Pass value in form using the amforms plugin
I presume the title of the entry is the name of the job. So if that's the case, just add a hidden input in the form and add the entry's title to the value.

&lt;input type="hidden" name="fields[jobTitle]" value="{{ entry.title }}"&gt;


Then make sure to create a 'jobTitle' text field in the CMS and attach it to that form.
