• Experience with FIX protocol, Aeron messaging, or low-latency colocation connectivity
• Familiarity with high-frequency trading (HFT) workflows or crypto exchange API integrations
• Strong proficiency in Terraform for cloud infrastructure and Ansible for OS configuration and patching
• Deep understanding of physical network topologies, TCP/IP, UDP, and low-latency network routing
• Hands-on experience with Docker, Docker Compose, Jenkins, and modern deployment pipelines
• Experience setting up production monitoring using Grafana Cloud, Alloy, or Prometheus

Nice to have

• Hands-on scripting capability in Python or Bash, with development experience in Rust or Java
• Experience with hardware acceleration technologies such as FPGAs or SmartNICs, or custom network card driver tuning
• Knowledge of PTP (Precision Time Protocol) or IEEE 1588, or clock synchronization setup for high-precision trade timestamping
