What We Are Looking For 
We are looking for an exceptional Full Stack Engineer who wants to be part of bringing human-centered innovation into the world. You will have the opportunity to discover and serve unmet user needs by applying your expertise in software development and rapid prototyping to address real-world problems. 

As a Full Stack Engineer, you will help shape our new ventures and drive our innovative work from concept to MVP. You will work with our Venture Designers (Product Managers), across cultures and across portfolios to turn wireframes or similar to tangible digital prototypes or MVPs. 

The problems you will be asked to solve vary by portfolio projects and require discipline across technology stacks and programming languages. 

What You’ll Do at Moon 
Use your software development skills and experience to help implement new digital prototypes and MVPs.
Partner with our Venture Designers and entrepreneurs-in-residence to shape the product vision
Rapidly iterate and develop prototypes to support a project's value proposition
Full-stack development with the right architecture for the project (know when to be scrappy and not to over-engineer)
Collaboratively work with visual and interaction designers

SPA development using Vue.js
Native app development with Flutter

We will entrust you with the development work for the entire front-end area.
The front-end team is responsible for a wide range of in-house Web application and mobile application development.
For example, SelfU is developing a web application for end users, a mobile application for employees (Flutter) for stores, and an application for printing slips in the kitchen (Android native).
We are looking for colleagues who can promote development together with a sense of speed while balancing the quality of the product code and the user experience of both restaurant customers and staff.
