No one said it’s made up, just that we don’t know what it is because it’s a term for big (and maybe hardware-oriented) industries. Most devs will never touch this in their lives.

From your link, it seems that the “software architect” is the closest equivalent. He must have a broad knowledge in a bit of everything from the code to talking with clients in order to make good decisions for everyone, and make sure that a good path is followed by everyone.

Last but not least, this book seems interesting and gives an overview of what I said: https://www.amazon.com/Fundamentals-Software-Architecture-Comprehensive-Characteristics/dp/1492043451
