Is there a way that you could add functionality for it to run a page cache purge (?action=purge) after saving a translation? I ran into issues on a private wiki where the list of available languages for a page wouldn't update when adding a new language until the page cache was purged.

This should work correctly out of the box. Is your job queue configured correctly?
Jobs run and the queue is currently empty when I try and run runJobs.php. Is there something special that needs to be setup for Translate?
@Nikerabbit: I see nothing in RenderTranslationPageJob.php that would invalidate the parser cache for other languages when rendering a translation. If the code is not there, where is it?
There is a purge call in \MediaWiki\Extension\Translate\PageTranslation\Hooks::updateTranslationPage
