Requirements

Mastery of core services (compute/storage/network/security) on AWS or Alibaba Cloud, with familiarity in the other platform.

Proficient 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 (e.g., Service Mesh).

5+ years of operations experience, with at least 3 years focused on public cloud (AWS/Alibaba Cloud) environments managing 100+ instances.

Experience in building cloud platforms from scratch, hybrid cloud architecture design, or large-scale migration projects (e.g., IDC-to-cloud) is preferred.

Strong problem-solving skills with the ability to handle high-pressure operational challenges.

Excellent communication skills to collaborate with development, testing, and security teams.

AWS Certified SysOps Administrator or Alibaba Cloud ACP/ACE certifications are preferred.

Implement full-stack monitoring and alerting using cloud-native tools (AWS CloudWatch, Alibaba Cloud CloudMonitor) and open-source solutions (Prometheus+Grafana, ELK).

Lead critical incident response, perform root cause analysis, and implement preventive measures (e.g., resource contention, misconfigurations, network latency).

Analyse cloud resource usage, reduce costs via reserved instances, auto-scaling, and storage lifecycle policies (e.g., AWS S3 Intelligent-Tiering, Alibaba Cloud OSS Archive).

Establish resource quota management strategies to prevent waste and overspending.

Implement cloud security baselines (security groups, IAM policies, Alibaba Cloud RAM permissions, AWS Security Hub), conduct regular security audits, and remediate vulnerabilities.

Design granular access controls using AWS IAM and Alibaba Cloud RAM, and enforce database auditing (e.g., AWS CloudTrail + Alibaba Cloud DAS).

Collaborate with development teams to optimize application architectures and provide cloud-native solutions (Server-less, Microservices).
