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.

Preferred Qualifications

Experience with database replication technologies: CDC (Change Data Capture), logical replication, log-based capture (LogMiner, fn_dblog, pgoutput)
Experience with security vulnerability remediation in production systems
Experience building automated test frameworks or improving test coverage for complex systems
Experience with memory safety tooling (AddressSanitizer, ThreadSanitizer, Helgrind)
Experience operating services at scale (multi-region deployments, large customer fleets)
Experience with release management and deployment pipelines for large fleets

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 load.
In the afternoon, you're working on a security fix, ensuring the remediation doesn't 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.
