What level should I target for a career change?

Hello all, I've been learning a lot from the Blind community. My current role is a data scientist with heavy machine learning model development. I'm thinking about career change from non-tech company to a tech company. I have a PhD degree in a non-tech area, and 2 years academia (postdoc) experience and 2 years industry experience (data scientist). I would like to target for a senior data scientist position, but am afraid that my current work is not related to tech. Should I target for a junior data scientist/machine learning position? What's the chance to get hired for a senior data scientist position in tech?
