When I think that in my industry, good mastership of C++ is, what, 30% of what it takes... Throw in real-time design principles and a few different kernels, several CPU architectures, unavoidable Linux and a one or two build systems (Yocto anyone?). And only then comes the real problem domain, communications protocol stacks or image-processing algos, or what have you.
