Cloud Database Architect

Database Architecture & Optimization

• Design, deploy, and optimize cloud databases on Alibaba Cloud (RDS, PolarDB, Redis, MongoDB) and AWS (RDS, Aurora, ElastiCache, DynamoDB, RedShift).

• Select appropriate database types (Relational/NoSQL/NewSQL) and service models (managed services vs. self-built clusters) based on business needs.

Operations & Monitoring

• Implement high availability (HA) and disaster recovery (DR) solutions, including 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 solutions (Prometheus, Grafana).

Performance Tuning & Incident Management

• Diagnose and resolve slow queries, lock conflicts, and resource bottlenecks (CPU/IO/memory) through SQL optimization and index design.

• Quickly troubleshoot and resolve production database incidents such as replication lag, connection pool exhaustion, and storage scaling issues.

Security & Compliance

• Manage database access controls via Alibaba Cloud RAM policies and AWS IAM roles to ensure data security.

• Perform regular upgrades and audit log reviews to maintain compliance with GDPR, MLPS, and other regulatory standards.

Automation & Cost Optimization

• Automate database deployment and operations using Terraform, Ansible, or cloud-native tools (Alibaba Cloud ROS, AWS CloudFormation).

• Optimize cloud costs through auto-scaling, reserved instances, and storage tiering (e.g., AWS S3 Glacier).

Cross-Team Collaboration

• Partner with development teams on database design reviews, SQL code standardization, and DevOps processes (e.g., database change management in CI/CD).

Technical Expertise

• Strong proficiency in database services of at least one major public cloud (Alibaba Cloud or AWS), with working knowledge of the other.

• Deep understanding of mainstream databases (MySQL, PostgreSQL, Redis) and advanced SQL optimization/troubleshooting skills.

• Experience with database migration tools (AWS DMS, Alibaba Cloud DTS) and cross-cloud synchronization solutions.

Professional Experience

• 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.

• Proven track record leading cloud database migrations, DR drills, or hybrid cloud projects (preferred).

Additional Skills

• Strong documentation ability for SOPs and contingency planning.

• Excellent communication skills to coordinate across development, operations, and business teams.

• Relevant certifications such as Alibaba Cloud ACP/ACE (Database) or AWS Certified Database - Specialty are highly desirable.

• Bachelor's degree or higher in Computer Science, Software Engineering, or related fields.
