Careers
Join Solunai
Quietly and reliably transforming how Japan works.
We're looking for people who want to take on this challenge with us.
What We Believe
Our Core Values
Quiet Innovation
Not flashy—reliable. We build technology that truly serves the workplace, not technology for its own sake.
Cultural Bridge
Connecting Japan and the world. We understand not just languages, but different ways of working and thinking.
Long-term Thinking
Building for a decade, not a quarter. We focus on sustainable AI implementation that stands the test of time.
For Students & International Talent
Solunai welcomes international students who want to work in Japan and Japanese students seeking to grow in a global environment.
Our team includes members from diverse backgrounds—Netherlands, Brazil, Japan, and more. We believe that the experience of collaborating across languages and cultures is more valuable than any textbook.
As an intern, you'll participate in actual product development and research projects. Not observation—participation. That's the Solunai internship.
We value curiosity and integrity over experience.
