software:maintainer
Keeps the project working over time.
A software maintainer keeps an existing software project working and reachable as the years pass. This trade triages incoming reports, reviews and merges proposed changes, keeps the build passing, updates dependencies, ships security patches, and cuts fresh releases marked with clear version numbers. Work arrives from the developers who write the code and the testers who report problems; each release then moves on to the packager and the delivery engineer. The maintainer holds a finished codebase steady, current, and ready to install over time.
