We're looking for a frontend developer to help build a cross-chain decentralized exchange (DEX) UI. The ideal person has 3–5+ years of experience with React, Next.js, and TypeScript, and has worked on Web3 apps before. They should be comfortable integrating wallets like MetaMask, WalletConnect, and Coinbase using libraries like Wagmi, RainbowKit, or Web3Modal. Strong knowledge of Ethers.js is key for handling Ethereum and EVM-based chains. Bonus points if they’ve worked with Substrate/Polkadot.js, since the DEX backend is built on that stack. They should understand how wallet connections, signatures, RPCs, and chain switching work, and ideally be able to troubleshoot cross-chain quirks. Experience with decentralized protocols and privacy-focused coins like Monero or Bitcoin is a plus. We want someone who writes clean, maintainable code, is security-conscious (especially around wallet/key handling), and can collaborate with backend and design teams. Experience with Tailwind or similar CSS frameworks is great. It’s a plus if they’ve built or contributed to crypto DEXs, trading UIs, or DeFi dashboards.Reach out and we’ll brief you on the stack, scope, and product vision.
