In East Asia, there's a role called 'SI' (Systems Integration), but it's rarely recognized as proper career experience. It seems to be different in the West. The reason it's hard to get career recognition is that every company uses different stacks, so you're expected to know a lot of different technologies, but it's hard to go deep in any of them. And the company-specific technologies don't help when you change jobs, so you're effectively treated as bottom-tier. That's what I do for a living too.

In fact, most hardware manufacturers stick with legacy technologies for 'stability' reasons, but that experience is rarely recognized as valuable career capital
