Hi @braehler,
You might be able to use a User Role Editor plugin to assign unique capabilities to a new role you create. The different capabilities that you can add to the role can be found here:
https://github.com/Automattic/WP-Job-Manager/blob/b722b105cd7794f1e9ca2acc58b1212c079acef1/includes/class-wp-job-manager-install.php#L88
Note, however — assistance with implementing customizations is outside of the scope of the support that we offer, per our Support Policy:
https://wpjobmanager.com/support-policy/.
If you need it, you can search for development help in a variety of places — here are a few to start:
https://jobs.wordpress.net/
https://jetpack.pro/
https://codeable.io/?ref=l1TwZ
I’ll leave this open for a few days in case there’s someone else in the community who would like to chime in and lend a hand.
Best of luck.
