It depends who I'm talking to and where I live. Where I live, engineer is a protected title and requires certification/etc so that takes it out of the race. That leaves the other options. Generally I am a Web Developer to people my age or younger, to people older than me I am usually a Computer Programmer but also sometimes a Developer or Software Developer instead. Realistically, I am a Full Stack Website Developer.
Referring to my job doesn't get any easier even as someone in tech.
Lives ARE on the line. It was faulty software that caused the Boeing 737 Max to crash twice, killing 346 people. Software runs your car, the trains, rockets, literally everything.
