Not necessarily. FAANGs have an army of product/project/program managers, market researchers, and other analysts and experts to handle product vision, etc. for the engineering team. That's the big advantage of being a megacorporation: they can afford the overhead of having their employees be narrowly focused specialists.

(It's also why one sometimes see people who leave FAANGs stumble when they join a startup; they're used to having all that infrastructure supporting them and have to adjust to an environment where it isn't there.)
