Place a link at top AND bottom of each node
You are placing your link in the links object of the $content array which will generally, unless a template file overrides it, render all it's content in one place.

If the one link you have added visually covers your needs, the other one should be placed within the $content array, with a 'light' #weight property (0 for instance) along with the rest of the array's items (body, fields, etc).

the code could look something like this:

$node-&gt;content['top_link'] = array(
  '#markup' =&gt; '&lt;a href="jobs/apply" class="jobs apply"&gt;'.t('Apply').'&lt;/a&gt;',
  '#weight' =&gt; 0,
   );
