I don't think its about best practices, its about good design and communication. Even if we are just talking about PhD students, the majority of them are fresh graduates. They are no different than fresh grads in a company. Those grads work with experienced senior software engineers to guide them and provide design advice (not just best practices). Those engineers are often the ones writing the complex/difficult areas of code.

So should a mechanical engineer PhD be designing and making all their own robot parts? Or should the shop engineer help them? The few mechanical engineer PhD's in robotics I know made a few early prototype test parts themselves with help from the shop engineer, but the shop engineer made and even helped design most of it, especially the final prototype.

The point I'm making is that it does work and its proven to work very well (which is why the major industry labs do it). In my experience its Academia that doesn't like it. Anything which appears to take power/freedom away from scientists and gets in the road of their research is rejected. Though I think the core reason is (as other comments have mentioned), there is no incentive for Academia to make it work. The funny thing is that having a RSE working with them would actually help the scientists in the long run and allow them to focus more on the research because they wouldn't have to do everything themselves.

I would argue these should be included in best practices for software engineering.

This is an interesting example. Every mechanical engineer I know has huge respect for their in-house machine shops. Everyone has a story about some design they submitted for fabrication, only to be told by the machinist that their design was terrible and they should do it another way. Generally machining jobs are very well-defined though, you have to submit CAD documents, tolerances etc.

The shops in universities I've worked in have a strong incentive to help people optimise designs because they're the ones doing the manufacturing, and they know what sort of things will work and what won't. But by and large this is informal. Usually this comes in the form of "have you thought about designing this another way, because this is really difficult/expensive/time-consuming to machine". Maybe this is just a cultural thing for machinists?

The PhD question - if your project is to design a new type of part then you should probably do the design. Should you make it though? It depends if the project is specifically looking at fabrication. Otherwise it's normal to dispatch this to a workshop.

In my opinion, it comes down to what your PhD is training you for or what you're hired to do as a postdoc. If your job is data analysis, then I think you should be writing code, but you should be able to get guidance and support. If you're a field biologist with no coding experience and you want to develop an app to take measurements, then that's a case when contracting it out to an in-house development team makes sense. I'm not saying it can't work, but the make in making it work is important.

If you incentivize RSE's properly then their time will become expensive and we need ways of figuring out how to maximise their impact.
