Custom taxonomy issues

gistfile1.aw

Currently I have: 
localhost/about/jobs - this works, displays list of job posts
localhost/about/jobs/taxonomy - 404 error (even with taxonomy.php)
localhost/about/jobs/job-post-title - works fine

//Custom post type for jobs
function bment_post_type_jobs() {
	register_post_type(
	    'jobs', array(
	        'labels' => array(
