Backend Engineer (Data)

Background
At estie, we strive to visualize the hidden value of cities through data utilization, aiming to bring out their true potential and enrich the lives of the people who live in them.

In Tokyo—despite being the world’s largest commercial real estate market—vast amounts of data remain buried and underutilized, creating obstacles to better city-building. Few people are aware that this invisibility of data hinders progress.

What if people around the world recognized Japan’s true value and utilized resources based on data? What kind of future city could we build?

A future where the economy thrives and the city competes on a global scale is the future we envision through our purpose: "Unlocking the true value of industries."

We have released "estie Market Research," an urban data analysis platform. While subsequent products have also been well-received, we are still far from our ultimate goal. To realize a future where Japanese cities stand shoulder-to-shoulder with the world’s best, we need more team members and greater capabilities.

At estie, we will continue to launch products that "unlock the true value of industries," and we are looking for team members to lead the development of products that will enhance Japan’s future.
