I of course assume you mean a developer at Rockstar... The creator of GTA and thus conclude that 'game developer' is the answer to the question?
Also being a ninja by night and developer by day would rank pretty high in the 'being cool' charts. Though I believe 'prestige' would come from things such as creating a product that is then acquired by Google or Facebook.
Then again, what is 'prestige' and why would you want it? The whole question implies that validation from others is the best thing you can achieve. While it is nice to be valued by your peers, why not aim for personal happiness and being a valuable parent, family member, friend, etc?
Just do what you want to do and don't worry if people think you have a 'prestigious' job title at a 'prestigious' company.
Edit: then again I realise that it might make you happy to be able to call yourself 'prestigious' so then the question is perfectly valid.
