■ Specific business content
Today, agile development styles are becoming mainstream regardless of the industry, and there are cases where our customers are also moving away from conventional waterfall type development and promoting their steps to advanced and quick development models
As a full-stack engineer, you will be involved in a wide range of industry / product development projects such as finance, distribution, and telecommunications, from Web service customers who have a fast development cycle.
Therefore, depending on the project, you will be in charge of a wide range of areas including front, back end, and infrastructure while incorporating new technologies such as PWA and serverless.

What We Are Looking For 
The product we’re building has been dubbed The Moon Operating System: it’s the digital space for Mitsui and Moon to collaborate on innovation and incubation projects. We’re an early stage team looking for someone who can own our back end services for this product, and jump in to other areas to lend a hand if needed. The perfect addition will strike a balance of working with designers to experiment and iterate, with shipping solid products to production across multiple platforms. Our medium-term future may include offering this as an enterprise product: any experience in this domain is a big bonus.

We are building for reality: We have 50,000 customers ready to use our product. We need to work quickly, diligently, and scale well. We are creatively driven: We want to bring excellent experiences and design collaboration together with strong engineering.

You will be supported by our technical lead and design team, composed of former Google, Apple, and Brightloom designers and engineers. We’ll be growing this team, and we’d love for you to be a part of this process by shaping our culture, interviewing others, and mentoring new team mates.

* Design and implement data models and storage systems, and evolve them over time.
* Deploy easily consumable APIs that support flexible client side implementation and experimentation across different platforms (mobile + web).
* Implement full-stack instrumentation and metrics, so that we can make data driven product decisions.
* Critically assess needs, propose designs and approaches, and select the right tools for your job.
* Mentor and drive best practices across our stack.

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

You will develop and operate the next-generation mobile ordering service ”SelfU” that allows customers to order using their smartphones at restaurants.

It is necessary to think about what the product should be and to improve it.
We would like you to actively participate in the selection of technology and the architecture for that purpose, as well as what kind of functions the product needs.
