Similar to your situation, a good friend of mine was 5 years into his HW(EE) career and was interested in pivoting to SW. I referred him to my company at the time. This was almost 10 years ago. He's now one of the most knowledgeable software architects I know in the current trend of JS stack.

From what you describe of yourself it sounds like you may take a similar path. Perhaps you had a few more years in HW, but I wouldn't say that works against you.
