To manually add a new user to your company's profile, you'll want to first go to your Employee Directory. To do this, click on your name in the right hand corner and then select Employee Directory from the drop down menu.
This will take you directly to the Staff Management page. From here, enter the email address of the user you'd like to connect to your company into the box that says "Add existing user by email" and click Add User. This will manually add the user's account to your company's profile on Handshake.
