Low Latency Network Engineer (Trading Infrastructure)

Experience: 10 plus years in network/infrastructure engineering (trading/HFT experience strongly preferred), * Bachelor’s degree in Computer Science, IT, Electronics/Telecommunications or related field. \n

• 10 plus years of hands-on networking experience, ideally in HFT, prop trading, exchanges or other latency-sensitive environments. \n

• Deep knowledge of TCP/IP, UDP, multicast, routing (BGP/OSPF), switching, VLANs and data-centre networking. \n

• Practical experience with Arista and/or Cisco NX-OS in production trading or financial-services environments. \n

• Strong Linux networking fundamentals; comfortable working in a terminal and with performance tooling. \n

• Proven troubleshooting skills for low-latency issues (packet captures, NIC/driver tuning, switch buffers, PTP/NTP).

Design, build and support the high-performance network that powers a proprietary trading firm’s global strategy. You’ll work on ultra-low-latency LAN/WAN, multicast market-data distribution and exchange connectivity across colocation data centres, with a heavy focus on performance, resilience and automation. This role sits at the core of the trading platform-close to traders, developers and infrastructure teams-where microsecond-level improvements matter.

\n \n

• Design, implement and maintain low-latency network infrastructure for trading applications (Arista/Cisco, leaf-spine, bare-metal servers). \n

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

• Support exchange connectivity, cross-connects and colocation deployments; work with carriers and data-centre teams. \n

• Troubleshoot latency, jitter, packet loss and microbursts using tcpdump, Wireshark, NIC stats and switch telemetry. \n

• Automate network changes and validations using Python, Bash and/or Ansible; contribute to IaC and CI/CD pipelines. \n

• Monitor network health and performance; create dashboards and alerts for proactive incident management. \n
