Fullstack - Blockchain Developer

Job Description

About The Role We?re looking for a Full Stack Developer (Blockchain ) to design and build secure, scalable, and high-performance decentralized applications. You?ll 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. You?ll 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. Location: Ahmedabad/Pune
