【フルリモート/フルフレックス】3D/システム開発エンジニア
職種Position System Engineers / Infrastructure Engineers / Web Engineers / Game Developers
会社概要Company profile They are working on industrial applications of image recognition technology using deep learning, edge AI development using network compression technology, and autonomous agent algorithm development and application to drones, connecting basic technology development to real business. They were also selected for J-Startup and are attracting attention as a Japanese AI venture.

Products include appearance inspection using image recognition, autonomous flying drones, automation (autopilot) of construction machinery, air conditioning optimization, and utilization of brainwave data.

Clients who have implemented the products include KDDI, DAIKIN, HITACHI, HONDA, TOYOTA, and many other industries.
仕事内容Job description Our Construction Solutions Division leverages digital twin technology to boost productivity and ensure safety at construction sites.
We are seeking core members who can do more than just write code based on instructions—individuals who can directly engage with clients to understand their challenges and take the initiative in driving projects forward.


【Job Details】
You will work with your team to solve client challenges, handling everything from requirements definition and implementation to the delivery of value. Depending on your aptitude, preferences, and background, you will be entrusted with a wide range of tasks, such as:
Communication with clients (major construction firms, etc.), requirements definition, and project management
Implementation and development of construction machinery simulators
Algorithm development for 3D software and simulators (mathematical optimization, genetic algorithms, etc.)
Development of proprietary solutions integrating digital twin and AI technologies
We are looking for candidates who have a track record of building systems from the ground up—such as experience with 3D engines (Unreal Engine, Godot, etc.) or designing and constructing web/core business systems—and who possess strong communication skills for interacting with clients.
【Example of Solutions】
BIM/CIM-integrated crane simulator
Enables 3D planning for the placement and transport of construction machinery (such as cranes) by utilizing BIM/CIM data. It supports not only pre-construction planning but also plan adjustments during construction, thereby enhancing efficiency and sophistication in construction operations.

【Development Environment】
・Unity
・Unreal Engine
・Godot
・GitHub
・VS Code
*Environment varies by project.

【Example Clients】
We engage in joint research, development, and solution provision with leading companies in the construction industry, such as Nishimatsu Construction and Obayashi Corporation. 【Company Culture】
・Many employees value logical thinking.
・Employees are willing to share knowledge, even across different departments.
・An environment where you can question and propose ways to ensure processes remain meaningful rather than becoming mere formalities.
・An environment that grants autonomy and incorporates individual preferences into work tasks as much as possible.
・A culture that prioritizes enabling employees to perform at their best.
-Fully remote work options available
-Freedom to choose your own work PC
-Access to tools like GitHub Copilot, etc.

【Annual Holidays】
125 days or more (Full two-day weekend system: Saturdays, Sundays, national holidays, and company-designated days)

【Flex-time System】
The system is actively utilized rather than being a mere formality; with no core hours, employees work during the time slots that suit them best.
The work environment offers flexibility to accommodate personal circumstances, such as family needs.
