About Project

We are looking for a talented and experienced Node.js Developer (blockchain experience) who thrives in a fast-paced environment and is ready to tackle new challenges. The project involves the development of a system for working with cryptocurrencies that will partially replace the current structure used in the services. The system will be similar to the tools used by cryptocurrency exchanges for accepting and managing balances, but with specific features for distributing outgoing flows. The integration includes connecting to existing services, such as merchant platforms and systems for handling fiat payments.

  • Understanding of consensus algorithms, cryptographic principles, and decentralized applications (dApps)

RESPONSIBILITIES

  • Write efficient, maintainable code
  • Ability to efficiently design and implement separate self-sufficient components
  • Participate in architectural discussions and technical decision-making
  • Identify potential technical risks and develop mitigation strategies
  • Ensure knowledge is effectively shared and maintained within the team
  • Foster a collaborative and innovative development environment
