About the role

SDE2 on the AWS Database Migration Service (DMS) team developing the core C/C++ replication engine for heterogeneous database migrations (PostgreSQL, Oracle, SQL Server endpoints) to AWS Aurora/RDS. Focus on reliability, security, and large-scale production support across Dublin, Poland, and the US.

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.

Qualifications

  • Experience (non-internship) in professional software development
  • Experience designing or architecting (design patterns, reliability and scaling) of new and existing systems
  • Experience programming with at least one software programming language
