Job Description

What to expect

We are product focused, meaning you will work on our payment gateway and any other pilot projects towards building the future of KOMOJU. You will work with other engineers in a flat and inclusive culture where engineers have a say in both key product and technology decisions. The culture is largely self-organizing, which means engineers have both a stake and ownership in what they work on. Engineers play to their strengths, but are also able to invest in areas where they want to grow within the team. At KOMOJU, you are the main driver behind your growth and position in the company.

International at our core

Our founder is Canadian, and about 50% of our employees are non-Japanese. In the engineering team, we use English as our common language, and throughout the company, many people are bilingual.

Being an international company we know the importance of bilingualism. We offer all employees a choice between English and Japanese lessons.

About the position

We are looking for a backend engineer to help up build our platform to handle payments on a global scale. You will primarily work with Ruby, building out features using Ruby on Rails. As we’re still scaling our front-end team, you may be asked occasionally to work on front-end tasks as well.

As an engineer you will work collaboratively with the team, to define features and architectures, and then implement them in code. You will also provide constructive feedback through code reviews, as well as architecture discussions.

Our ideal candidate has experience working with large web applications. They will know how to build reliable, scalable, and performant web applications. Testing and code quality are also extremely important to us, so having a strong knowledge of testing and the different testing types is required.

  • Handle refactoring with both bravery and care
