HENNGE’s Global Paid Engineering Internship in Japan

HENNGE’s Global Internship Program is a 4 to 6 week hands-on training program for students and early-career engineers at HENNGE’s headquarters in Tokyo. This is your chance to work with experienced engineers, receive direct mentorship, and build real software engineering skills in an English-speaking environment. No Japanese language skills required!

The program offers two learning paths: focus on front-end development with React or Vue, or build full-stack applications using Python, Go, or TypeScript. Instead of production work, the program prioritizes your growth through training, mentorship, and AWS cloud experience. While the internship is unpaid, HENNGE provides comprehensive financial support and top performers may receive full-time job offers. You can check out BS, MS, PhD and postdoc positions here

AI Usage Policy

HENNGE wants to help you build strong software engineering fundamentals. While AI tools can be helpful, you should not use them to generate code for your training assignments. Your submitted code must be written by you and show your own understanding.

You may use AI to:

• Clarify technical concepts
• Understand documentation better
• Help with non-coding tasks like command-line options

Throughout the program, you will explain your thinking, trade-offs, and design decisions. You are responsible for the quality of your work.
