Coding standards, library standards (stuff like naming conventions), software development processes, higher level software design concerns (for example, take in account the need for change in the future as part of a software design), design libraries taking in account extrenal concerns (say, how 3rd parties actually work with them) and so on.
It's basically the next level from software design, which in turns is the next level from coding.
The most senior position one can have in the technical career track in programming is Technical Architect.
As far as I can tell, Google doesn't really have any of those (or they're not at all good at their job).
