Backend - Lead Engineer (Next Generation Financial Systems Business)

Description

About the Datachain initiative

Datachain announced a project to build a global payment solutions infrastructure on 5 September 2024!
Since its inception in 2018, Datachain has been continuing R&D on technology and business opportunities with the aim of creating a ‘De-Facto infrastructure’ as a Global x Deep Tech company from Japan.

We aim to become a Decacorn (a start-up with an enterprise value of more than USD 10 billion), and we are often told that we need to win in Global x Deep Tech to realize this goal.

As a major first step, the announced project will start, but we have a limited amount of time to get off to a flying start with a big advantage in this area, where the world's top companies will be our competitors. 

As the first penguin, we are currently rapidly expanding our recruitment in order to create a ‘De-Facto infrastructure’ as a Global x Deep Tech company from Japan.

Position Mission

You will lead the design, development, and operation of back-end systems for a new business supporting next-generation financial systems. Working with product managers, tech leads from other fields, and front-end and blockchain engineers, you will leverage the full technology stack to promote the creation of a globally deployable financial infrastructure.

You will establish a development system that balances speed and quality, from designing highly available APIs to optimizing infrastructure through managed cloud services, building a CI/CD pipeline, and improving documentation. In this position, you will lead the formulation of the underlying technical policy, development flow, and design principles, and will be responsible for creating an environment in which the team can advance development autonomously and providing decision-making support. You will also be expected to drive consensus building with stakeholders on ambiguous requirements and new domains, and play an active role in integrating them into a structural technical framework.

Specifics

• Design, development, and operation of back-end systems
• Formulating and leading technical policies, development flow, and design principles
• Researching and implementing new technology areas
• Ensuring system scalability, maintainability, and security
• Defining requirements, organizing specifications, and building consensus with stakeholders
• Creating an environment where teams can develop autonomously

What's rewarding and attractive about this position

• Ability to participate as a core member in new business ventures from the launch phase
• Ability to participate in building a global, next-generation financial infrastructure
• Highly influential environment, including technology selection and development structure building
• Ability to work with cutting-edge technologies such as blockchain

Technologies Used

• Frontend - TypeScript, Vite, Biome, ESLint, Vitest, Storybook, MSW, Sentry, etc.
• Backend - TypeScript, Jest, etc. (Technology selection in progress)
• Infrastructure - Various AWS services (CDK, Lambda, Aurora, Kinesis, etc.)

Background of this Position

In next-generation financial systems, the backend and blockchain areas are at the core of the product, playing crucial roles in future scalability, maintainability, security, and integration with other areas. Therefore, these areas require increased expertise within the project team and strengthening of technical decision-making and development structures from a long-term perspective. As a lead engineer, you will support technical decision-making and in-house development from a medium- to long-term perspective.

About Our Challenge

Since its founding in 2018, Datachain has continued R&D into technology and business opportunities with the goal of creating a "de facto infrastructure" as a "Japan-made" "global x deep tech" platform.

In the future, all assets are expected to become digital assets, particularly "real-world assets (RWA)," assets with actual value (e.g., stocks, bonds, derivatives, real estate, etc.).

As the financial system is undergoing major transformation, Datachain aims to leverage the technical capabilities it has cultivated to create the next generation of global financial systems. To this end, we are focusing on hiring personnel, primarily for our product development team.
