🔴 SENIOR FRONTEND DEVELOPER (DeFi / Protocol-Level UX)
5000-7500 USD

#Frontend #Web3 #DeFi #React #TypeScript #Remote

Company:
A next-generation decentralized trading product built on Chain Abstraction, Account Abstraction, multi-chain infrastructure, and DeFi protocols. The product is already live in production, handling real users and high load, with a clear long-term roadmap (not an experiment).

✦ Job Description:
We’re looking for a Senior Frontend Developer who works not just with UI, but with decentralized logic at the protocol level. This role is for engineers who deeply understand how DeFi products work under the hood and can hide complex Web3 mechanics behind a clear, reliable UX.

Key Responsibilities:
– Develop and evolve the frontend core using React (SPA / PWA / Telegram Mini App).
– Work directly with DeFi protocols and smart contracts.
– Implement complex UX over transactions, calldata, account abstraction, and cross-chain logic.
– Build interfaces for DEXs, swaps, liquidity, lending, and staking.
– Design UX for risk metrics (slippage, liquidation risk, health factor).
– Handle the full transaction lifecycle: sign → send → pending → success / revert.

✦ Qualifications:
– Proven production experience with DeFi protocols (DEXs, bridges, lending, staking).
– Direct interaction with smart contracts: ABI, calldata, events/logs, multicall.
– Hands-on experience with Account Abstraction (ERC-4337 or equivalents): user ops, batching, gas abstraction, paymasters.
– Strong understanding of chain and cross-chain logic, including failures and pending states.
– Senior-level TypeScript + React experience (5+ years).

✦ Preferred Qualifications:
– Experience building real DeFi dashboards (not just marketing UIs).
– Strong understanding of DeFi risks and how to reflect them in UX.
– Writing custom Web3 hooks instead of only using SDK defaults.
– Experience with high-load interfaces and complex state management.

Tech Stack:
– React + Vite / Next.js
– TypeScript
– wagmi / viem / ethers
– Tailwind + Design System (Radix or similar)
