Can’t find default single-jobs.php

I am tryng to edit the single-jobs.php template. For single.php I want to show an author’s name, for single jobs I do not.

I found this thread (https://wordpress.org/support/topic/changing-single-job-template/) which says to copy the original single-jobs.php from the plugin, but I can’t find that file. Can anyone tell me where I can find it?
