Our global team brings together diverse perspectives and expertise to solve real-world challenges.
We are now looking for skilled and motivated individuals to help us shape the future of AI-driven productivity and digital transformation.
Responsibilities

• Develop cutting edge agentic RAG pipelines.
• Maintain clean, layered architecture (Controller → Use-Case → Repository) with strict linting and code quality checks.

• Implement structured logging, metrics, and alerts using Pino and Datadog to keep production reliable.
• Collaborate with product, design and fellow engineers to turn ideas into robust services.
The Attractiveness of the Position
Work-life balance
We encourages team members to have other activities and responsibilities in life, the average engineer works 40 hours a week. We have flex time, maternity/paternity leave, etc which is something a lot of our proud new parents really appreciate.
Choose where you work
We are set up for remote work, but you are more than welcome to come to our modern office in Shibuya, Tokyo.
International environment
We have people from all corners of the world working together to build the best products possible.
