The product engineer works according to 3 complementary, but quite different approaches:
he must of course be able to read and modify a plan on CAD software;
he must also have commercial skills to be able to talk and argue with the client, in order to design a piece that meets a specific specification, while being able to propose areas for improvement or alternatives to the project that was proposed by the instructing party;
and finally, he must be able to imagine products or solutions that address recurring issues, in other words innovate or even file patents.
