Description
• 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.
🎯 Exigences
• 5+ years of professional experience as a software engineer, with 2+ years in a senior/lead capacity building Web3 or blockchain applications. • Deep expertise in modern frontend frameworks (React, Next.js , Vue) with TypeScript/JavaScript, plus Web3 libraries ( ethers.js , viem, wagmi). • Strong experience with complex, data-intensive dapps handling real-time streams (e.g., order books, AMM curves). • Proven blockchain integration skills: Browser wallet connections and signing & on-chain interactions via providers (Alchemy, Infura) and libraries for reads/writes/calls. • Solid grasp of web3 security (private key mgmt, blind signing risks, phishing, sandwich attacks). • Backend experience with node services (e.g., Express, FastAPI), off-chain indexers (The Graph), and event listening. • Proficiency in REST/GraphQL, data fetching (SWR, TanStack Query), and state management (Zustand, Redux) in volatile crypto contexts. • Excellent collaboration in fast-paced, autonomous teams using GitHub, Linear, and Discord/Slack. • Nice to have Experience at a CEX/DEX (e.g., Uniswap, Fuel's O2, KuCoin integrations). • Building trading UIs (order books, candlestick charts via TradingView/Lightweight Charts, positions, PnL calculators). • Performance tuning for high-throughput DeFi (sub-ms latency, WebSockets for orderflow). • Prior DeFi/fintech work with tokenomics, liquidity mining, or audited protocols. • Design systems (e.g., RainbowKit, Wagmi connectors) and tooling (Vite, esbuild, Foundry for E2E tests).
