I've worked at Google and Amazon and they would never fire a developer for a buggy release. All engineers write buggy code. With mentorship, code reviews, and reliable test infrastructure, they write fewer bugs. With strong QA and monitoring they ship a lot fewer bugs.

Google and Amazon are not dumb enough to fire an engineer who would cost 10s to 100s of thousands of dollars to replace because that engineer happened to get unlucky and push a release that slipped through all those cracks. (Doing so maliciously would be another story, and would warrant firing.)
