Mission

Datachain is a Japanese tech startup that conducts research and development as well as product development in the area known as "interoperability," which connects different blockchains. Now in its sixth year since founding, we are on the verge of launching our service in a production environment, building on the results of our research, development, and proof-of-concept experiments.

As a Software Engineer joining us, you will be expected to develop OSS (Open Source Software) products related to interoperability that Datachain is working on, as well as design and develop backend systems for product development using these products. Specifically, you will be involved in the development of applications known as "cross-chain bridges" that execute transactions (cross-chain transactions) such as token transfers between different blockchains.

As of September 2023, we are focusing on the following OSS:

The cross-chain bridge project, named "TOKI," is planned for global release.

In Japan, we have formed technical partnerships with some of the country's leading corporations, such as Mitsubishi UFJ Trust and Banking Corporation and NTT DATA, and our technology has been highly acclaimed. Moving forward, in addition to commercializing collaborative projects within Japan, we aim to provide services globally and enhance our presence worldwide.
