In today’s fast-evolving digital landscape, cloud infrastructure is the backbone of scalable, secure, and high-performance applications—especially in the world of cryptocurrency and blockchain technology. As OKX continues to expand its global footprint, we are seeking a Senior Staff Engineer to lead the design, optimization, and operation of our enterprise-grade hybrid cloud environment across AWS and Alibaba Cloud.
This role sits at the intersection of architecture, operations, and innovation—driving efficiency, resilience, and compliance while supporting one of the world’s most trusted crypto platforms. If you're passionate about cloud-native technologies, large-scale infrastructure, and shaping the future of decentralized finance, this is your opportunity.
Why This Role Matters
At OKX, infrastructure isn’t just a support function—it’s a strategic enabler. The Senior Staff Engineer will be responsible for managing the full lifecycle of hybrid cloud systems that power millions of transactions daily. From optimizing compute costs to ensuring 99.99% availability, your work will directly impact platform reliability, security, and user experience.
With OKX serving both retail traders and major financial institutions, the scale and complexity of our cloud operations demand deep technical expertise and proactive leadership. You’ll play a pivotal role in maintaining our Proof of Reserves integrity, securing sensitive data, and enabling seamless growth across global markets.
Core Responsibilities
Cloud Platform Architecture & Operations
You will architect, deploy, and maintain robust cloud environments on both Amazon Web Services (AWS) and Alibaba Cloud, ensuring seamless interoperability and performance.
- Manage core services including EC2/ECS, S3/OSS, VPC, Lambda/Function Compute, EKS/ACK, and more.
- Design auto-scaling, fault-tolerant architectures with intelligent load balancing and traffic routing.
- Optimize network performance using AWS Direct Connect and Alibaba Cloud CEN (Cloud Enterprise Network) to reduce latency and improve connectivity between regions.

Monitoring & Incident Management
Proactive visibility is key to preventing outages. You’ll build comprehensive monitoring frameworks that provide real-time insights across all layers.
- Implement full-stack observability using AWS CloudWatch, Alibaba Cloud CloudMonitor, Prometheus + Grafana, and ELK Stack.
- Define alerting thresholds for CPU utilization, memory pressure, disk I/O, and network throughput.
- Lead incident response for critical outages, conduct root cause analysis (RCA), and implement corrective actions to prevent recurrence.
Cost Optimization & Resource Efficiency
Cloud spend can spiral without governance. Your mission includes driving FinOps principles to maximize value and minimize waste.
- Analyze usage patterns and recommend cost-saving measures such as reserved instances, spot instances, and auto-scaling policies.
- Apply intelligent storage tiering—like AWS S3 Intelligent-Tiering and Alibaba Cloud OSS Archive—to reduce long-term storage costs.
- Enforce resource quotas and tagging standards to track spending by team, project, or service.

Security & Compliance
Security is non-negotiable in the crypto space. You’ll ensure our cloud environments meet the highest standards of protection and regulatory alignment.
- Harden cloud configurations using security groups, IAM policies (AWS), and RAM permissions (Alibaba Cloud).
- Conduct regular audits with tools like AWS Security Hub and Alibaba Cloud Security Center.
- Enable detailed logging via AWS CloudTrail and Alibaba Cloud DAS for database activity monitoring and compliance reporting.
- Implement advanced protections including WAF and DDoS mitigation (AWS Shield, Alibaba Anti-DDoS Premium).
Cross-Team Collaboration & Knowledge Sharing
Engineering excellence thrives on collaboration. You’ll act as a bridge between infrastructure, development, and security teams.
- Partner with developers to refine application architectures using serverless, microservices, and containerization.
- Document standard operating procedures (SOPs) for deployment, recovery, and troubleshooting.
- Lead technical workshops and mentor junior engineers to elevate team capabilities.
