Job summary

Stelo is hiring a Software Development Engineer to work on the engine behind our data replication platform, moving live data between Db2, Oracle, SQL Server, PostgreSQL, MySQL, and cloud platforms. The role emphasizes database knowledge, C++ development, and independence on a small, fully remote team.

Ideal candidates have strong SQL, DB internals, and experience with IBM Db2; we value expertise with CDC, data movement, and integration with cloud platforms.

Qualifications

• Strong SQL and a working understanding of database internals, such as transaction logs, recovery, locking and isolation, query execution, or replication.
• 5+ years building production systems-level or backend software in C++ (databases, storage engines, distributed systems, message brokers, or other high-throughput services).
• Hands-on ODBC or JDBC experience: connection lifecycle, statement execution, parameter and result-set handling, and diagnostics (SQLSTATE, vendor error codes).
• Solid command of multithreading and synchronization in C++, including locks, condition variables, and thread-safe data structures.
• Cross-platform C++ development for Windows (Visual Studio, MSBuild) and Linux (GCC), including debugging and profiling on both.
• Professional use of AI coding assistants, with the judgment to review and test what they produce.
• Clear written and spoken communication, and comfort working on a fully remote, distributed team.
• Bachelor’s degree in computer science, software engineering, or a related field, or equivalent practical experience.

Responsibilities

• Design, build, test, and maintain core components of the replication engine, from capture through apply.
• Integrate with a wide range of sources and targets: Db2, Oracle, SQL Server, PostgreSQL, and MySQL; cloud data platforms such as Snowflake, BigQuery, Databricks, Kafka and Microsoft Fabric.
• Keep replication correct, resilient, and fast across on-premises and cloud environments, and tune data movement across CPU, memory, I/O, and network.
• Work with support, QA, and product to investigate complex customer issues and ship robust, timely fixes and enhancements.
• Help shape design decisions for the platform, including the internal APIs, data structures, and abstractions that simplify cross-database support and configuration.
• Write well-documented, testable code, and review your teammates’ code.
