Senior DevOps Engineer

We are seeking a Senior DevOps Engineer to play a critical role in designing, operating, and scaling high-performance, low-latency trading infrastructure. This role sits at the intersection of engineering, trading, and quantitative research, where infrastructure reliability and speed directly impact live trading performance.

You will own automation, tooling, observability, and operational excellence across on-premises systems, co-located data centers, and containerized environments, while partnering closely with software engineers, traders, and quants in a fast-paced, performance-driven environment.

This is a hands-on senior role with real ownership, minimal bureaucracy, and direct influence over system design decisions.

• Architect, build, and maintain highly reliable, low-latency infrastructure supporting automated trading systems.
• Own end-to-end DevOps practices across on-prem, co-located data centers, and containerized platforms.
• Design and implement automation for deployments, workflows, system operations, and data pipelines.
• Develop internal tooling to improve system reliability, observability, performance, and operational efficiency.
• Lead troubleshooting efforts for complex, production-critical issues spanning applications, networks, operating systems, and hardware.
• Implement and maintain Infrastructure as Code (IaC) and configuration management practices.
• Manage and optimize containerized environments and support application deployments in latency-sensitive systems.
• Partner with engineers and quants to ensure production readiness, scalability, and fault tolerance.
• Support database administration, monitoring, performance tuning, and reliability as part of overall platform health.
• Design and refine logging, metrics, alerting, and monitoring to enable rapid detection and response during trading hours.
• Produce and maintain clear documentation, runbooks, and operational procedures.
• Participate in on-call or rotation-based support during critical trading windows.
