Senior Infrastructure Engineer - Trading Systems

Responsibilities

Low-Latency Architecture: Design, provision, and maintain ultra-low latency AWS and hybrid network topologies, including VPCs, exchange gateways, and regional deployment expansions.

Performance Tuning: Optimize Linux OS kernels and compute performance using CPU isolation (isolcpus), AWS Cluster Placement Groups, and enhanced networking (ENA/ENI).

Infrastructure as Code: Drive infrastructure automation, provisioning, and configuration management using Terraform and Ansible.

Platform Scaling: Architect infrastructure to support expanding Exchange Market Making (EMM), Project Market Making (PMM), and TradFi exchange convergences.

Observability & Reliability: Build telemetry and monitoring pipelines using Grafana Cloud and Alloy to ensure continuous visibility into platform performance.

Technical Leadership: Guide the technical roadmap, mentor junior engineers, and act as an escalation lead for critical system incidents.

Key Qualifications

5+ years of experience in Infrastructure Engineering, Systems Engineering, or SRE, with a focus on low-latency electronic trading environments.

Deep Linux Internals Expertise: Advanced experience with kernel-level performance tuning, memory management, and network I/O optimization (isolcpus, network profiling, ring buffers).

AWS Low-Latency Design: Demonstrated experience leveraging AWS low-latency constructs (Placement Groups, ENA/ENI, high-performance EC2 instance optimization).

Trading Protocols & Infrastructure: Experience with FIX protocol, Aeron messaging, or low-latency colocation connectivity.

HFT & Market Workflows: Familiarity with high-frequency trading (HFT) workflows or crypto exchange API integrations.
