Company

hirify.global applies scientific research, mathematics, computer science, physics, and engineering to algorithmic trading and operates sophisticated computing infrastructure.

What you will do

• Build, test, and optimize global ultra-low-latency networks for high-frequency trading and exchange colocation sites.
• Establish and operate a network testing lab with automated benchmark frameworks using Spirent and Ixia traffic generators.
• Develop Python pipelines and tools to analyze PCAP captures, telemetry, queue depth metrics, binary network logs, and latency distributions.
• Evaluate and benchmark SmartNICs, switches, FPGAs, transceivers, network adapters, and network co-processors with hardware engineering teams.
• Design and maintain L2/L3 architectures, including BGP, OSPF, PIM-SSM/IGMP multicast trees, and resilient market data delivery systems.
• Oversee PTP IEEE 1588v2 and White Rabbit synchronization, while evaluating emerging low-latency networking hardware and software.

Requirements

• 10+ years of experience designing and operating ultra-low-latency networks in HFT, market making, or quantitative fund environments. Exchange colocation, market data feeds, and FIX, OUCH, and ITCH order routing protocols are required.
• Advanced Python skills, including pandas, NumPy, or PyArrow, for large PCAP datasets, time-series telemetry, and microsecond/nanosecond statistics.
• Hands-on experience building network testing labs with Spirent/Ixia hardware traffic generators and packet capture tools.
• Expertise with Arista 7130, Cisco Nexus 3550/3548, LDA L1 switches, AMD Solarflare, and NVIDIA Mellanox hardware.
• Experience with FPGA-driven low-latency applications or custom accelerator cards in high-performance trading environments.
• Deep knowledge of BGP, OSPF, Linux network stack tuning, PTP IEEE 1588, White Rabbit, PIM-SSM multicast, and large-scale L2/L3 topologies.
• Proficiency with Ansible, SQL, and Python network automation tools such as Scapy, Netmiko, or AsyncIO.
• Experience with Victoriametrics, Prometheus, Grafana, and Docker observability stacks.

Nice to have

• Awareness and experience with AI inference networks.
