Our mechanical engineers are the people who detail out the design, finalize the materials and fabrication processes, prototype it, drop it, kick it, spray it down, and leave it out in the sun in the course of the project.  That’s what your users are going to do.  Our MEs work with the Industrial Designers to carry through the design intent and deliver the desired user interaction.  They also work with the Electrical Engineers to make sure the buttons, LEDs, connectors, and antennas are in the right place so things fit properly.
