【About the company】

Development of Small-Scale Decentralized Water Circulation Systems

Development of Autonomous Control Systems for Water Treatment

【 Job Description】

Overview

You'll be responsible for the firmware development that enables autonomous water operation within the company's decentralized water treatment and recycling system products.

You'll be involved in a variety of tasks, including:

・Developing software for various controls on embedded microcontrollers.

・Developing firmware for new sensor devices, either on a real-time OS or as bare-metal.

・Defining requirements, selecting technologies, and designing system architectures related to the above.

・Setting up development environments, including CI/CD and automated testing.

・Investigating bottlenecks and performing performance tuning.

・Developing firmware in C language for controller boards, including interfaces such as UART, I2C, SPI, and 4-20mA.

Japan's water infrastructure, developed with over 100 trillion yen in construction costs since the period of rapid economic growth, boasts world-leading quality and a penetration rate of 98%.

However, this achievement masks a persistent chronic fiscal deficit. This financial strain is set to worsen considerably due to the accelerating population decline and the increasing costs of updating aging facilities—a double burden.

Ensuring the financial sustainability of water infrastructure is an urgent challenge we face to secure a prosperous life with access to water for the next generation.

Development Environment & Tools

・IDEs/Languages: STM32CubeIDE, Python, Git, TypeScript, Linux

・Hardware Tools: ST-Link, Jtag-ice, Oscilloscope, Logic Analyzer, Raspberry Pi

・Cloud/Platforms: AWS IoT, GitHub

Recruitment Background

Since its founding in 2014, the company has been a startup dedicated to creatively solving the "water problem," often called the biggest challenge of the 21st century.

They've been building infrastructure that doesn't rely on traditional water and sewage systems, pushing for its use in disaster areas and regions with limited water resources. Since 2021, they've expanded globally, attracting engineers and researchers from all over the world.

However, their mission to "fundamentally solve water problems by transforming humanity's resource use into a circular society" remains unfulfilled. To achieve the kind of non-linear change needed, they require passionate and ambitious colleagues eager to be first and best in the world.

If you're driven by altruism to help the world and its people, and you feel excited by the highly challenging goal of solving the water problem at its root, then they want to embark on this global challenge with you.

■The Company's Potential

・Global Leadership: The company's products are gaining global attention as revolutionary technology for disaster response and infrastructure development in regions with delayed infrastructure. With high recognition in overseas markets, including participation in COP28 and winning the "most prestigious environmental prize in history," the Earthshot Prize founded by Prince William, it holds the potential to spread a sustainable water circulation model worldwide.

・Socially Significant Technology: Their technology, which streamlines water circulation and reduces wastewater, is a crucial key to overcoming climate change and water resource problems. You can be involved in a highly socially impactful business that supports the creation of a society where people can enjoy "water freedom." In this business growth phase, from Series C onwards and aiming for an IPO, the company is confident there will be many opportunities for you to feel a strong sense of purpose and achievement.

・Organizational Structure Empowering Individual Initiative: Despite being a manufacturing company, it embraces "Hyakunin Keiei" (hundred-person management) as its organizational philosophy. This brings together a diverse group of around 100 talented individuals, allowing the entire organization to evolve through earnest challenges. The company highly values "high purity of talent" to enable "serious play," fosters an "environment that boldly encourages challenges" based on "responsibility and growth," and emphasizes "personnel management that confronts the existential reality of each individual" based on "human love," rather than just uniform evaluation standards.
