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. In return, we commit to mentoring and helping you develop the skills and experiences you seek.

What You’ll Do at Moon 
Use your software development skills and experience to help implement new digital products.

* Deploy reliable, tested, server-side software to testing and production environments in the cloud.
* 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.
