Responsibilities

Database Architecture Design & Optimization

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.

Operations & Monitoring

Implement high availability (HA) and disaster recovery (DR) solutions, such as Alibaba Cloud cross-zone deployments, AWS Multi-AZ, and cross-region replication.

Monitor database performance and health using cloud-native tools (Alibaba Cloud CloudMonitor, AWS CloudWatch) and third-party tools (Prometheus, Grafana).

Performance Tuning & Incident Resolution

Analyze slow queries, lock conflicts, and resource bottlenecks (CPU/IO/memory), optimizing SQL statements and index designs.

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).

Benefits

Competitive total compensation package

L&D programs and Education subsidy for employees' growth and development

Various team building programs and company events

Wellness and meal allowances

Comprehensive healthcare schemes for employees and dependants
