So what's a typical project like for a R&D engineer?

Newly graduated ME, I'm thinking about what types of jobs I want. I would like to work on electro-mechanical devices. I think making instruments for research labs would be pretty cool. It looks like it consists of:

-Making CAD models and getting them from plastics/machines shops.

-Ordering electronic equipment, figuring out how to use/program them.

-Putting them together to make prototypes of devices, test em out in labs.

-Improve upon designs.
