// run function after acf updates fields
add_action('acf/update_post', 20);
function title_from_fields($post_id) {
  // check for your post type
  if (get_post_type($post_id) != 'job_updates')) {
    return;
  }
  // get the post
  $post = get_post($post_id);
  // get the taxonomy field
  $terms = get_field('job', $post_id);
  // taxonomy fields return an array, use the first term
  $term = $terms[0];
  // get date field
  $date = get_field('date', $post_id);
  // set post title/slug
  $title = $term->name.' '.$date;
  $post->post_title = $title;
  $post->post_name = sanitize_title($title);
  // remove this filter to prevent infinite loop
  remove_filter('acf/update_post', 20);
  // update the post
  wp_update_post($post);
  // re-add this filter
  add_action('acf/update_post', 20);
