Seeing a lot more 'open' roles vanish quickly at Jacobs...

I've been keeping an eye on the internal careers portal at Jacobs, more out of habit than anything else. Usually, you see a steady stream of new openings and some older ones linger for a while. Lately though, it seems like roles are either being posted and then disappearing within days, or the "open" status flips to "filled" incredibly fast, sometimes before there's even been a first-round interview advertised. This isn't just for one type of role, either. I'm seeing it across a few different engineering disciplines. It makes me wonder if they're backfilling positions internally due to attrition, or if they're opening roles with the intention of a quick internal move, or worse, if they're using the portal to appear active while quietly restructuring. Anyone else seeing this pattern? It feels like a sign that things might be tightening up, even if there aren't official layoff announcements. Just trying to make sense of the signals before diving into any major career moves. Curious if anyone has a different take or has heard anything specific from HR or leadership.
