I've seen decent salaries in the UK advertised, hell I even had an interview for a 2nd line support role, fully remote, for £75k ($100k) - a small pay rise, but far less varied and thus less interesting than what I currently do, so I decided to thank them for the opportunity during the interview and put them in touch with someone I knew.
For an interesting job I could be happy with £75k. In fact in the last 20 minutes I've had contact on linkedin for a pre-sales network architect, which sounds like it could be varied and relatively interesting.
However they only list "competitive" as the salary, which I would assume means £35k ($50k)
