To create a job, click on the Jobs menu and then on the "Create a job" button on the right side of your screen:
You can also archive your job positions; this allows you to keep the application history and the candidates found in your searches. To do this, click on the job title and, under the "Status" section, change the status from "Open" or "Paused" to "Archived".
Only archived jobs can then be deleted.
Warning: if you delete a job, you will permanently erase all associated applications.
