And I have seen a few companies do that! I would say that this is around 20% of the companies.
The other 80% simply list those jobs as "Remote", so they show up on their job pages under all continents, or at least, under their "outside the US" filters.
Then sometimes it's not mentioned at the top of the job offer, but in the footnotes with the "we hire regardless of disability etc." statements.
All of these things are fine. They're just a far cry from that blog post that the CEO made 10 months into quarantine, talking about how the company will open itself to global remote work.
* EU team (e.g. presales) are not available half the day to answer queries and this creates delays, but also forces people to write good tickets if they want anything done
* Conversely, even senior developer staff get half the day clear of meetings to do deep work or focus on internal meetings / mentoring
* Thankfully this team are mature adults, but I've seen an us and them thing develop between engineering and the rest of the company elsewhere. It's natural when everyone outside engineering is short term incentivised to downplay technical debt and such. If it can happen when everyone is in the same building, I can definitely see how easily it could happen if only engineering are sat together and all the evil product owners are just angry faces on a screen.
