Not just software-engineering, either; a lot of large engineering companies don't provide much of an engineering career path that doesn't involve being promoted into management. For almost the entire time my dad was at Amoco (later bought by BP), for a few decades, they were discussing implementing a technical career path with some sort of high-level engineering rank, but it somehow never happened. So the top engineers either languished at "senior engineer" (a reasonably high rank, but basically a ~15 years of experience rank, not equivalent to something like IBM Fellow), or else jumped to management, or left to do consulting. One predictable result was a lot of middle managers who were neither good at nor particularly excited about management, and a lack of senior engineers, in particular engineers in the 3rd phase of a project who had actually worked on the 1st and 2nd phases.
