Screaming Penguin - Source Does Matter

That's right. We're hiring for XUL hackers at Yahoo!

Prime candidates will have a wealth of cross-platform C/C++ development experience as well as XUL/Javascript/XPCOM experience. Hopefully, you've already written your own XUL application and used an XPCOM extension as a part of that application. If you've ever submitted a patch to the Mozilla code base that's a huge plus. We fully expect that folks on the team may lean heavily to the DHTML/XUL/Javascript/Python or C++/XPCOM side of the project, but you should have expertise in all areas, particularly as the needs of the development environment may shift.
