How to prevent a custom post type from using the archive.php template?

If you are wanting to use a specialized archive template for your custom type, you need an additional archive file. This is named in the form of:

archive-[custom post type name].php

Since your code listing has jobs as the type name, the archive file would be named:

archive-jobs.php

This can resemble the standard archive template, or can be tailored as suits the nature of the custom content type.
