Global Internship Program - Full Stack

_HENNGE is tentatively scheduled to relocate our Tokyo headquarters from Shibuya to Shinjuku in April 2027. Depending on your batch, your internship will take place at either our current Shibuya hub or our brand-new Shinjuku office._

**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.

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

### Program Structure

• **Weeks 1-4:** Full-Stack Application Development Project
• **Week 5:** DevOps & Infrastructure Project

### Internship Details

• On-site program at HENNGE’s headquarters in Tokyo (Mon–Fri, 10:00–19:00 JST)
• Mentorship and technical discussions with engineers based in the same office

• This program is **not remote**. Participants are expected to attend on-site.

### Benefits

• Round-trip airfares from and back to your country of residence
• Pre-arrival support and visa guidance
• Medical insurance* and a phone with mobile data will be provided during your internship in Tokyo, Japan**
• Up to 150,000 JPY of monthly subsidy to cover accommodation, meals, transportation, and networking activities
• Subsidized company events on top of monthly subsidy (Monthly Technical Sessions, Board Game Night, Get-to-know-you Lunches, and many others!) to get to know teams across divisions
• Access to online learning platform during the internship period

_* Medical insurance will only be provided to interns who do not reside in Japan_

_** 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.

### Requirements

• Third-year undergraduate or higher (including Master’s and Doctoral students). Recent graduates are welcome to apply
• Pursuing or holding a degree in Computer Science or a related field. If not, equivalent experience from a tech internship or bootcamp is expected
• Fluency in English (Japanese not required)
• Proficiency in Python, Go, or React/Vue in TypeScript
• Knowledge of Linux / MacOS / Unix-like environments
• Interested in open source or tech community activities
• Interested in pursuing a career in Japan

**At least meet three of the following:**

• Experience in cloud computing platforms, especially AWS
• Experience in full stack web application development
• Knowledge of distributed systems
• Knowledge of DevOps tools and practices (CI/CD, Infrastructure as Code)
• Knowledge of Container technology (e.g. Docker)
