Background
Real estate is deeply connected to nearly every aspect of our daily lives. Whether it's shopping malls, hotels, logistics warehouses powering e-commerce, or data centers supporting the digital world, economic activity always takes place somewhere. At estie, we view real estate as the foundation where economic activity happens, and we're committed to improving people's lives through data and technology.
Commercial real estate—including office buildings, logistics facilities, and shopping centers—is one of the largest asset classes in the world. Tokyo holds the largest stock of institutionally owned commercial real estate globally, making Japan one of the world's most important markets. Despite its scale, much of the industry's information remains fragmented and difficult to access, creating inefficiencies that limit better decision-making and urban development.
At estie, our mission is to transform the commercial real estate industry by making information, operations, and transactions more seamless through technology and data. By unlocking the hidden value of cities, we aim to contribute to the long-term growth of Japan's economy and society.
As we continue to grow, we're investing in the next generation of engineers who will become future technical leaders at estie. We're looking for people with strong learning ability and potential, even if they have limited professional experience in web development.
What You'll Do
As a Junior Web Application Engineer, you'll build a strong foundation in web development while learning how to create business value through software.
From your first day, you'll work on real product features with support from experienced engineers. Over time, you'll be expected to grow rapidly, taking on larger technical challenges and contributing to new product development and business problem-solving alongside senior engineers.
What You'll Learn
Responsibilities
Team & Mentorship
Every engineer who joins estie is assigned a mentor, and junior engineers receive especially hands-on support during onboarding.
Your mentor will help you learn development fundamentals, including Git workflows, frontend-backend collaboration, and development best practices. They will also serve as your primary point of contact for questions and help clarify expectations as you grow. Our goal is for new engineers to make their first production deployment within their first one to two weeks.
You'll join a cross-functional team of approximately five members, including web application engineers, product managers, designers, and design engineers. The environment is highly collaborative, with easy access to senior engineers and strong code review practices that support continuous learning.
You'll also have opportunities to seek guidance from the company CTO and Business Unit CTOs.
