My take would be, if you do go to work for a big company, work for a big company that is in the business of making software. As an implementor you probably give a shit about process, but no company that isn't in the business of making software is going to be run by such people. At best, it will be run by people who pay lip service to process to shut you up, while disguising long-disproved methodology with catchy buzzwords and other bullshit. Somewhere above you in the chain of command you need to have someone with the desire and ability to Do Things The Right Way and the political capital within the organization to make sure it happens. Otherwise you're at the mercy of people who don't give a shit about software development (why should they?). As a software developer, that's not a position you ever want to be in. Of course, even in big software companies this often happens. But at least you'll have a chance.
