- Design, deploy, and optimize cloud databases on Alibaba Cloud (RDS, PolarDB, Redis, MongoDB) and AWS (RDS, Aurora, ElastiCache, DynamoDB).
- Select appropriate database types (relational/NoSQL/NewSQL) and service models (managed services vs. self-built clusters) based on business requirements.

- Rapidly resolve production database incidents (e.g., replication lag, connection pool exhaustion, storage scaling).
- Security & Compliance
- Manage database access controls via Alibaba Cloud RAM policies and AWS IAM roles to ensure data security.
- Perform regular database upgrades and audit log analysis to comply with GDPR, Multi-Tier Cloud Security Certification (MLPS), and other regulations.
- Automation & Cost Management
- Automate database deployment and operations using Terraform, Ansible, or cloud-native tools (Alibaba Cloud ROS, AWS CloudFormation).
- Optimize cloud costs via auto-scaling, reserved instances, and storage tiering (e.g., AWS S3 Glacier).
- Cross-Team Collaboration
- Support development teams in database design reviews, SQL code standardization, and DevOps processes (e.g., database change management in CI/CD).
- Team Management
- Manage a team of DBAs to ensure timely completion of projects and efficient resolution of incidents.

- Experience Requirements
- 5+ years of DBA experience, including at least 2 years managing public cloud databases.
- Hands-on experience with large-scale (TB-level) databases, sharding, and read/write splitting.
- Experience leading cloud database migrations, DR drills, or hybrid cloud projects is preferred.
- Soft Skills
- Strong documentation skills for creating SOPs and contingency plans.
- Excellent communication skills to coordinate development, operations, and business teams.
