HENNGE’s Global Internship Program (GIP) is an on-site software engineering training program designed and run by HENNGE, a cloud security company based in Tokyo. The program is created for students and early-career engineers who want to strengthen their front-end engineering skills in a global, English-speaking environment at HENNGE’s headquarters in Tokyo.
This Front-End Pathway focuses on hands-on application development training using TypeScript and modern front-end frameworks (such as React or Vue), with mentorship from HENNGE’s experienced engineers. The program emphasizes self-learning, explanation, and collaboration rather than production work.
Japanese is not required.
