Job Overview

Datachain is committed to making the world one transparent network, striving to connect different blockchains into a cohesive ecosystem. We anticipate a future where various assets will be digitalized (tokenized) and managed on blockchains, aiming to provide the essential infrastructure in such a world.

Since our founding in 2018, we have focused on R&D aiming for long-term significant value rather than short-term minor achievements. As a result, in the area known as "blockchain interoperability," we are regarded as having the top technology domestically and have received recognition globally, including grant funding.

Currently, we are developing a web application known as a "cross-chain bridge" that facilitates convenient transfers (cross-chain transactions) between different blockchains using our research findings. This application, named "TOKI" after the migratory bird "Toki," is intended for global release from the outset.

About TOKI (Our Development Product)


Recruitment Background

The importance of UI in practical applications is increasing. However, Datachain’s engineering team has traditionally focused on technical validation and pilot experiments, which is why our team currently consists mainly of backend engineers. We are using contractors to advance implementation, but we are looking to recruit someone who can lead the front-end domain in the long term to continuously improve our UI/UX services.

The new hire will be in charge of developing TOKI, using Next.js. Post-hire, we anticipate a catch-up phase for blockchain technology knowledge. More details will be provided during the interview process. We plan to initiate more UI-intensive projects besides TOKI, and the new hire will play a leading role in these future projects.


Why This Role Is Exciting

  • Lead position allowing significant influence over technology choices and development processes.
  • Development targeting the global market from launch.
  • Opportunity to contribute and possibly open-source in an evolving field.
  • Challenge to simplify complex structures of inter-blockchain transactions into user-friendly experiences.
  • Engaging in core economic activities like payments and transfers that demand high security.


Working Environment

  • A community of engineers who enjoy discussing technology.
  • Subsidiary of a listed company, combining stability with the opportunity to take on new challenges.
  • Primarily remote work, with a few in-person interactions yearly.


Required Skills

  • Experience in developing web front-ends for commercial services.
  • Experience with TypeScript and React (including Next.js).
  • Experience leading web front-end development:
    • Technology selection
    • Design of development processes
  • Interest in new services and technologies, including blockchain.


Preferred Skills

  • Experience with blockchain technology or related applications.
  • Experience in backend development, such as API servers.
  • Experience developing products for the global market.
  • Experience with prototyping tools like Figma.


Desired Profile

  • Individuals wanting to leverage their experience in a growing field.
  • Interested in improving development setups and enhancing the long-term value of products.
