AWS Database Migration Service (DMS) - Database Engineer AWS Database Migration Service has migrated more than 1.5 million workloads to AWS, helping enterprises move from commercial databases (Oracle, SQL Server, DB2) to open-source Aurora and RDS (PostgreSQL, MySQL). As a DMS Database Engineer, you are the front line for customer success. You diagnose complex replication and migration failures, propose database-specific workarounds, and guide customers through production incidents involving CDC, schema migration, and data validation across heterogeneous database engines. You work at the intersection of deep database internals knowledge and customer-facing problem solving - turning ambiguous production failures into root causes and fixes. What you'll do: Diagnose and resolve complex customer escalations involving heterogeneous database migration and replication (Oracle CDC, SQL Server log reading, PostgreSQL logical decoding, MySQL binlog parsing). Perform root cause analysis on production incidents - analyzing core dumps, task logs, metrics, and database behavior to identify whether issues originate in the source, target, or DMS engine. Design and validate migration strategies for large-scale customer engagements, including data validation approaches, performance tuning, and cutover planning. Develop and maintain database-specific test scenarios for our Scalable Test Platform (STP), improving coverage across migration paths and parameter combinations. Collaborate with SDEs to refine migration and replication engine behavior - translating customer-observed database edge cases into reproducible test cases and code fixes. Contribute to Pre-Migration Assessment (PMA) rules that proactively detect configuration issues before customers begin migrations. Leverage and improve AI-powered diagnostic tools (DMS Oncall Agent, Meshclaw) to accelerate troubleshooting and reduce time-to-resolution. Author runbooks, knowledge base articles, and escalation documentation that enable
