Backend Engineer (Data)

Background
At estie, our mission is to visualize the hidden value of cities through data utilization — unlocking their true potential and enriching the lives of the people who live there.

Commercial real estate such as offices, station buildings, and shopping centers forms the foundation of urban life. Despite Tokyo being the world’s largest commercial real estate market, much of its data remains buried and inaccessible — a little-known barrier to better city development.

What kind of future cities could we build if people around the world recognized Japan’s true value and used data-driven insights to allocate resources more effectively?

We believe such a future would spark economic growth and open the path for Japan’s cities to stand proudly on the global stage.

This vision embodies our purpose: “Unlock the true value of industries.”

We have released estie Market Research, a data analytics platform for urban real estate, and subsequent products that have been well received by many clients. Yet, we are still far from where we aim to be. To realize our vision of “Japanese cities thriving on a global scale,” we need more talent, more expertise, and more partners to join us.

At estie, we will continue to launch products that “unlock the true value of industries” and are seeking teammates who will help lead the creation of products that shape a better future for Japan.
