About the Role :
Were looking for a Full Stack Developer (Blockchain ) to design and build secure, scalable, and high-performance decentralized applications. Youll work across the stack from intuitive frontends to robust backends and integrate seamlessly with blockchain networks and smart contracts. This role requires strong problem-solving ability, hands-on coding skills, and a deep understanding of blockchain fundamentals. Youll collaborate with product, design, and blockchain engineers to turn complex business needs into elegant, production-ready solutions.
Responsibilities :
- Design, develop, and deploy full-stack web applications integrating blockchain functionality.
- Build and integrate smart contracts with backend APIs and frontend interfaces.
- Work with decentralized storage and blockchain interaction layers (e.g., IPFS, Web3, ethers.js, or similar).
- Develop robust, scalable APIs and ensure performance, security, and maintainability.
- Implement authentication, authorization, and secure data handling patterns across distributed systems.
- Collaborate with cross-functional teams to design and deliver reliable, user-centric decentralized solutions.
- Manage CI / CD pipelines, testing processes, and deployment workflows across traditional and decentralized infrastructures.
- Contribute to technical documentation and ensure maintainability and clarity of complex systems.
- Evaluate new blockchain protocols, libraries, and frameworks for potential adoption.
