Senior Trading Systems DevOps Engineer

Responsibilities

• Build, scale, and optimize core low-latency trading platforms.
• Architect AWS and hybrid cloud infrastructure for microsecond execution using kernel tuning (isolcpus), AWS Placement Groups, and enhanced networking (ENA/ENI).
• Design and maintain release pipelines for core trading engines (OMS, EMS, Gateways), ensuring zero-downtime deployments and deterministic rollbacks.
• 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

• Bachelor’s degree with 5+ years of experience as an Infrastructure or Systems Engineer in low-latency electronic trading environments.
• Deep Linux kernel knowledge: performance tuning, memory management, and network I/O optimization (isolcpus, CPU pinning, ring buffers).
• Hands-on expertise optimizing AWS low-latency constructs (Placement Groups, ENA/ENI, high-performance EC2 selection).
• Proven track record productionizing low-latency trading systems across cloud, on-prem, and colocation environments.
• Experience building CI/CD pipelines for stateful trading systems using Jenkins, ArgoCD, or GitHub Actions.
• Direct experience with FIX protocol execution flows and low-latency Aeron messaging (IPC/UDP).
• Strong knowledge of physical network design, TCP/IP, UDP, WebSockets, and low-latency routing.
• Advanced proficiency with Terraform for infrastructure provisioning and Ansible for configuration management.
• Solid experience managing containerized workloads via Docker, Docker Compose, and Kubernetes.
• Experience securing container base images using minimal distributions like Chainguard.
• Expertise in observability, debugging, and system tuning using Grafana Cloud, Alloy, or Prometheus.
• Fluent in Python and Bash scripting.

Preferred Qualifications

• Hands-on development exposure to Rust or Java for cross-functional debugging of execution engines.
• Experience implementing operational frameworks (SLOs, SLAs, Error Budgets) for trading desks.
• Deployment expertise with canary and blue/green release strategies for stateful systems.
• Strong analytical, communication, and problem-solving skills under time-sensitive conditions.
• Working knowledge of databases (MySQL, PostgreSQL) and key-value stores (Redis).
• Exposure to algorithmic trading strategies, market-making mechanics, or crypto exchange APIs.
