After a certain size, one of my favorite Civilization quotes kicks in:
"The bureaucracy is expanding to fill the needs of the expanding bureaucracy."
This burned me right out, and I don't plan on ever working for any Silicon Valley company again. I'm now happily employed in a small (10 person eng team) company where we are all doing meaningful work.
ironically i posted the exact same quote before seeing your post. I've found that whatever work that can be counted as meaningful often also signifies a certain amount of agency that does not exist in a larger bureaucratic system.
Agreed, but the small-company-doing-meaningful-work is also hard to find though.
Startups also often have their own perverse incentives built around the vagaries of venture investments or the whims and personalities of the founders.
