hey Petra,

So far I didn't saw our customer build a job platform in Easysocial because we do not have any specific functionality for this job platform.

Yes, currently you can use Hikashop extension integration with Easysocial to achieve this.

1. you have to install Hikashop extension in your site and setup properly with your vendor
2. then download this Hikashop plugin from our app store https://stackideas.com/apps/item/3376-hikashop-plugin
3. install this app from backend > Easysocial > application > install
4. Enabled that app then your site vendor can able to add new product through the Easysocial story panel form.

Hope this will help.
