  • 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

  • Proficiency in frontend development using React (or similar frameworks like , 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 , , 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
