Data Center Network Engineer

Job Summary: The Supermicro Data Center team is seeking a Data Center Network Engineer to Support daily operations of high-performance networking infrastructure within our AI lab(s) and data center environments. This role focuses on rack-level deployment, cabling, switch configuration support, and troubleshooting connectivity for GPU clusters and storage systems.

Essential Duties and Responsibilities: Data Center Network Deployment: Rack, stack, cable, label, and commission high-speed Ethernet switches supporting 10/25/100/200/400GbE network infrastructure in AI labs and high-density data center environments. Fiber & High-Speed Connectivity: Install, inspect, label, and validate fiber-optic infrastructure and high-speed interconnects, including QSFP/OSFP transceivers, DACs, AOCs, and associated cabling. Switch Configuration: Configure and validate switch ports, including access and trunk interfaces, VLAN assignments, link aggregation, and other Layer 2 configurations under established network standards and engineering guidance. Spine-Leaf Network Deployment: Support deployment, expansion, and troubleshooting of spine-leaf network fabrics used for high-performance AI/ML and GPU compute environments. GPU & Server Connectivity: Install and validate network connectivity for GPU servers, compute nodes, and high-performance NICs. Perform link validation and confirm expected connectivity, link speeds, and interface status. Network Troubleshooting: Diagnose Layer 1–Layer 3 connectivity issues involving switches, optics, transceivers, fiber, DAC/AOC cables, NICs, and network interfaces. Isolate faults and escalate complex issues to senior network engineers as required. Performance & Link Validation: Perform connectivity and basic performance testing using tools such as ping, iperf, interface diagnostics, and switch telemetry to validate network links and identify performance anomalies. Network Configuration Support: Assist with MLAG, LACP, port-channel, VLAN, and other network configurations under the direction of senior network engineers while following established configuration standards and change-control procedures. Hardware Replacement & Break/Fix: Troubleshoot and replace failed optics, transceivers, cables, network interface components, and switch line cards. Verify system functionality following component replacement. Network Monitoring: Monitor network health dashboards and telemetry for link failures, packet errors, interface flaps, abnormal utilization, and other connectivity or performance issues. Topology & Documentation: Maintain accurate documentation of rack layouts, switch configurations, fiber paths, port mappings, device inventory, and physical/logical network topology. Commissioning & Deployment Support: Support network commissioning, rack burn-in, and deployment activities in coordination with server, electrical, liquid cooling, facilities, and data center operations teams. Incident Response & Root Cause Analysis: Respond to network connectivity incidents, assist with fault isolation and root-cause analysis (RCA), and document corrective actions and recurring failure modes. Lead 24/7 NOC operations, direct technician triage, drive major incident escalations to hit MTTA/MTTR SLAs, and optimize monitoring tools and runbooks for maximum infrastructure uptime.

Qualifications: BS degree in Computer Networking, Information Technology, or a related technical field preferred.,5+ years of hands-on experience supporting network infrastructure in data centers, AI labs, high-density compute environments, or other mission-critical facilities. Strong working knowledge of TCP/IP, IPv4 addressing, subnetting, VLANs, trunking, Layer 2/Layer 3 concepts, and basic routing principles Hands-on experience with enterprise/data center switches such as Cisco, Arista, or equivalent platforms. Experience with switch port configuration, interface diagnostics, VLANs, LACP/port channels, and basic MLAG concepts is preferred. Experience working with 100GbE and higher-speed network infrastructure, including QSFP/OSFP optics, DAC/AOC cables, fiber connectivity, and high-speed server NICs. Familiarity with GPU servers, AI/ML clusters, high-density compute racks, and the networking requirements associated with distributed GPU workloads. Working knowledge of data center network architectures, including spine-leaf topologies and east-west traffic patterns. Basic proficiency with Linux command-line tools and network troubleshooting utilities such as ping, traceroute, iperf, and interface diagnostics. Basic understanding of firewalls, access controls, network segmentation, VPN technologies, and common data center security practices. Strong analytical and problem-solving skills with the ability to troubleshoot Layer 1–Layer 3 connectivity issues, isolate hardware or configuration faults, and escalate complex issues appropriately. Salary Range$115,000 - $130,000 The salary offered will depend on several factors, including your location, level, education, training, specific skills, years of experience, and comparison to other employees already in this role. In addition to a comprehensive benefits package, candidates may be eligible for other forms of compensation, such as participation in bonus and equity award programs.
