Software Engineer - Blockchain

Blockchain Developer

Solana (Rust + Anchor) and EVM-compatible chains (Ethereum, Polygon, Base, BSC).

smart contract development, cross-chain interoperability, and full-stack dApp development with React and Web3 integrations.

Immediate joiners preferred.

Responsibilities

• Develop and deploy smart contracts on Solana (Rust + Anchor) and EVM-based networks using Solidity
• Build full-stack dApps with React.js/Next.js, Web3.js/Ethers.js, and wallet integrations (MetaMask, Phantom, WalletConnect)
• Implement cross-chain features using LayerZero, Wormhole, or Axelar (bridging, syncing, wrapped tokens)
• Write secure, gas-optimized contracts and perform thorough testing (Mocha, Jest, Anchor test suite, Hardhat, Foundry)
• Integrate backend services with Node.js, GraphQL/REST APIs, PostgreSQL/MongoDB, and Redis (optional)
• Automate deployments using Docker and CI tools (GitHub Actions, GitLab CI)
• Monitor and troubleshoot on-chain activity using tools like Tenderly, Etherscan APIs, and Solana Explorer
• Collaborate with frontend and DevOps teams to ensure great UI/UX and scalable infrastructure
  

Required Skills & Experience

• 3+ years of full-stack development experience.
• 1+ year of hands-on Solana smart contract development (Rust + Anchor).
• Proficiency in Solidity and EVM tools (Hardhat, Foundry, Truffle).
• Strong knowledge of Web3 wallet integration, blockchain architecture, and RPC interactions.
• Experience with DeFi, NFTs, DAOs, and decentralized storage (IPFS, Arweave).
• Familiarity with authentication protocols like JWT, OAuth2, and SIWE (Sign-In With Ethereum/Solana).
• Understanding of smart contract vulnerabilities and Web3 security best practices.
• Experience with zk-rollups (zk-SNARKs, zkSync, StarkNet).
