include custom fields on category page

So I am using a boilerplate wordpress theme, and I have a few custom fields on a custom post type. I’m drawing a blank while trying to get those custom fields to appear on my categories page.

On the individual post pages I can simply use:

print_custom_field('overrideJobDesc');

However when I try the same trick in my categories.php page I get nothing. Can someone point me in the right direction?

<?php get_header(); ?>

            <h1><?php
                printf( __( 'Category Archives: %s', 'boilerplate' ), '' . single_cat_title( '', false ) . '' );
            ?></h1>
            <?php
                $category_description = category_description();
                if ( ! empty( $category_description ) )
                    echo '' . $category_description . '';

            /* Run the loop for the category page to output the posts.
             * If you want to overload this in a child theme then include a file
             * called loop-category.php and that will be used instead.
             */
            get_template_part( 'loop', 'category' );
            ?>
            <?php print_custom_field('overrideJobDesc'); ?>
