> this is spoken from a permaemployee perspective.

I've spent more time as a hiring manager than IC in recent years. "permaemployee" feels unnecessarily demeaning.

You're right that it's used differently for finding candidates, but I still don't engage with the feed.

At most I've posted that I have a job opening as a post (not a job listing). The problem is that it's heavily biased toward people who spend a lot of time on LinkedIn scrolling the feed, which in my experience isn't the most positive signal for people you want to hire to focus on your work. Similar story for hiring people who spend all day posting on any social media: They tend to be distracted by their social media fixation and it's hard to keep them focused on work communications instead of their current online argument.
