• Collaborate across teams to enhance platform reliability, performance, scalability, and security.
• Provision high‑throughput messaging paths (Aeron, FIX gateways) to support venue expansions for market making and regional growth.
• Drive infrastructure automation, network topology design, and OS configurations using Terraform and Ansible.
• Build real‑time telemetry pipelines using Grafana Cloud, Alloy, and Prometheus to detect latency spikes and system issues.
• Drive continuous platform efficiency, reduce tick‑to‑trade latency, and accelerate deployment cycles.
• Practice sustainable incident response, reduce MTTR, establish error budgets, and conduct blameless postmortems.
• Share on‑call rotation duties and serve as a primary escalation point for production incidents.
• Enforce security best practices across all trading infrastructure to minimize attack surfaces and guarantee data integrity.

Minimum Qualifications
