page not found for example.com/custom-post-name

i have created

1. custom post type: jobs
2. custom taxonomy : jobs_division

I wanted url like Custom permalink structure: /%custom-post-type%/%custom-taxonomy%/%post-name%/

I have registered custom post type using the following code using plugin and i am using the twenty fifteen theme

Every thing works fine except for i.e

example.com/jobs

should show all the posts

but it says page not found

here is the code

add_action( 'init', 'boss_cpt' );

function boss_cpt() {
  $labels = array(
    'name'               = 'Jobs',

    'not_found'          = 'No Jobs found.',
    'not_found_in_trash' = 'No Jobs found in Trash.'
  );

  $args = array(
