Node.js Jobs in Web3

Location: RemoteType: Full-TimeOn-Call Requirement: Yes (Rotational Operational Support) 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.

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.

Nice to Have

Experience in crypto trading environments (CeFi, DeFi, or both). Familiarity with performance testing tools and practices. Experience with supply chain security, secrets management, and secure build pipelines.
