So just like this ?

$query_args = apply_filters( 'get_job_listings_query_args', $query_args, $args );
    $args = array(
        'orderby'  => 'meta_value',
        'meta_key' => 'rating',
        'meta_query' => array(
            array(
                'key'     => 'rating',
                'value'   => null,
                'compare' => '!='
            )

        ), // End of meta_query
        'fields'  => 'ID',
        'exclude' => array(
            1
        ),

    );

the rating – is already a customer field. So somehow it would be to sort by that custom field – but I have had time figure out how to add this in e.g functions.php
