If you already know programming, you can learn the basics of ML in a month. TensorFlow, Keras, PyTorch, etc, makes it super simple to build deep networks and you don't need any advanced math. That's where I would start. Also see the Stanford ML courses: http://cs231n.stanford.edu/

I think I am able to develop end-to-end ML projects. However, my question was about building a career in this space, how to move from junior to senior, from senior to being an expert in the field.
