Software Development Engineer, AWS DMS

AWS Database Migration Service (DMS) has migrated more than 1.5 million database workloads to AWS helping enterprises move from commercial databases (Oracle SQL Server DB2) to open-source Amazon Aurora and RDS (PostgreSQL MySQL). The service is used by customers across the world to migrate their most important data from their on-premises datacenters to Amazon services. Our customers depend on our services reliability and security to handle their business data. More information on AWS DMS is available at an SDE2 on the DMS team you will work directly on the core C/C replication engine that powers heterogeneous database migrations for tens of thousands of customers running large-scale production fleets. Youll focus on the PostgreSQL Oracle and SQL Server endpoints - the highest-volume migration paths driving Aurora and RDS growth. Your work will directly impact migration reliability security compliance and the experience of customers migrating their most critical production databases to AWS.

AWS Database Migration Service (DMS) is a part of AWS Utility Computing (UC) which provides product innovations from foundational services such as Amazons Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2) to consistently released new product innovations that continue to set AWSs services and features apart in the industry. As a member of the UC organization youll support the development and management of Compute Database Storage Internet of Things (Iot) Platform and Productivity Apps services in AWS including support for customers who require specialized security solutions for their cloud services.



Key job responsibilities
Design implement and ship fixes and features in the C/C replication engine for PostgreSQL Oracle and SQL Server source/target endpoints.
Diagnose and resolve complex production issues - task crashes memory corruption CDC failures data validation errors - using core dump analysis memory profilers (AddressSanitizer Valgrind) and systematic debugging.
Develop and expand automated test coverage using the Scalable Test Platform (STP) including combinatorial testing scenarios that exercise millions of parameter combinations across migration paths.
Deliver security fixes within SLA and contribute to security compliance initiatives including vulnerability remediation credential exposure prevention and secure supply chain builds.
Participate in code reviews design discussions and release management for our deployment cadence serving hundreds of thousands of production instances.
Collaborate with Database Engineers to reproduce and fix customer-reported issues translating ambiguous production failures into root causes and verified fixes.
Leverage and contribute to AI-powered engineering tools (Meshclaw autonomous bug-fixing Kiro-based on-call agent) to accelerate defect detection and resolution.
Participate in on-call rotation triaging production incidents and driving them to resolution.

A day in the life
You might start the day investigating a crash signature affecting thousands of customer tasks - analyzing the core dump identifying a use-after-free in a CDC thread shutdown path and writing a fix with a coordinated shutdown mechanism. After code review you write an automated test that reproduces the race condition under concurrent the afternoon youre working on a security fix ensuring the remediation doesnt regress existing customer behavior. You end the day reviewing a CR from a teammate fixing a PostgreSQL logical decoding edge case and updating the crash classifier with a new signature your fix will eliminate.

About the team
Our team is dedicated to supporting new members. We have a broad mix of experience levels and tenures and were building an environment that celebrates knowledge-sharing and mentorship. Our senior members enjoy one-on-one mentoring and thorough but kind code reviews.

The DMS engine team operates across Dublin Poland and the US. Were a team that takes ownership of a complex system and makes it better every release -reducing crashes closing security gaps and making migrations reliable enough that customers dont need our help to succeed. We leverage AI extensively: from autonomous bug-fixing to an on-call agent that cuts troubleshooting time dramatically.
