Is there a good website for finding postdocs in Europe?

Something like the equivalent of jobs.ac.uk? I know they have some European jobs but not many.

https://euraxess.ec.europa.eu/ might be of some use. Also is there a European Association for your subject area - mine at least has some postdoc listings on its website. But I don't think there's really a pan-European catch-all site. Perhaps if you posted the countries you're interested in, then people might know the jobs.ac.uk equivalents for those countries?

Thanks Bewildered, I'll check it out. It's the Netherlands I'm specifically looking at and potentially surrounding countries.
