I ... earned a lot of technical respect from my teammates, but nobody cares at all about my perspective on architecture, scoping, technology investment, tech debt, etc.
How does that work? All the things you talk about are folded into my concept of "technical respect".
In fact they are not at all related. The engineers on my team bought into the ideas I was bringing as I rolled out implementations that proved the value.
Management however was less interested in increased value and more interested in entrenching their existing status and authority levels even if it meant torpedoing obvious and proved-out value-additive / cost effective engineering projects.
Ah, so it wasn't that nobody cared about your perspective. It's that managers didn't care about your perspective.
A gem I've picked up from my experience in different kinds of tech companies: Never work anywhere where managers are the ultimate decision makers. At engineer-driven companies, managers are enablers.
That really is a good heuristic. Managers at these companies should be asking, “what do we need to be doing?” and “what do you need to get it done?” If instead they are dictating what to do or only telling you what you can’t have, that is big trouble.
