Hello, I just took a job as a senior engineer, working on back-end API's and cloud microservices. I've been working in this area for about 3-4 years now. 

Ultimately I want to be an AI Engineer. Am I specializing too much into back end engineering that I won't be able to become an AI engineer without going back to entry level?

I do have many classes in my undergrad and masters in AI, a couple decent personal projects in NLP, and 3 certifications in AI from my previous employer. 

Very curious to hear senior+ sentiment or anyone who made the switch before who has thoughts and advice.
