International teaching jobs

Has anyone gone the international school route? I'm a school librarian, which means there are fewer roles, but I could potentially get certified in another subject area (not so sure I want to be a traditional classroom teacher though).

We're in a unique situation, as my husband is an EU citizen. We've been looking at Denmark. He recently got a rejection after going through four interviews, but he's still in the process of applying and interviewing. I thought if I was able to secure a job, it may be easier for him to find one once we're actually living there. I am entitled to work there as his spouse, but I don't know if he has to secure employment first, as I believe the chances of getting a visa through a school there are low.
