Principal Network Architect

We are seeking a visionary and technically elite Principal Network Architect to lead the design, architecture, and operations of our global network infrastructure. This role encompasses on-premises data centers, multi-cloud environments (including AWS, Azure, and/or GCP), and Kubernetes-based networking. You will drive our strategic direction, influence global network policies, and act as a critical escalation point for complex networking issues.

Key Responsibilities

• Design & Architecture
• Architect and evolve a hybrid global network across on-prem and public cloud environments.
• Define and enforce network segmentation, routing, firewall, VPN, and DNS strategies across platforms.
• Integrate container-based networking with Kubernetes (e.g., CNI plugins, service meshes, ingress controllers).
• Cloud Networking
• Build and manage scalable, secure network infrastructure in AWS, Azure, and/or GCP.
• Implement hybrid connectivity models such as Direct Connect, ExpressRoute, and VPN gateways.
• Optimize cloud network costs and performance with advanced routing and traffic policies.
• Kubernetes & Microservices Networking
• Implement service meshes (e.g., Istio, Linkerd) and ingress/egress policies for microservices communication.
• Drive adoption of zero-trust networking within Kubernetes clusters.
• Collaborate with platform teams to ensure seamless integration between networking and container orchestration.
• Operations & Troubleshooting
• Serve as highest-level escalation for network performance, latency, and connectivity issues.
• Own monitoring, logging, and alerting for global network health and security.
• Mentor global engineering teams and lead incident response for critical network-related outages.
• Strategy & Leadership
• Define global network strategy aligned with organizational security and compliance objectives.
• Evaluate and implement next-gen technologies (e.g., SD-WAN, NAC, cloud firewalls, NDR).
• Lead vendor evaluations, RFPs, and lifecycle management for network infrastructure and tooling.

Required Qualifications

• 10+ years of experience in network engineering, with at least 3 years in a principal or lead role.
• Deep expertise in enterprise networking: routing, switching, firewalls (e.g., Palo Alto, Fortinet), BGP, OSPF.
• Proven experience with cloud-native networking across AWS, Azure, or GCP.
• Advanced knowledge of Kubernetes networking: CNI plugins, DNS, ingress/egress traffic flow, network policies.
• Strong knowledge of automation (e.g., Terraform, Ansible) for network provisioning and management.
• Experience with monitoring tools (e.g., Prometheus, Grafana, ThousandEyes, Wireshark).
• Strong scripting or programming skills (Python, Go, or Bash).
• Excellent communication and collaboration skills across global, cross-functional teams.
