Assuming you are asking this because of the deep learning/ChatGPT hype, the first question you should ask yourself is, do you really need to? The skills needed for CUDA are completely unrelated to building machine learning models. It's like learning to make a TLS library so you can get a full stack web development job. The skills are completely orthogonal. CUDA belongs to the domain of game developers, graphics people, high performance computing and computer engineers (hardware). From the point of view of machine learning development and research, it's nothing more than an implementation detail.

Make sure you are very clear on what you want. Most HR departments cast a wide net (it's like how every junior role requires "3-5 years of experience" when in reality they don't really care). Similarly when hiring, most companies pray for the unicorn developer who can understand the entire stack from the GPU to the end user product domain when the day to day is mostly in Python.
