You do not need a job first to apply for PhD. If you intend to become a professor in US, the best thing to do is to apply for PhD right after your Bachelors and start purusing your goal. After PhD, you can apply for jobs at Universities in US. Usually, PhD programs are fully funded with scholarship and stipend to cover expenses. The trick is in having a good quality application from your end with good scores and academics so that school sees value in funding your PhD.
