As someone with a small amount of background in software engineering (though it's not my primary job) I can say that they do think about these things and do have very experienced software developers working on these projects, but help is always appreciated!
Speaking to the accuracy of the simulations I do think that's more in the domain scientist's court though, since most of these things use pretty specialized numerical models and physical approximations.
Edit: I'd also like to say that I pretty much agree with everything cwal said.
