It seems pretty common with bigger companies: Google, Apple, Facebook, Amazon, Oracle, Box, Zynga, Electronic Arts, Pinterest, Microsoft, etc.

The tracks and levels are commonly referred to as the "job family architecture" -- don't be afraid to ask a recruiter for this information. Otherwise you'll never really know if you're being properly leveled. (For instance, I believe a Principal SE at Microsoft is roughly equal to a Staff Engineer at Google.)
