みなさん、プログラミングスキルを「ファッション業界」で活かしたいと考えたことはありませんか？

ファッションは古くから人々の自己表現の手段として愛されてきましたが、近年テクノロジーとの融合により、全く新しい体験と価値を生み出しています。 それが「ファッションテック（Fashion Tech）」という分野です。

AR/VR技術によるバーチャル試着、AIによるパーソナライズ提案、IoTを活用したスマートクロージング、3Dプリンティングによるカスタムファッションなど、技術革新がファッション業界を大きく変革しています。

この記事では、ファッション×技術の最前線で活躍する「ファッションテックエンジニア」について詳しく解説します。 創造性と技術力を両立させ、人々のライフスタイルを豊かにする仕事に興味がある方は、ぜひ最後までお読みください。

ファッションテックエンジニアとは何か

ファッションテックエンジニア（Fashion Tech Engineer）とは、ファッション業界において先端技術を活用し、新しい体験、プロダクト、サービスを創造するエンジニアです。

従来のITエンジニアが効率性や機能性を重視するのに対し、ファッションテックエンジニアは「美的価値」「個人的体験」「感情的つながり」を重視し、技術と美学を融合させます。
