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 full-stack engineering skills in a global, English-speaking environment at HENNGE’s Shibuya office.
This Full-Stack Pathway focuses on hands-on application development training across back-end, front-end, and basic DevOps, using Python (non-ML stack), Go, or TypeScript on the back-end and TypeScript with modern front-end frameworks on the front-end. The program emphasizes fundamental engineering skills, problem-solving, explanation, and collaboration, rather than production work.
Japanese is not required.

What You’ll Learn & Practice
During the program, you will:
- Develop full-stack web applications as part of structured training projects
- Build and connect back-end APIs and services with front-end applications
- Practice key full-stack engineering concepts, including:
- Back-end logic and API design
- Front-end state management and data flow
- Authentication and security basics
- Software testing (unit, integration, end-to-end)
- Learn, at a practical level, how front-end, back-end, and cloud infrastructure interact
- Work with Unix-like environments and basic DevOps tooling
- Explain your technical decisions, trade-offs, and problem-solving approach during discussions and reviews
- Receive feedback from mentors and iteratively improve your implementation
Our Stance on AI and Software Engineering
AI tools can be helpful, but the goal of HENNGE’s Global Internship Program (GIP) is to help you build strong software engineering fundamentals.
To support that learning, we ask you not to use AI tools to generate code for training assignments or solution implementations. The code you submit should be written by you and reflect your own understanding.
You may use a designated AI service to support your learning in non-code-generating ways, such as clarifying technical concepts, understanding documentation, or helping with non-essential tasks (for example, command-line options).
Throughout the program, you’ll be expected to take ownership of your code and clearly explain your thinking, trade-offs, and design decisions. In this learning environment, you are the engineer and the final gatekeeper of quality.
