Fuel - Senior Web3 Software Engineer - deCircle

Fuel is a high-performance blockchain operating system that redefines what's possible on Ethereum. By combining unparalleled throughput with the core principles of decentralization and security, our platform simplifies the development process for builders worldwide.

We are looking for a Senior Web3 Software Engineer to lead the development of high-performance decentralized applications (dapps) in a blockchain-native environment. You will own major product surfaces end-to-end—from frontend interfaces to on-chain integrations—collaborating closely with product, design, backend, and smart contract teams to ship secure, reliable, and intuitive experiences for traders and users.

Responsibilities

Design, build, and maintain modern, responsive frontend applications integrated with blockchain protocols for core DeFi products like exchanges.

Integrate with blockchain infrastructure (e.g., EVM chains, Fuel VM), wallet extensions (MetaMask, Phantom, WalletConnect), and on-chain data sources (e.g., subgraphs, indexers).

Implement secure user flows for transactions, multi-sig approvals, cross-chain bridging, and account abstraction.

Collaborate on API design (REST/GraphQL), RPC optimization, and indexer queries for real-time data.

Establish frontend architecture, design systems, and Web3 best practices (testing with Hardhat/Foundry, gas optimization, reentrancy guards, accessibility).

Review code (including Solidity/Sway), mentor engineers, and drive technical decisions on stack interoperability and scalability.

Translate complex DeFi requirements (e.g., MEV protection, oracle feeds) into intuitive UI/UX for trading interfaces.

Proactively identify technical debt in smart contracts or frontend, propose upgrades (e.g., account abstraction), and shape the product roadmap technically
