I need help finding an intership.

Hey I was wondering if anyone can help me know what skills do I need to learn if I need to make my career in Machine Learning. I'll tell you my current situation. I know the theory part of ML. I have written a research paper on Semi Supervised Learning with a professor in my college.(I am writing another one). So academically my professor is urging me to continue doing research somewhere for another 3 years of my bachelor's degree and then apply to any company after my PhD. but I don't think I want to. So I am seeing this AI developer roles on LinkedIn but they are looking for developers with a basic knowledge of ML and AI. Where should I apply and for what roles?
