Lead Network Automation Architect

We are seeking a highly experienced Lead Network Automation Architect to drive the modernization, automation, and reliability of large-scale global network infrastructure. The ideal candidate will combine deep expertise in enterprise networking, Kubernetes networking, Infrastructure-as-Code, GitOps, CI/CD automation, and advanced troubleshooting of complex hybrid environments. This individual will serve as the highest-level technical authority for network automation, design standards, deployment pipelines, and critical escalations. Experience within telecommunications, VoIP, SaaS platforms, and cloud-native
environments is strongly preferred.

Core Responsibilities:

• Design and implement enterprise-scale Network-as-Code (NaC), Infrastructure-as-Code (IaC), and GitOps solutions using Terraform, Ansible, Python, and Git as the single source of truth, eliminating manual deployment processes.
• Build, optimize, and maintain CI/CD pipelines for network infrastructure, including automated testing, dry-run validation, deployment approval gates, and security/compliance checks to enable zero-downtime deployments.
• Design, deploy, and support Kubernetes networking architectures, including Project Calico, OVN, VXLAN overlays, network policies, container networking, and integration with physical underlay networks.
• Lead the design, modernization, and review of enterprise network architectures, providing expertise in BGP, OSPF, data center networking, multi-site routing, and high-availability solutions.
• Serve as the Tier-4 escalation engineer for complex network incidents, troubleshooting overlay/underlay failures, asymmetric routing, microbursts, path selection issues, and network performance bottlenecks.
• Lead root cause analysis (RCA) and drive long-term remediation and continuous improvement initiatives to enhance network reliability, scalability, and operational efficiency.
• Implement Security-as-Code practices by automating validation and enforcement of ACLs, firewall policies, security groups, and configuration standards before production deployments.

Qualifications

Must-have

• 8+ years of experience in Network Automation, Infrastructure-as-Code (IaC), or Platform Engineering.
• Hands-on expertise in: Network security (Palo Alto firewalls), Load balancing (F5 or equivalent), Routing (MPLS, OSPF, BGP), Switching (Cisco Nexus 9k/7k/5k/2k).
• Working knowledge of Cisco IOS (Nexus OS preferred)
• Strong hands-on experience with Terraform, Ansible, and Python (Netmiko, Nornir, NAPALM).
• Expert knowledge of BGP, OSPF, data center networking, and overlay/underlay network architectures.
• Experience designing and operating Kubernetes networking, including Project Calico, OVN, VXLAN, and Kubernetes CNI.
• Hands-on experience with GitOps and CI/CD tools such as GitLab CI, GitHub Actions, and Jenkins.
• Strong troubleshooting, analytical, and problem-solving skills with experience supporting production enterprise environments.

Nice to have

• Experience with telecommunications technologies, including SIP, RTP, Session Border Controllers (SBC), SIP trunking, and VoIP architectures.
• Knowledge of Linux networking, including network namespaces, virtual interfaces, eBPF, and iptables.
• Experience implementing Telemetry-as-Code, network observability, automated validation frameworks, and proactive monitoring solutions.
• Experience with cloud networking, infrastructure modernization, or large-scale network transformation initiatives.
• Excellent communication skills with the ability to collaborate across engineering, platform, and infrastructure teams.
