HENNGE K.K.

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 front-end engineering skills in a global, English-speaking environment at HENNGE’s Shibuya office. This 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. Japanese is not required. If you are interested in HENNGE’s GIP: Full-Stack Engineering Pathway instead, please check it out here:https://www.cake.me/companies/hennge/jobs/front-end-engineering-internship What You’ll Learn Practice During the program, you will: Develop front-end applications as part of structured training projects using TypeScript with React or VuePractice key front-end engineering concepts, including:Form validationData fetchingState managementLearn, at a practical level, how front-end applications interact with back-end services and cloud infrastructureExplain your technical decisions, trade-offs, and problem-solving approach during discussions and reviewsReceive feedback from mentors and improve your implementation iteratively 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.

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. If you are interested in HENNGE’s GIP: Front-End Engineering Pathway instead, please check it out here:https://www.cake.me/companies/hennge/jobs/gip-fullstack 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 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.
