The Role
We are looking for an experienced DevOps Engineer to design, operate, and optimize ultra-low-latency infrastructure supporting high-frequency trading, market-making, and real-time risk systems across TradFi and Web3 venues.
This role sits directly between trading, quant, and systems engineering, with ownership over reliability, performance, and observability of latency-sensitive trading systems. You will work on bare-metal, cloud, and hybrid environments where milliseconds and microseconds matter.
Responsibilities
Build and maintain reliable, low-latency infrastructure for trading and market-making systems
Support production systems for order execution, market data, hedging, and risk management
Help ensure systems remain stable and available during trading hours through sensible redundancy and failover
Work on system and network performance tuning (e.g. kernel settings, NUMA, IRQ affinity, TCP/UDP tuning) as needed
Participate in performance and latency investigations across the trading stack
Help profile and understand system behaviour, including:
Order and market data latency
Risk and inventory updates
CPU, memory, disk, and network usage
Occasionally visit data centers to support low-latency setups, hardware checks, and basic latency measurements
Manage containerized and non-containerized workloads (Docker, Kubernetes, bare-metal)
Automate infrastructure and operations using Infrastructure as Code tools
Requirements
5+ years of experience in DevOps, SRE, or Platform Engineering roles
Comfort working with Linux systems, networking, and performance troubleshooting
Experience diagnosing CPU, memory, storage, and I/O issues in production systems
Hands-on experience with Docker and Kubernetes (or similar tools)
Familiarity with CI/CD pipelines (e.g. GitHub Actions, GitLab CI, Jenkins)
Experience with Infrastructure as Code (e.g. Terraform, Pulumi, Ansible, or similar)
Experience working with a mix of bare-metal, on-premise, and cloud environments (AWS, GCP, etc.)
Familiarity with observability tools such as Prometheus, Grafana, and Loki
Interest in crypto, trading systems, or decentralized finance (deep expertise not required)
A thoughtful problem-solver who enjoys learning and improving systems over time
A collaborative mindset and comfort working in a fast-moving, small team
