Staff / Senior Staff Engineer, Kubernetes

About the role

OKX, a leading crypto exchange and developer of OKX Wallet, is hiring a Staff or Senior Staff Engineer focused on Kubernetes. The role owns the lifecycle of large-scale production Kubernetes clusters and runs multi-cloud operations across Alibaba Cloud and AWS. Applicants with a current right to work in Singapore are prioritised.

Key responsibilities

• Kubernetes cluster lifecycle management: build, scaling, version upgrades, daily operations, fault diagnosis and performance tuning, ensuring 7x24 high availability.
• Multi-cloud operations: operate, govern and optimise Alibaba Cloud and AWS resources (containers, networking, storage, IAM, load balancing, databases, object storage), including configuration changes, cost optimisation and disaster recovery.
• Cloud-native architecture: lead containerization and microservices rollout, optimise Pod scheduling, resource quotas, network policies, image management and log monitoring, and resolve resource fragmentation and network interoperability issues.
• Stability and security: build monitoring, alerting, logging and distributed tracing systems, define runbooks, change processes and incident response plans, and harden container runtimes and cluster security.
• Automation and DevOps: write Shell/Python scripts, integrate Jenkins, GitLab CI and ArgoCD, and apply Infrastructure as Code.
• Incident management: lead incident response, root cause analysis and post-mortems, and continuously improve cluster architecture and monitoring.
• Knowledge sharing: track cloud-native and public cloud trends, document best practices and help the team improve multi-cloud K8s operations.

Required profile

• Bachelor's degree or above in a computer-related field.
• 4+ years of hands-on experience operating production-level Kubernetes clusters, independently resolving complex failures and performance bottlenecks.
• Proficiency in Alibaba Cloud (ACK, ECS, SLB, VPC, RAM, RDS, OSS, CloudMonitor) and AWS (EKS, EC2, S3, VPC, IAM, CloudWatch).
• Linux system administration and familiarity with container runtimes (containerd/Docker), CNI, CSI, Istio/Envoy and multi-cluster management.
• Strong Shell and Python automation, CI/CD (Jenkins, GitLab CI, ArgoCD), IaC (Terraform, Ansible, Helm) and observability (Prometheus, Grafana, ELK/EFK, Jaeger, SkyWalking).
• Preferred: large-scale public cloud experience (100+ nodes), multi-cloud cost optimisation, K8s security hardening (OPA/Gatekeeper, Pod Security Standards, Falco), CKA/CKS certification, and AI/LLM workload scheduling.
