About the role
Uniswap 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. When you join Uniswap, you become part of a team that's reshaping the way value flows on the internet. 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're product-centric at our core — the infra we build is always in service of the user experience, and we regularly contribute to product and design engineering work alongside our tooling and platform
responsibilities. 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.
Responsibilities Own and evolve Uniswap's shared frontend infrastructure — design systems, UI component libraries, data-fetching layers (React Query), and notification systems — across web and mobile Contribute to product and design engineering work, keeping
the team closely connected to what users experience Build 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 development Lead large-scale migrations (e.g., Tamagui → Tailwind) with strong opinions on tooling choices and a plan that other teams can follow Build and improve release automation, CI/CD pipelines, and QA tooling to increase reliability and developer velocity Drive performance improvements across the all of our apps Maintain backend-for-frontend services that support multiple product teams Produce high-quality, well-tested code and thoughtful architecture docs; set the bar on PR reviews Mentor engineers across teams through code review, documentation, and establishing best practices where none exist
