REQUIREMENTS

• 5+ years in DevOps/SRE roles focused on high-performance, production-grade systems.
• Strong Linux systems background and infrastructure automation skills using Ansible.
• Proficient with Terraform and experienced in managing cloud infrastructure (AWS required, Azure a plus).
• Deep understanding of performance engineering at both the system and network levels, including tuning, profiling, and capacity planning.
• Experience working in latency-sensitive environments, ideally in trading, fintech, or other real-time domains.
• Excellent scripting and automation capabilities using Python and Bash; knowledge of Go, JavaScript, or TypeScript is a plus.
• Familiarity with containerized workloads (Docker essential, Kubernetes nice to have).
• Hands-on experience with observability stacks (Prometheus, Grafana) and production incident response.
• Understanding of blockchain APIs, DeFi protocols, and RPC node management is highly desirable.Knowledge of cloud networking, security best practices, IAM, SIEM tools, and endpoint security on Mac/Linux systems.

ABOUT THE ROLE

We’re looking for a mid-level DevOps Engineer to join our globally distributed team and help scale and operate the infrastructure that powers millions of trades daily across CeFi and DeFi venues. You’ll play a mission-critical role in ensuring the performance, reliability, and security of our systems in one of the most demanding environments in tech: digital asset trading.
This isn’t just an infrastructure role. You’ll be a key player in building and operating systems where milliseconds matter and downtime is never an option. We need someone who can go beyond automation — someone who understands how low-level performance issues, network latency, and cloud inefficiencies can affect real-world trading outcomes.
The position involves participating in a rotational on-call schedule, collaborating with team members across Australia, Hong Kong, and Europe, and working proactively to ensure 24/7 uptime and operational excellence.

KEY RESPONSIBILITIES

• Ensure the performance and reliability of mission-critical trading infrastructure by proactively identifying and resolving bottlenecks at all layers: compute, network, storage, and application.
• Support, operate, and continuously improve highly available, low-latency systems under global trading load, with a strong focus on automation and enabling self-service for internal teams.
• Participate in a rotational on-call schedule, handling real-time operational incidents, root cause analysis, and long-term preventive improvements.
• Use metrics and observability tools (Prometheus, Grafana, etc.) to detect anomalies, monitor performance trends, and support incident response.
• Build, manage, and scale infrastructure-as-code using Terraform and configuration management tools like Ansible.
• Maintain and optimize containerized services using Docker, with opportunities to expand into Kubernetes.
• Collaborate closely with trading, engineering, and security teams to align infrastructure improvements with application demands.
• Implement robust security practices, including IAM, threat detection, and secure CI/CD pipelines, to support high-trust production environments.Apply low-level optimization strategies to improve throughput, reduce latency, and increase system efficiency across diverse environments.
