I updated the Hire New Personnel page recently, so that you can hire new employees using credits and they will have relevant skills depending on your choice. Right now you can choose Command School, Engineering School, Academy of Science, or School of Management, and the new employee will have 0.1 skill in whatever skills match those choices.
Later on, I plan to make this process a bit more complicated, and add a small amount of randomness to the process. I'd love to come up with a way to have the employee creation system be a sort of homage to the old Traveller rules and the character creation in Ultima IV where you had to answer a series of questions to determine what kind of character you started with.
I'm still pondering on how to do this without just ripping off the Traveller system. For now, it is possible to get the employees you need to run the various functions that ships need.
