About this position

You will build and improve infrastructure surrounding KOMOJU by making our platform highly reliable, efficient, and scalable. You will do this by automating all things infrastructure. This position will require a heavy amount of coding, you will be less of a sysadmin and more of a programmer, working on the infrastructure instead of the application code. In a typical day you can expect to do any of the following:

  • Identify and eliminate manual processes in managing and deploying infrastructure
  • Monitor the system for anomalies, and either eliminate them or automate alerts
  • Provide infrastructure context to the development team

Our applications are mainly hosted on AWS and built with Docker to provide a consistent execution environment between development and production, and deploys are done automatically on merging a PR, through Github Actions. To support this the team have created a deploy tool, barcelona, which they actively maintain.

Because our team works mostly in Ruby you will need to be familiar with the language. Prior knowledge is not a requirement for this position, as the company will support you in learning, but your first few weeks will be spent mostly becoming familiar with Ruby.


  • Develop and automate tooling around infrastructure and monitoring
  • Work hand-in-hand with engineers to improve CI/CD workflows
  • Help improve and formalize disaster recovery at KOMOJU by shortening time to restore service in production
  • Help automate against latest vulnerabilities by services up date


  • Experience writing code
  • Past experience developing tooling around cloud-based infrastructure
  • Strong knowledge working with Linux-based systems
  • Strong knowledge around networking and security

Nice to haves

  • Experience of the Ruby programming language
  • Experience working with AWS and CloudFormation
  • Previous experience developing web applications
  • Able to speak Japanese

KOMOJU (by Degica) is the leading cross-border payment gateway for Japan.

We power payments for companies like video game distribution platform Steam and the popular mobile app TikTok.

Today we help thousands of merchants by providing them with the payment infrastructure they need, through developer-friendly API’s to integrations on popular platforms like Shopify and Wix; we help our merchants grow in all markets they are expanding.

When it comes to engineering, we believe in having a flat, inclusive culture and constantly improving by continuing to evaluate ourselves. We also prize individuality and believe that each member brings their own unique value to the team.

Our development processes are always updating as the company grows, and we have an engineering culture that largely organizes itself and each engineer has a lot of ownership in their own projects. This culture allows engineers to showcase their strengths while continuing to grow.

KOMOJU's policies during COVID-19 are as follows:

  • During COVID-19 all of their members are working from home 100% of the time (previously they allowed up to one day a week).
  • Their current plan is to continue their full remote policy even after COVID-19 is no longer a concern.
  • They’re able to accept applications from overseas, but you may need to work abroad until it’s possible to move to Japan.
