Borrowing from Wikipedia, “The design engineer usually works with a team of engineers and other designers to develop conceptual and detailed designs that ensure a product actually functions, performs and is fit for its purpose.” And again borrowing from Wikipedia, A test engineer is a professional who determines how to create a process that would best test a particular product. These definitions hold true for EMC.
If you need someone to test a product for EMC, you need an EMC Test Engineer. If you need someone to design test equipment and products to pass EMC requirements, you need an EMC Design Engineer.
