I worked for different companies including top companies. There's no such things as "meaningful" work when it comes to a project within a company (the size doesn't matter). A project is project and has a budget, as a deadline, involves expensive resources, several layers of management (at least one layer) looking for status updates, etc. My best advice for you is to look for creativity outside of your work environment. Or, to signup for a PhD. Creativity requires no boundaries and your work environment has tones of boundaries. Does it make sense? Don't waste your time... pick up a job that requires not too much energy, maximize your income if you can, then use your free time to build things that matter to YOU.
