This is one path: http://www.mozilla.org/careers

Partial proof: https://github.com/mozilla/repositories https://github.com/mozilla-b2g/repositories

(that's 30 _pages_ of github repos, not including the stuff we do that's not on github: http://mxr.mozilla.org/)

Case in point: Source code for the careers site linked above can be found at https://github.com/mozilla/lumbergh/ (we just recently released a redesign, yay!)
