Do they exist? Sure, I'm exaggerating a little bit. On my current job hunt I try to pay special attention to safety/alignment-related positions, but it seems that a vast majority of them would require me to relocate to either the Bay Area (or the US in general), or London, and I'm just not very eager to do that.
Fwiw I live in London and have been to the Bay Area and I think that London is better across all 4 dimensions you mentioned.
