It's also possible they're working for startups with few employees where they might be one of the only developers there (or the most senior after some turnover).

I've worked for startups early in my career where I was the "Lead" guy primarily because I was the only guy in the company with that job, and was thus forced to do run things.

Thankfully I'd already made and released well over a dozen apps and games I made on my own time for various platforms before then, so it wasn't like I had no idea what I was doing.
