Job Description:

We are looking for a skilled Blockchain Developer with hands-on experience in Solana (Rust + Anchor) and EVM-compatible chains (Ethereum, Polygon, Base, BSC). The ideal candidate should have expertise in smart contract development, cross-chain interoperability, and full-stack dApp development with React and Web3 integrations.

You will work on building secure, scalable, and user-centric decentralized applications with seamless wallet and blockchain 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).

- Solid 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).

- Exposure to other chains like Cosmos, NEAR, or React Native/mobile dApps.

- Contributions to open-source blockchain projects.

- Knowledge of MEV, gas fee estimation, and bridging mechanics across chains.
