[...] Jeff or Sanjay (or any of the other folks operating at that level) will spend their time running a proposed API by clients to ensure it meets their needs, or measuring the performance of subsystems so they fully understand their building blocks, or mentally simulating the operation of the system before building it so they rapidly test out alternatives. They don't actually write more code than a junior developer (oftentimes, they write less), but the code they do write gives them more information, which makes them ensure that they write the right code.
