Mitchell became Motorola's chief engineer for its mobile communication products in 1960.

Mitchell, Motorola's chief of portable communication products and Martin Cooper's[13] boss in 1973, played a key role in advancing the development of handheld mobile telephone equipment. Mitchell successfully pushed Motorola to develop wireless communication products that would be small enough to use anywhere and participated in the design of the cellular phone.[14]
