If she is not interested in to further study, she should look for jobs in systems engineering or projects management. Perhaps product management or customer support.
These positions are usually filled by engineers, but they do not use them to perform highly technical engineering tasks (e.g. design of microprocessors as well as Software engineering). They focus on using engineering principles and thinking processes that incorporate technical subject matter. The subject material is able to be taught in the workplace.
Engineers are often convinced that if they do not engage in R&D, they’re not doing engineering. If she is a moderate subject knowledge and moderate communication abilities’ but isn’t in a position to pursue further education I believe that the advice Razvan Guleryuz has said is true and I would not bother to search for the perfect R&D job.
