【This Position is for Japan Residents Only 】


Our team is developing next-generation groupware in domains including IAM, communication, and collaboration in order to achieve our corporate vision of building a society brimming with teamwork.

As part of our product release preparations, we are engaged in the process of iterations identifying customer needs and validating hypotheses based on our findings. To that end, we are looking for a proactive individual who can offer valuable insights with a deep understanding of the product concept and a holistic view of the project.
This position requires the ability to demonstrate thorough proficiency in web technologies, particularly front-end technologies, and the ability to lead efforts in developing architecture design, selecting development tools, and improving development processes.

Our team is multicultural, and we strive to use English as our primary means of communication.
However, some team members are still in the process of acquiring business-level English skills for smoother communication. This means the successful candidate will be sensitive to the communication process and willing to put in additional effort to understand team members’ intentions and ensure they understand yours. Since the engineers are native Japanese speakers, some complicated technical discussions may be conducted in English with supplementary explanation given in Japanese.  
We are looking for an individual who is willing to strive to overcome language barriers in order to collaborate effectively with team members.
