Low Latency Trading Infrastructure Engineer

What you'll do

• Design low-latency compute topologies including bare-metal servers, NICs, and FPGA-enabled hardware.
• Optimize Linux and Windows operating systems for deterministic performance using kernel bypass, CPU pinning, and NUMA tuning.
• Build repeatable benchmarking harnesses to measure tick-to-trade latency, jitter, and throughput.
• Architect and deliver high-performance colocation environments and Layer 1/Layer 2 network configurations.
• Execute infrastructure provisioning and deployments within air-gapped or network-segmented environments.
• Lead bare-metal automation and infrastructure-as-code practices using tools like Ansible, Terraform, and Puppet.
• Troubleshoot hardware, OS, and network stack issues under time-sensitive, high-impact conditions during market hours.
• Manage hardware lifecycle refresh planning, including aging tracking and vendor support coordination.

What we're looking for

• 6+ years of hands-on experience in low latency infrastructure engineering within electronic trading or high-performance financial technology environments.
• Proven experience building and operating exchange colocation environments for Equities or multi-asset electronic trading platforms.
• Deep expertise in low latency network architecture, including multicast market data distribution and Precision Time Protocol (PTP) synchronization.
• Advanced Linux systems engineering proficiency in RHEL, including kernel tuning, CPU pinning, NUMA optimization, and interrupt affinity.
• Hands-on experience with kernel bypass and packet acceleration technologies such as DPDK, XDP, Solarflare OpenOnload, and FPGA-based NICs.
• Proficiency in scripting and automation using Python or Bash to build benchmarking and telemetry tools in air-gapped environments.
• Experience with infrastructure automation tools like Ansible, Terraform, or Puppet and CI/CD pipelines like Jenkins, GitLab CI/CD, or GitHub Actions.
• Bachelor's degree in Computer Science, Electrical Engineering, Information Technology, or a related technical discipline, or equivalent practical experience.
