Background
Real estate is deeply connected to nearly every aspect of our daily lives. When we shop, we visit commercial facilities. When we travel, we stay in hotels. Online shopping relies on logistics warehouses, and engineers depend on data centers. At estie, we see real estate as the foundation where economic activity takes place, and we are committed to enriching people's lives through the power of data and technology.
Investment properties such as office buildings, logistics facilities, and shopping centers are collectively known as commercial real estate. Tokyo is home to the largest stock of institutionally owned commercial real estate in the world, making Japan one of the most significant markets globally. Despite its size and importance, much of the industry's data remains fragmented and inaccessible, creating barriers to more efficient investment decisions and better urban development.
What kind of future cities could be built if people around the world could recognize Japan's true potential and allocate resources based on reliable data? We believe this could unlock economic growth and help create cities that compete on a global scale.
At estie, we are tackling the challenge of transforming the commercial real estate industry by making information, operations, and transactions more seamless through technology and data. To achieve this vision, we continue to expand our products and business domains while building the technological foundation needed to unlock the hidden value of cities and contribute to Japan's future economic growth.
As our company continues to grow, strong technology leadership becomes increasingly important. We are looking for a leader who can drive business growth through technology, make strategic decisions across business, organization, and engineering, and lead a development organization toward meaningful business outcomes.
About the Role
As a Business Unit CTO, you will serve as the technology leader responsible for driving the growth of a business unit through engineering and technical strategy. This role requires executive-level decision-making across business, organization, and technology, with direct accountability for business outcomes as a member of the leadership team.
To maximize execution speed, estie operates under a business-unit structure. Each business unit functions similarly to an independent startup, bringing together engineers, product leaders, and business professionals under a single organization with substantial autonomy and decision-making authority.
You will have broad ownership over engineering within your business unit, including organization design, technology selection, and budget allocation. Product priorities and development initiatives are determined through close collaboration with business leaders, ensuring that technical and business perspectives are aligned.
Your primary mission is to define and execute the technology strategy for your business unit. While contributions to company-wide initiatives are welcome, your main focus will be helping your business unit achieve growth through technical excellence and strong engineering leadership.
Why This Role Is Unique
This role offers the opportunity to act as the CTO of a startup-sized engineering organization while focusing on delivering meaningful business impact. You'll work alongside experienced leaders, including the company CTO and other Business Unit CTOs, enabling high-quality discussions, collaboration, and mutual support.
As estie continues to launch and grow new business units, you'll have opportunities to help build new organizations, create synergies across multiple business domains, and extend your influence beyond a single product area. The role offers significant autonomy and a broad scope for leadership and growth.
Responsibilities
- Solve business challenges through technology and engineering leadership
- Create and maintain an optimal development environment that balances delivery speed, team growth, and system reliability
- Embody and promote estie's culture within your business unit
- Communicate technical topics and decisions effectively from a business perspective
- Lead project management and people management initiatives as needed
Team Structure
You will collaborate closely with experienced leaders, including the company CTO and other Business Unit CTOs. While Business Unit CTOs have a level of autonomy comparable to startup founders, they are supported by regular discussions and collaboration with fellow technology leaders and executive management. You will have significant ownership without having to make critical decisions in isolation.

About estie
Estie aims to solve the challenges of real estate transaction costs caused by data fragmentation.
Real estate transactions involve numerous companies and stakeholders; currently, each company operates its own independent database. As a result, information updates and sharing within companies are often delayed, leading to time lags and increased communication costs.
Estie’s goal is to simplify the data-sharing process by digitizing analog data and building a unified database. They can enable real-time, bidirectional information sharing, thus streamlining the flow of information.
