About the Project


We are seeking a skilled and detail-oriented Blockchain Developer to join the Web3 team for "a Stealth Prop-tech startup," a groundbreaking digital real estate platform in Dubai.

  • Build the necessary API endpoints for the frontend applications to interact with blockchain functionalities (e.g., fetching token balances, initiating transactions).
  • Work with backend developers to ensure data consistency between the on-chain state and the platform's off-chain database.
  • Implement event listeners to monitor smart contract events and trigger corresponding actions within the core application.
  • Collaborate with the security team to ensure all integration points are secure and protected against threats.
  • Troubleshoot and resolve issues related to blockchain connectivity and third-party API integrations.

  • 3-5+ years of experience in backend software development, with at least 2+ years focused on integrating systems with blockchain technology.
  • A Bachelor's degree in Computer Science, Engineering, or a related technical field.
  • Strong proficiency in a modern backend language such as Node.js, Python, or Go.
  • Hands-on experience interacting with blockchain networks from a backend service using libraries like Ethers.js, Web3.js, or similar.
  • Proven experience integrating complex third-party REST APIs, particularly for financial or payment systems.
  • A solid understanding of blockchain fundamentals, smart contracts, and wallet interactions.
  • Experience with relational databases (e.g., PostgreSQL) and API design.


Preferred Qualifications


  • Direct experience integrating with specific cryptocurrency payment gateways or asset tokenization platforms.
  • Experience in the PropTech (Property Technology) or FinTech sectors.
  • Familiarity with the regulatory landscape in the UAE, particularly the VARA framework for virtual assets.
  • Experience working in a cloud environment (AWS, Google Cloud, or Azure).
  • Knowledge of message queues (e.g., RabbitMQ, Kafka) for handling blockchain events.
