This role is for one of Weekdayâs clients
Salary range: Rs 1500000 - Rs 4000000 (ie INR 15-40 LPA)
Min Experience: 3 years
Location: NCR
JobType: full-time
About the Role:
We are looking for a Senior Blockchain Developer to lead the design, development, and deployment of smart contracts and blockchain infrastructure powering our crypto platform. You will work closely with backend, DevOps, and product teams to create secure, scalable, and production-ready decentralized components that interface seamlessly with the rest of our system.
The ideal candidate has hands-on experience with EVM-compatible chains, understands cryptography and consensus, and has built or audited smart contracts in production environments.
Key Responsibilities:
- Design, develop, and deploy smart contracts (primarily Solidity or Vyper) for features such as staking, token issuance, multi-sig, governance, and trading.
- Integrate on-chain contracts with backend systems and off-chain data using oracles and event listeners (e.g., The Graph, Chainlink).
- Optimize gas usage, ensure contract upgradeability, and maintain test coverage with unit/integration tests using frameworks like Hardhat or Foundry.
- Contribute to wallet integrations, token standards (ERC-20, ERC-721, ERC-1155), and bridging mechanisms across chains.
- Review and audit smart contracts internally and externally, identifying security vulnerabilities and business logic issues.
- Collaborate with product, backend, and frontend teams to deliver blockchain features end-to-end.
- Stay up to date with latest L1/L2 developments, EIPs, and tooling to propose and implement improvements.
Required Qualifications:
- 4+ years of software engineering experience, with 2+ years specifically in blockchain development.
- Strong experience with Solidity, and knowledge of EVM internals, gas optimization, and contract design patterns.
- Familiarity with Ethereum and L2 ecosystems (Polygon, Arbitrum, Optimism, zkSync).
- Proficient with blockchain development tools: Hardhat, Foundry, Truffle, Web3.js, Ethers.js.
- Deep understanding of token standards, DeFi protocols, and on-chain governance.
- Experience with multisig wallets, time locks, oracles, and decentralized identity (DID) frameworks.
- Comfortable working with Git, CI/CD, Docker, and collaborative environments.
Preferred Qualifications:
- Experience working on Layer 1 or Layer 2 protocol development.
- Knowledge of Rust or Golang for work on non-EVM chains (e.g., Solana, Polkadot, Cosmos).
- Contributions to open-source blockchain projects or Ethereum Improvement Proposals (EIPs).
- Experience with zk-rollups, zero-knowledge proofs, or verifiable computation.
- Familiarity with compliance protocols (Travel Rule, KYC/AML on-chain solutions).
- Previous work with hardware wallets and MPC-based signing (Fireblocks, Safe, etc.).
What is Truffle Blockchain?
Truffle is a popular development framework for building decentralized applications (dApps) on blockchain platforms, including Ethereum, Binance Smart Chain, and others
The framework provides developers with a suite of tools that make it easier to create, test, and deploy smart contracts and dApps
Truffle also includes a number of integrations with other blockchain development tools and platforms, such as Ganache for local blockchain development and Metamask for Ethereum wallet management
Truffle includes a number of features that simplify the development process, such as:
- Smart contract compilation and migration: Truffle automatically compiles and deploys smart contracts to the blockchain network, making it easier for developers to manage the deployment process.
- Testing framework: Truffle includes a built-in testing framework that enables developers to test their smart contracts and dApps with a variety of testing tools and approaches.
- Debugging and logging: Truffle provides tools for debugging and logging smart contract code, making it easier to diagnose and fix errors and issues during development.
- Built-in libraries: Truffle includes a number of built-in libraries that provide common smart contract functionality, such as OpenZeppelin for token standards and SafeMath for secure arithmetic operations.
