Practical experience with Arista and/or Cisco NX-OS in production trading or financial-services environments.
Strong Linux networking fundamentals; comfortable working in a terminal and with performance tooling.
Proven troubleshooting skills for low-latency issues (packet captures, NIC/driver tuning, switch buffers, PTP/NTP).

Responsibilities

Configure and tune Layer 2/3 protocols: BGP, OSPF, VRF, PIM/IGMP, multicast, QoS, STP, NAT.
