Recruitment Background

We are looking for a Senior Front End Engineer for "commmune", a platform that strongly supports community launches and drives successful customer success.

Customer Success and Community are still underdeveloped domains, and the way in which they are developed varies widely from company to company and end-user to end-user. Therefore, there is no right answer. In addition, we are beginning to expand not only domestically but also internationally, and our business and products are becoming more and more complex.

The key to success in this great challenge is "simple code/architecture" and "user experience" with a focus on the front end. There is a limit to simply relying on AI to provide a simplified UI. However, the current commmune is in urgent need of a solution to this issue, as the code accumulated in the past is hindering simplicity and user experience.

We need engineers who are motivated to contribute to this complex situation and create the best product possible. We believe that tackling this difficult challenge will be a great asset for front-end engineers in the age of AI.

Why don't you tackle challenges with a great deal of discretion and create the best products with our sincere members?

Let's work together to create a product that will lead to an exciting future!



  • Work with team POs to refine specifications to maximize value to users.
  • Actively participate in the development process, including feature development, code review, testing, and release
  • Collaborate with team members to improve the development process
  • Collaborate with other teams to improve the internal/external quality of the product.



1. 10 to 100 phase, but can move with great discretion.

  • This is due to the very strong culture/values of "always pursuing the essence" and the need for constant change. 
  • We will not limit the way you do things as long as you can deliver value to our users/customers/organizations. Whether you are following the career path you started with us or changing careers, we will actively support you as long as it makes sense for both you and the company. 
  • You are expected to face "questions you set yourself," not "tasks given to you. This challenging environment is sure to help you grow significantly. 

2. Honest members who have each other's backs.

  • We have many members who are honest and people oriented. This is not only for developers, but also for EM, PdM, etc. 
  • We have the soil to help each other, share goals, and create something of value. 

3. Contribute to "value creation."

  • Commmune does not have a front-end/back-end boundary. We encourage you to work on value creation in whatever form is necessary for your situation. 
  • However, we will respect your intention and characteristics. Therefore, we will not force you to use both the front-end and back-end. 
  • Depending on your intention and effort, you can become a full stack/full cycle engineer. 

4. There is a soil where people can work with spontaneity.

  • The company as a whole has a strong "results-oriented" culture, and as long as you can properly deal with your team and products, you are free to do what you want afterwards.

  • At least 5 years of experience in web application development
  • At least 1 year experience in TypeScript/Node.js development

Development environment
