Global Internship Program (GIP) – Full-Stack Pathway
Begin the Application: Click here to register for the coding challenge (no time limit). -------- We're moving! HENNGE is tentatively scheduled to relocate our Tokyo headquarters from Shibuya to Shinjuku in April 2027. All the batches opened for application will take place at our brand-new Shinjuku office. -------- About the Program 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 our Tokyo headquarters.
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.
Internship Schedule Batch 2 (2027): Jun 1 - Jul 16 (7 weeks)
Batch 3 (2027): Aug 2 - Sep 3 (5 weeks)
Batch 4 (2027): Oct 1 - Oct 29 (5 weeks)
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.
Program Structure Monday to Friday, 10:00-19:00 JST
Weeks 1-4: Full-Stack Application Development Project
Week 5: DevOps & Infrastructure Project

** This internship is an unpaid training program with a subsidy provided to all interns
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
Notice for Applicants A limited number of internship slots are available. Applications will be reviewed as they are received, and positions will be filled on a first-come, first-served basis. We encourage you to apply early, as applications will close once all positions are filled .
The coding challenge has no time limit, and the screening process will not consider solving time. Please note that the application is completed after uploading application documents and filling in the batch preferences.
Please take another challenge if you are (also) interested in applying for HENNGE’s GIP Front-end Engineering Pathway. Please use different emails to sign up if you apply for both internships.
