Drupal Jobs is a subsite of Drupal.org.
If you do not already have an account, you will need to create an account on Drupal.org to begin using Drupal Jobs. Note: after providing your username and email address, you will be sent an email message to confirm your email address. You will need to use the one-time login link to set a password and finish completing your Drupal.org profile.
After you have finished creating your account, come back to Drupal Jobs and you will be automatically logged in if you have not logged out of Drupal.org.
