Descrição

• Design, 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. • Champion 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. • Drive 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. • Design and optimize massive-scale software-defined networks (SDN) and container networking interfaces (CNIs) supporting ultra-high-throughput, multi-region cloud and bare-metal environments. • Serve 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. • Design and implement next-generation telemetry, monitoring, and alerting-as-code platforms, leveraging advanced heuristics for proactive auto-remediation of performance, security, and capacity issues. • Partner 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. • Establish coding standards and write/review sophisticated Infrastructure-as-Code (IaC) using Ansible, Terraform, Helm, Python, and Bash. • Lead the engineering, deployment, and optimization of modern overlay and container networking solutions, particularly VXLAN, OVN (Open Virtual Network), and Project Calico. • Design the automation of complex security and traffic management policies across enterprise-grade firewalls (Palo Alto/Fortinet) and load balancers (F5 BIG-IP/Cloudflare/Octavia). • Embed "Security-as-Code" directly into CI/CD pipelines, engineering automated validation gates for security groups, ACLs, and firewall rules prior to production pushes. • Engineer robust, automated network validation suites to continuously verify network health, state, and complex routing tables (BGP, OSPF) pre- and post-deployment. • Drive 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.

🎯 Requisitos

• 8+ 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). • Expert-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). • Deep design and operational expertise with massive-scale software-defined networks (SDN) and overlays, specifically VXLAN, OVN, and Project Calico. • Advanced mastery of Kubernetes networking designs (CNIs, Ingress controllers, Service Mesh, Kube-Proxy behaviors) at an enterprise scale. • Extensive, 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). • Authoritative 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). • Deep Linux internals and networking expertise, including advanced knowledge of Linux network namespaces, virtual interfaces, eBPF/iptables, and kernel-level routing. • CCIE-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. • Extensive experience designing and scaling CI/CD platforms (e.g., GitLab CI, Jenkins, GitHub Actions) and implementing test-driven development (TDD) for infrastructure changes. • Unparalleled troubleshooting capabilities utilizing advanced packet analysis (tcpdump/Wireshark), NetFlow, and log aggregation platforms to trace asymmetric routing and microburst traffic across hybrid fabrics. • Proven track record of technical leadership, including mentoring mid-level engineers, leading design review boards, and driving cross-functional engineering initiatives. • Deep telecommunications background—specifically VoIP, RTP, SIP peering/trunking, and Session Border Controllers (SBC)—is highly advantageous. • Exceptional verbal and written communication skills, with the ability to translate complex technical concepts to executive stakeholders while fostering a collaborative, DevOps-oriented engineering culture.
