Fullstack - Blockchain Developer

We're looking for a Full Stack Developer (Blockchain ) to design and build secure, scalable, and high-performance decentralised 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 decentralised 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, authorisation, and secure data handling patterns across distributed systems.
- Collaborate with cross-functional teams to design and deliver reliable, user-centric decentralised solutions.
- Manage CI/CD pipelines, testing processes, and deployment workflows across traditional and decentralised 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 optimising 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 decentralised deployments.
- Understanding of modern security principles, authentication schemes (JWT, OAuth, WalletConnect) and data integrity in decentralised systems.
- Comfortable with CI/CD, containerization (Docker/Kubernetes), and API testing frameworks.
- 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.
