As a Staff Engineer for Public Cloud Operations at OKX, you will own the full lifecycle management of enterprise-level hybrid cloud infrastructure. You'll lead unified orchestration, operations, and cost optimization of AWS and Alibaba Cloud resources, ensuring high availability, high performance, and compliance for a leading crypto exchange serving millions of users and hundreds of institutions.

What you'll do

• Plan, deploy, monitor, and maintain AWS services (EC2, S3, VPC, Lambda, EKS) and Alibaba Cloud services (ECS, OSS, VPC, Function Compute, ACK), designing highly available, auto-scaling architectures that optimize network, storage, and compute configurations.
• Implement full-stack monitoring and alerting using cloud-native tools (AWS CloudWatch, Alibaba Cloud CloudMonitor) and open-source solutions (Prometheus+Grafana, ELK), then lead critical incident response, root cause analysis, and implementation of preventive measures.
• Analyze cloud resource usage and reduce costs via reserved instances, auto-scaling, and storage lifecycle policies (e.g., AWS S3 Intelligent-Tiering, Alibaba Cloud OSS Archive), while establishing resource quota management strategies to prevent waste.
• Implement cloud security baselines (security groups, IAM policies, Alibaba Cloud RAM permissions, AWS Security Hub), conduct regular security audits, remediate vulnerabilities, and design granular access controls using AWS IAM and Alibaba Cloud RAM.
• Collaborate with development teams to optimize application architectures and provide cloud-native solutions (Serverless, Microservices), and document operational procedures while leading internal technical training sessions.

What you bring

• Mastery of core services (compute, storage, network, security) on AWS or Alibaba Cloud, with familiarity in the other platform.
• Proficiency in Linux/Windows system operations and automation tools (Shell, Python, Ansible).
• Hands-on experience with containerized operations (Kubernetes, ECS/EKS, ACK) and cloud-native technologies such as Service Mesh.
• 5+ years of operations experience, with at least 3 years focused on public cloud (AWS/Alibaba Cloud) environments managing 100+ instances.
• Excellent team management and communication skills to lead and collaborate with operations, development, testing, and security teams.
• Bachelor's degree or higher in Computer Science, Network Engineering, or a related field.
• Current right to work in Singapore without requiring visa sponsorship.

Nice to have

• Experience building cloud platforms from scratch, hybrid cloud architecture design, or large-scale migration projects (e.g., IDC-to-cloud).
• AWS Certified SysOps Administrator or Alibaba Cloud ACP/ACE certifications.
• Familiarity with multi-cloud management platforms (AWS, Alibaba Cloud, Azure) or FinOps cost optimization methodologies.
• Experience in cloud security practices, including Web Application Firewall (WAF) and DDoS protection (Alibaba Cloud Anti-DDoS Premium, AWS Shield).
• Exposure to big data/AI operations (e.g., Alibaba Cloud MaxCompute, AWS EMR).
