DynamoDB Engineer

Responsibilities

• Multi-Region DynamoDB Migration & DR Setup
• Design and execute the migration of DynamoDB tables from us-east-1 to us-east-2.
• Implement Global Tables for an active-passive disaster recovery configuration, laying the groundwork for active-active migration by late 2027
• Data Modeling & Schema
• Analyze existing table structures, partition keys, sort keys, and access patterns. Optimize data models for multi-region replication to maintain sub-millisecond query performance and minimize cross-region latency
• Infrastructure as Code (IaC) Implementation: Author and maintain production-grade Terraform configurations and AWS CDK (TypeScript) modules for DynamoDB resources, including tables, GSIs, capacity settings, auto-scaling, PITR, and backup vaults across both regions
• Capacity Planning & Auto-Scaling
• Design and implement auto-scaling strategies for tables and Global Secondary Indexes (GSIs). Model capacity requirements for cross-region replication traffic, balancing cost efficiency with strict performance SLAs during normal operations and DR scenarios
• Backup, Recovery & Business Continuity
• Implement and validate Point-in-Time Recovery (PITR), on-demand backups, and cross-region backup strategies.
