Obviously, this is marketing rather than a serious treatment of the topic. It seems to basically say: "in order to design a system, you should have a regular undergraduate Computer Science education" which seems maybe like a prerequisite (and maybe informative about their hiring process) but not very useful.
However, for what it's worth, the two best resources I've seen for systems design are:
Hints for Computer System Design: http://cseweb.ucsd.edu/classes/wi08/cse221/papers/lampson83....
How to Design a Good API: http://www.youtube.com/watch?v=aAb7hSCtvGw
What else should be in this bibliography?
