Carlos Lastres, a Tokyo design engineer who released seven products in four months and was part of the Speechify team that won Apple’s 2025 Apple Design Award for Inclusivity, has published an essay on how Japan created the design engineer title and why the software version of the role is still rare in Tokyo.<\/div>\n

Tokyo, Japan – October 10, 2026 –<\/strong> Carlos Lastres, a Costa Rican AI product designer and design engineer based in Tokyo, has published an essay titled “What a Design Engineer Is in Tokyo, and Why There Are So Few.” It is available in English at lastres.ai\/blog\/design-engineer-tokyo<\/a>, with a Japanese version on the same site.<\/p>\n

The essay defines the role in one sentence: a design engineer is one person who decides what a product should be, designs it, writes the production code, and ships it under their own name.<\/p>\n

A title that started in Tokyo<\/strong><\/p>\n

The essay traces the term to Tokyo. Shunji Yamanaka left Nissan’s design studio, went freelance in 1987, and founded Leading Edge Design in Tokyo in 1994. The Japanese Design Archive Survey credits him with establishing the profession of design engineer: someone who draws an object and also understands the mechanism inside it. His Tagtype keyboard, built with Kinya Tagawa, who later founded Takram, was selected for the permanent collection of MoMA in 2009.<\/p>\n

Lastres argues that the role keeps the same shape today, with software in place of hardware. In an app or a voice assistant, the mechanism is code and the behavior of an AI model, and many of the important design decisions only show up once the product is running.<\/p>\n

Why Tokyo has so few<\/strong><\/p>\n

According to the essay, a search for “design engineer” in Japanese in Tokyo mostly returns mechanical design jobs, and the software version of the role barely exists as a job title in Japanese companies. Lastres gives three reasons:<\/p>\n
