Hi there. Your post is a little too vague for a really meaningful response. There are lots of science people on this forum, maybe if you specify what field you're in and what your thesis was about generally, then someone might know of an area which pays well. Have you spoken to your supervisor about career options? They should know what's around and what fields you can work in. Have you discussed this with the careers people at your uni? Didn't you have an idea as you were going thru your PhD what areas you might like to work in next? Have you thought about getting a job you like, and not worrying about what it pays, just to start off a post-PhD career?
We'd like to help, but more info pls!
