Get custom posts type posts of certain user and display them on his user profile

Hello there,

I use 2 plugins: WP Job Manager (https://wpjobmanager.com/) and Profile Builder Pro (http://www.cozmoslabs.com/wordpress-profile-builder/). With these 2 plugins my registered users can post jobs and have their own user profile.

I want to display the jobs a user submitted with WP Job Manager on his own user profile which is created by the profile builder.

The developer of the job plugin told me the following:

You'll need a custom get_posts() query, and you'll want to get posts by a certain
post_author.

But I have no idea what I have to do now...
Could you help me with that?

Thanks and greetings!
