What You'll Do

• Configure and maintain high-throughput (100Gbps+) Arista and Cisco switches, optimizing performance in demanding environments
• Architect, deploy, and troubleshoot complex Layer 2 and Layer 3 Ethernet networks including VLANs, LACP, load balancing, and QoS configurations
• Implement, tune, and debug advanced IP networking protocols (IPv4, IPv6) to ensure reliable connectivity and minimized latency
• Integrate and operate whitebox network hardware utilizing ONIE, SONiC, and Switch Abstraction Interface (SAI) for software-driven networking solutions
• Automate infrastructure tasks and perform scripting using Bash and Python; administer Linux networking services including PXE boot provisioning, DNS, and DHCP

What You Need

• In-depth hands-on experience with Arista and/or Cisco switches managing high-speed 100Gbps+ Ethernet environments
• Comprehensive understanding of Ethernet networks, VLANs, LACP, load balancing, and advanced QoS mechanisms
• Strong knowledge and operational experience with IPv4 and IPv6 addressing, routing, and protocol configuration
• Proficiency in troubleshooting and supporting RDMA technologies, including RoCE and RoCEv2
• Hands-on whitebox network equipment experience with ONIE, SONiC, and SAI-based platforms; solid Linux networking skills and practical scripting/automation experience in Bash and Python

Nice to Have

• Familiarity with large-scale data center architectures or high-performance computing network topologies
• Experience integrating network hardware into software-defined or disaggregated network environments
• Expert-level knowledge in network automation frameworks or infrastructure as code such as Ansible or NetBox
• Exposure to telemetry, monitoring, or performance tuning for low-latency/high-throughput network operations; prior work with open networking standards or programmable data plane technologies
