A job posting is easily editable. Login to your account and find the job you'd like to edit. Click the carrot button to the right of the job. You will then see an option to "Edit Details."
Your hired team will be notified that a change has been made to the job. It’s also helpful to update them by posting an announcement to the hired team.
