Job summary

EPAM Systems, Inc. seeks a DynamoDB Engineer to lead a multi-region migration and establish disaster recovery for hyperscale NoSQL workloads.

You will design Global Tables, implement IaC with Terraform and AWS CDK, and collaborate with application teams to ensure sub-millisecond performance and robust operations. The role requires hands-on DynamoDB data modeling, global secondary index design, capacity planning, PITR, and proactive monitoring.

Responsibilities

• Design and execute multi-region DynamoDB migrations and DR setup across US regions.
• Model data schemas and access patterns for hyper-scale workloads with cross-region replication.
• Author production-grade Terraform configurations and AWS CDK modules for DynamoDB resources (tables, GSIs, capacity, PITR).
• Plan capacity and auto-scaling for tables and GSIs in cross-region scenarios.
• Implement cross-region backup strategies and validate PITR and recovery procedures.
• Establish CloudWatch alarms for replication lag, throttling, capacity usage, and GSI health; participate in DR drills.

Job description

We are seeking an experienced DynamoDB Engineer to spearhead a critical multi-region migration initiative and establish robust disaster recovery capabilities for our hyperscale NoSQL workloads.In this role, you will design and execute the migration of DynamoDB tables across AWS regions, implement Global Tables for business continuity, and lay the architectural foundation for an active-active configuration. You will work closely with application teams, author production-grade infrastructure as code, and ensure operational excellence through comprehensive monitoring and runbooks.Req.#1087120408ResponsibilitiesMulti-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 2027Data Modeling & Schema Design: 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 latencyInfrastructure 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 regionsCapacity Planning & Auto-Scaling: Design and implement auto-scaling strategies for tables and Global Secondary Indexes (GSIs).
