What you will do

• Own the operational health, configuration consistency, and performance tuning of large-scale Ethernet front-end fabrics (leaf-spine / Clos).
• Lead the diagnosis and resolution of complex network incidents (P0/P1) spanning optics, routing, switching hardware, and storage connectivity.
• Drive blameless postmortems and implement preventative fixes to improve long-term fabric stability and availability.
• Partner with SREs to define requirements for automation and contribute to network provisioning, validation, and monitoring systems.
• Collaborate with Network Architecture teams to validate designs and enforce standards for routing, congestion management, and firmware baselines.
• Monitor fabric utilization and performance to identify bottlenecks and ensure predictable latency and throughput.

Requirements

• 5+ years of experience in network engineering, with at least 3 years operating large-scale Ethernet data centre or cloud networks.
• Deep, hands-on operational experience with Arista (EOS) and/or Nokia platforms.
• Strong expertise in BGP, OSPF, ECMP, EVPN-VXLAN, and leaf-spine architectures.
• Proven experience with long-haul circuits and DCI (dark fiber, carrier Ethernet, coherent optics).
• Proficiency in Python, Go, or shell scripting for automation and data analysis.
• Experience working in a 24/7 operational environment with a strong focus on reliability.

Nice to have

• Extensive experience with Arista or Nokia platforms at scale.
• Familiarity with front-end network patterns specifically for large AI clusters.
• Experience operating large-scale DCI / long-haul optical or carrier networks.
