Send to company email when/before job expires

I am following this tutorial for how to send an email when a job is published – I however am trying to do the opposite, I would like an email to go out to the job author when the job is about to expire/has expired.

I can navigate and write the code but I am having trouble finding the appropriate action hook. Would this be delete_job_listing since you use publish_job_listing in the tutorial?

Example from tutorial

function listing_published_send_email($post_id) {
   $post = get_post($post_id);
   $author = get_userdata($post->post_author);

   $message = "
      Hi ".$author->display_name.",
      Your listing, ".$post->post_title." has just been approved at ".get_permalink( $post_id ).". Well done!
   ";
   wp_mail($author->user_email, "Your job listing is online", $message);
}
add_action('publish_job_listing', 'listing_published_send_email');
