Kalff ultimately graduated with an engineering degree in 1923. While still a student, Kalff began designing posters and flags, and worked as a designer of theater sets. In 1925 Kalff wrote a letter to Anton Philips, the president of Philips & Co., a company based in Eindhoven that had established itself as a major producer of light bulbs and radio tubes. Kalff told Philips that he felt the company's advertising could be improved. Philips hired him within days as the company's Art Director.
