Network Architect

Network Service Architect

This Architect will lead the team of other Network Engineers for our Coupang project. Network Lead needs to know the following:

• Nvidia SuperPod - DGX (HEAVILY preferred and if they don't have this they need to be solid on every other bullet point)
• Infiniband
• CulumlusOS
• BGP
• WAN Link integration
• Mellanox switches
• Fortinet Firewalls
• Nvidia SuperPod experience
• These resources should be subject matter experts on HPC networking

Key Responsibilities:

• Underlay Network Design: Design and implement underlay network topologies for WAN, LAN, and VXLAN environments, ensuring robust, scalable, and fault-tolerant networks.
• Device Configuration: Configure and manage core network devices including switches, routers, and firewalls, with a focus on performance, security, and operational efficiency.
• SDN Integration: Implement and maintain Software-Defined Networking (SDN) solutions, ensuring the network is automated, flexible, and easily adaptable to evolving needs.
• Network Automation: Develop and deploy automation scripts and tools to streamline network provisioning, configuration, and management tasks.
• Performance Optimization: Monitor network performance and troubleshoot network issues across multiple layers to ensure low-latency, high-availability, and optimal traffic routing.
• Security Configuration: Ensure the network infrastructure adheres to best practices for security, including the configuration of firewalls, access control lists (ACLs), and other protective measures.
• Documentation: Maintain comprehensive documentation for network designs, configurations, troubleshooting steps, and automation processes.
• Collaboration: Work closely with other infrastructure teams (e.g., Cloud, DevOps, Systems, Security) to ensure seamless network integration and support for cross-functional projects.
• Incident Response: Participate in incident resolution and troubleshooting of network-related issues, providing root cause analysis and implementing solutions to prevent recurrence.

Qualifications:

• Extensive experience in designing and managing underlay network infrastructure, including WAN, LAN, and VXLAN.
• Proven experience with SDN (Software Defined Networking) technologies and platforms (e.g., Cisco ACI, VMware NSX, etc.).
• Strong knowledge of network hardware, including switches, routers, and firewalls (Cisco, Juniper, Arista, Fortinet, etc.).
• Hands-on experience with network automation tools (e.g., Ansible, Python scripting, Cisco DNA, or other automation platforms).
• Deep understanding of IP networking concepts, routing protocols (OSPF, BGP, etc.), and network security best practices.
• Familiarity with network monitoring and troubleshooting tools (e.g., Wireshark, SolarWinds, Nagios, etc.).
• Strong problem-solving skills, with the ability to resolve complex network issues across different network layers.
• Experience with cloud networking concepts and integration of on-premise networks with cloud environments (AWS, GCP, Azure).
• Solid understanding of network security protocols and firewall management (e.g., ACLs, VPNs, NAT).
• Excellent documentation and communication skills, with the ability to collaborate effectively across teams.

Preferred Skills:

• Certifications such as CCNP, CCIE, JNCIP, or equivalent.
• Experience with large-scale enterprise or data center networks.
• Familiarity with network performance and monitoring tools like NetFlow, SNMP, and sFlow.
• Experience with DevOps and CI/CD methodologies in a network automation context.
• Familiarity with network telemetry and monitoring solutions (e.g., OpenTelemetry, Prometheus, Grafana).
