I know its a long time since you posted, but i had this issue today and came across your post.
I did some investigating and found it to be a problem with the way wordpress was dealing with the rewrites for canonical redirects.
I did a search on the internet and found the following post on wordpress.stackexchange.com by Celine Garel which deals with this situation for custom post types, i just changed it to work with a page.
Add this to your themes function file,
add_filter( 'redirect_canonical','custom_disable_redirect_canonical' );
function custom_disable_redirect_canonical( $redirect_url ){
if ( is_page('Your_job_list_page') ) $redirect_url = false;
return $redirect_url;
}
This fixed it for me. Hope it helps you or anybody else.
