No guarantees, esp. as your site is pretty JS-heavy and as this is not your stock WP-site, but I could try to experiment with some of the following:
* exclude jquery.js
* exclude wp-job-manager
* tick "force JS in head"
* tick "look only in head"
* tick "try/catch javascript"
but a lot will come down to trial & error really. have a look at the FAQ for info on how to do that, in general and keep a look at your browser console for javascript errors that might give away what isn't working.
Have fun!
