When you get to Career Mode, bonus operations are locked initially. To unlock each one, you need to get a certain number of Perfect jobs from the ones you already have access to. In the past, you didn't have to worry about money and just used all the tools you wanted to. However, when you enter Career mode, it suddenly matters how many tools you use and how much money you use up. To unlock the first bonus operation, you need 60 Perfect jobs. Depending on how you did during Training, you may or may not have already acquired that number. You can always go back and improve on any job you already completed if you think that you can get a perfect there.
