functional engineering initiatives.\nDeep telecommunications background, specifically VoIP, RTP, SIP peering/trunking, and Session Border Controllers (SBC), is highly advantageous.\nExceptional verbal and written communication skills, with the ability to translate complex technical concepts to executive stakeholders while fostering a collaborative, DevOps-oriented engineering culture.\nDiversity & Inclusion\nFive9 embraces diversity and
