• Solid understanding of modern data center networking, including BGP, OSPF, ECMP, EVPN-VXLAN, and leaf-spine architectures.
• Proven experience with long-haul circuits and DCI (dark fiber, carrier Ethernet, coherent optics)
• Experience with storage networking over Ethernet and shared storage connectivity
• Proven ability to troubleshoot complex network issues using Linux-based tooling and fabric diagnostics
• Proficiency in Python, Go, or shell scripting for automation, data analysis, or configuration management
• Experience working in a 24/7 operational environment with a strong focus on reliability and toil reduction

Preferred Qualifications (Nice to have):

• Extensive hands-on experience with Arista or Nokia platforms at scale
• Deep familiarity with front-end network patterns for large AI clusters (inference traffic, management networks, and storage integration)
• Experience operating large-scale DCI / long-haul optical or carrier networks
• Strong background in network observability and telemetry systems (streaming telemetry, sFlow, Prometheus, Grafana, etc.)
• Prior experience in automation-first network operations or building internal tooling
