Trade Network Architect

What you'll do

• Establish a network testing lab and build automated benchmarks to evaluate network hardware and protocols.
• Develop Python pipelines and tools to analyze packet captures and telemetry, identify anomalies, and report latency distributions.
• Architect and maintain low-latency trading networks, including routing, multicast, and time-synchronization systems.

What they ask for

• 10+ years designing and operating ultra-low-latency networks in HFT, market making, or quantitative fund environments.
• Advanced Python skills for processing large PCAP datasets, time-series telemetry, and microsecond/nanosecond statistics.
• Hands-on experience building network testing labs and using hardware traffic generators and packet capture tools.
• Deep knowledge of BGP/OSPF, Linux network stack tuning, PTP (IEEE 1588), White Rabbit, PIM-SSM multicast, and large-scale L2/L3 topologies.

Nice to have

• Experience with FPGA-driven low-latency applications or custom accelerator cards in high-performance trading environments.
• Awareness and experience with AI inference networks is a plus but not required.
