hey, Jess.
We're moving to the UK in just under two years, and I'm currently in the process of finishing my Ph.D. here in the US. I've been scoping out the UK higher ed world and have a few suggestions for you.
First, as I was told just recently, a doctorate is not a requirement for academic posts in the UK. So you shouldn't have a problem finding teaching jobs similar to the ones you've had in the US. Second, many universities, especially the smaller ones and the former polytechnics, may require you to get a Post-Graduate Certificate in Education (PGCE) as part of your contract. That's the teaching credential that you might want as a university lecturer there. They may wave it though, depending on how much teaching experience you have.
I'm not sure if you've found it yet, but the Times publishes a higher education newspaper called THES (Times Higher Education Supplement) that you can get at
http://www.thes.co.uk. Some parts of it are subscription only, but you can at least look at the jobs and some of the articles. Also, the Guardian publishes an education section at
http://education.guardian.co.uk. They give good information about higher education in general.
Finally, I've been told that the best jobs site is
http://jobs.ac.uk. There seem to be lots of jobs on there, so when you get ready to look, there's the spot. Let me know what you find, as I'm always interested to learn more too!
Cheers,
