Maybe you should apply for a Job at Valve so you can employ your awesomeness as a debugger-without-source-code guru. I have to say that the prospect of debugging without source code is probably not on offer and sounds dull. I imagine that most of the debugging is done for you by Steam magic, automatically capturing crashes and problems then uploading data/logs/dumps to Valve so the valve-debuggers-with-source-code-and-Steam-APIs-and-Steam-Documentation gurus can fix and test the problems directly.

Steam awesomeness + debugging awesomeness + Googleing awesomeness == happy camper.
