We do have UK presence now. :) I don't know how these things worked out with other people before that, but I can speak about myself.

I'm one of the community managers at SE and I work from my home in Canada where Stack Exchange does not (yet?) have an office. My arrangement is basically that I send in an invoice every month like any contractor would and it is up to me to take care of my own taxes and so on.
