Yes, you can post jobs on behalf of different companies. In the "Add Job" form, go to the "Employer" section and select "Other employer."
If you choose an unclaimed profile, you’ll first need to claim the profile before you can edit its details from your account.
If you post a job under a profile already claimed by another account, the job will still appear under that employer’s name and on their profile, but you won’t have permission to edit the profile from your account.
