About Datachain

On September 5, 2024, we announced a project to build a cross-border remittance infrastructure in collaboration with international organizations! By using stablecoins, digital currencies whose value is linked to fiat currency, we aim to enable fast, cheap, and convenient international remittances.

Since our founding in 2018, Datachain has been conducting R&D into technology and business opportunities with the goal of creating a de facto infrastructure as a Japanese-made global x deep tech company.

Our company aims to become a decacorn (a startup with a corporate value of over $10 billion), and it's often said that to achieve this goal, we need to "win in global x deep tech."

The aforementioned cross-border remittance infrastructure project was launched as a major first step toward this goal. Currently, we are moving forward with the project with an advantage thanks to Japan's advanced legal framework, but given the size of the market, global competition is expected to intensify in the future.

In this environment, we are currently rapidly expanding our recruitment efforts, primarily for our development team, in order to take the lead in creating a "de facto infrastructure" that is "global x deep tech" originating from Japan.

Why Datachain Can Realize This

We have already begun developing an international remittance infrastructure using stablecoins in collaboration with international organizations that connect financial institutions around the world.

In June 2023, Japan became the first developed country to enact a bill regarding blockchain stablecoins, making it a global leader in terms of legal framework. This is important for major companies to utilize stablecoins.

Datachain's research and development of inter-blockchain communication technology is world-leading.

What Makes This Position So Rewarding

To drive major new business, backend lead engineers need to launch new systems and create the ideal environment for building them.

To create this environment, a team leader is needed.

Understanding the challenges and excitement of establishing a new team, you will take the lead in creating development processes, culture, and systems that allow engineers to work at maximum efficiency.

In terms of implementation, in addition to standard web applications, we will also implement blockchain applications, and each individual will contribute to creating the organization, culture, and systems necessary to achieve continuous development!
