Senior Frontend Infrastructure Engineer

Senior EngineerUniswap Labs builds products that help millions of people access DeFi simply and securely — from the Uniswap Web App and Wallet to crypto infrastructure like the Uniswap Trading API, and Unichain. Uniswap Labs also contributes to the development of the Uniswap Protocol, which has processed over $2.9 trillion in volume across thousands of tokens on Ethereum and 12+ other chains.The Apps Infra team is the horizontal foundation that every product team at Uniswap builds on. We own the data layer, design systems, release and QA automation, UI libraries, and shared frontend services.

We also contribute heavily to AI-powered internal tools and automations that help the engineering org ship faster. We're looking for a senior engineer who goes deep: someone who can drive a large-scale migration one week, build an AI-powered CLI tool the next, and ship a polished UI component the week after that. You'll have strong opinions on tooling, care about developer experience, and treat product quality as the backbone of everything you build.ResponsibilitiesOwn and evolve Uniswap's shared frontend infrastructure — design systems, UI component libraries, data-fetching layers (React Query), and notification systems — across web and mobileContribute to product and design engineering work, keeping the team closely connected to what users experienceBuild and contribute to AI-powered internal tools and automations — changelog builders, cherry-pick automations, CLI tools, and workflows that use LLMs like Claude to accelerate developmentLead large-scale migrations (e.g., Tamagui ?
