I assume most HN job posts are from small startups. Even if they are established companies with a sizable head count, it seems weird seeing the same exact job post month after month for a year or two straight.

Perhaps? We're a 9 person backend department inside a 250 person ISP. Not the typical type of team we talk about here on HN. I doubt small startups need a pipeline either, they just hire on demand.
