I call myself a programmer to avoid people thinking I want to be a manager or spend my days in meetings. I want people to expect 90% of my output to be code. If this is good for a career? Don't know don't care. It's what I do and enjoy, and there are many slippery slopes to not coding and becoming rusty, and ending up on the M train by default.
I work on a team of 50 employees. For those 50 people, there are two managers. 1 out of 25 isn’t great odds of being accidentally promoted into management without your consent.
Your working style may be right for you, I’m not questioning that. But in a thread targeted at career advice for junior engineers, I thought it’d chime in from the other side. The chances of accidentally ending up as a manager are very slim. Don’t destroy your career and miss out on interesting opportunities to avoid something that’s not likely in the first place.
