• Ensure software components are thoroughly tested, documented, communicated, packaged, and successfully delivered.

Requirements

• Strong professional experience as a software engineer, with the ability to independently own complex technical initiatives from development through delivery.
• Strong knowledge of relational databases and SQL.
• Good working knowledge of Python and Java, with experience in additional languages such as Rust, C++, Go, Swift, or Zig considered an advantage.
• Understanding of technical standards, protocols, and APIs, particularly technologies such as HTTP, PostgreSQL Wire Protocol, Python DB API, and JDBC.

• Strong communication skills and the ability to collaborate effectively with engineers, product managers, open source contributors, and external technical partners.
• A genuine interest in open source software and collaborative development practices.
• Existing open source contributions are a plus, but are not required.
