Fullstack - Blockchain Developer

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.

Requirements

• B.E.\B.Tech\B.S. Candidates' entries with significant prior experience in the fields above will be considered.
• 3+ years of experience in full-stack development with at least 2 years focused on blockchain-based applications.
• Strong proficiency in backend development using Python or Node.js, including building APIs, integrating smart contracts, and optimizing performance.
• Proficiency in frontend development using React (or similar frameworks like Next.js, Angular, or Vue).
• Solid understanding of blockchain concepts transactions, consensus, gas, tokens, smart contracts, and wallets.
• Experience with Ethereum, Polygon, Solana, or similar ecosystems.
• Hands-on experience with Web3.js, Ethers.js, Viem, Hardhat, Foundry or Truffle frameworks.
• Experience deploying and interacting with smart contracts (Solidity or Vyper).
• Familiarity with IPFS, PInata, The Graph, Chainlink, or other Web3 infrastructure tools.
• Familiarity with token standards (ERC-20, ERC-721, ERC-1155).
• Strong grasp of PostgreSQL/MySQL and exposure to NoSQL databases (MongoDB, Firestore, etc.).
• Experience working with cloud platforms (GCP, AWS, or equivalent) for hybrid decentralized deployments.
• Understanding of modern security principles authentication schemes (JWT, OAuth, WalletConnect) and data integrity in decentralized systems.
• Comfortable with CI/CD, containerization (Docker/Kubernetes), and API testing frameworks.

Nice to Have

• Experience with Rust, Go, or TypeScript for blockchain services.
• Exposure to Layer 2 scaling solutions or cross-chain interoperability frameworks.
• Prior contributions to open-source blockchain projects or Web3 communities.
