---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 engineering skills in a global, English-speaking environment at HENNGE’s Shibuya office. The program is on-site at our Tokyo headquarters (Mon–Fri, 10:00–19:00 JST).
We currently have two pathways available:
Frontend Pathway:Batch 5 (2026): Nov 16 - Dec 18 (5 weeks)Full-Stack Pathway:Batch 1 (2027): Jan 18 - Feb 19 (5 weeks)Batch 2 (2027): Jun 1 - Jul 16 (7 weeks)
Can't find a time that fits your schedule? We open five batches a year! Sign up for our newsletter to get the latest information here.

The 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.
What You’ll Learn Practice
During the program, you will:
Develop full-stack web applications as part of structured training projectsBuild and connect back-end APIs and services with front-end applicationsPractice key full-stack engineering concepts, including:Back-end logic and API designFront-end state management and data flowAuthentication and security basicsSoftware testing (unit, integration, end-to-end)Learn, at a practical level, how front-end, back-end, and cloud infrastructure interactWork with Unix-like environments and basic DevOps toolingExplain your technical decisions, trade-offs, and problem-solving approach during discussions and reviewsReceive feedback from mentors and iteratively improve your implementation

The 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.
What You’ll Learn Practice
During the program, you will:
