Blockchain Web3 Engineer
Role in brief
Tata Consultancy Services is hiring a Blockchain Web3 Engineer to focus on smart contract engineering and Web3 development. This remote role involves designing, developing, and maintaining smart contracts, building backend components for contract interaction, and managing deployment pipelines. Candidates with a strong background in Solidity and EVM-based chains, or enterprise blockchain platforms, should consider applying.
About the role
This role centers on smart contract engineering and Web3 development. The engineer will be responsible for designing, developing, and maintaining smart contracts, ensuring they meet product and security requirements. This includes building backend components to facilitate contract interaction, such as managing transaction orchestration, signature flows, and gas strategies, as well as integrating Web3 SDKs.
A key aspect of the position involves managing the entire contract deployment lifecycle. This includes setting up deployment pipelines, handling ABI and versioning, planning migrations and upgrade strategies using proxy patterns, and coordinating releases. The engineer will also implement secure patterns for contracts and support testing efforts to ensure robustness and reliability.
Beyond smart contracts, the role extends to node operations and infrastructure. The engineer will deploy, configure, and operate blockchain nodes and their supporting infrastructure, including full nodes, archival nodes, RPC endpoints, and validator nodes. Responsibilities also cover managing node upgrades, handling chain configuration changes, responding to incidents in production networks, and implementing operational tooling for monitoring node health and RPC performance.
The listed salary range for this full-time remote position is between $100,000 and $130,000 annually.
Skills that matter here
- Solidity: This role requires hands-on experience with Solidity for designing, developing, and maintaining smart contracts.
- Hardhat: The engineer will use development tooling like Hardhat for smart contract development and deployment.
- Foundry: Development tooling such as Foundry will be utilized for smart contract development and testing.
- EVM-based chains: Experience with EVM-based chains like Ethereum, Polygon, and Arbitrum is necessary for project work.
- Hyperledger Fabric: Experience with enterprise chains such as Hyperledger Fabric is relevant depending on project assignments.
- Quorum: Experience with enterprise chains like Quorum is applicable for certain projects within this role.
Who this role suits
- A candidate who thrives on building and securing blockchain applications from the ground up, with a focus on smart contract integrity.
- Someone who enjoys managing the full lifecycle of blockchain deployments, from development to operational support and infrastructure maintenance.
- An individual who is detail-oriented in handling transaction orchestration, gas strategies, and secure contract patterns.
- A person with a solid understanding of blockchain fundamentals and practical experience with various development tools and chain types.
