About Datachain

On September 5, 2024, we announced a project to build a cross-border remittance infrastructure 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 its founding in 2018, Datachain has been conducting R&D on technology and business opportunities with the goal of creating a de facto infrastructure as a "global x deep tech" initiative originating in Japan.

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. However, given the large size of the market, global competition is expected to intensify in the future.

In this climate, we are rapidly expanding our recruitment efforts, primarily for our development team, to pioneer the creation of a "de facto infrastructure" based on "global x deep tech" from Japan.

Why Datachain Can Realize This

We have already begun developing an international remittance platform 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 Japan a world leader in legal development. 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 Rewarding

The Lead Product Security Engineer must launch new systems and ensure the ideal system security to drive major new business projects.

Therefore, a leading role is needed to collaborate with members both inside and outside the team to establish policies for achieving a high level of security.

In terms of implementation, in addition to knowledge of regular web application infrastructure, it is necessary to establish management of many highly secure structures, including financial knowledge and blockchain-specific knowledge.
