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.
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
5+ years of software engineering experience
Deep experience with both React and React Native; comfort working across web and mobile from a single codebase
Strong track record building developer tooling, design systems, or shared infrastructure — with a product sensibility that keeps you connected to what users actually touch
Opinions on frontend architecture, styling systems, data-fetching patterns, and build tooling — and the ability to back them up
Experience owning and delivering large, ambiguous projects end-to-end with minimal direction
Comfort with automation: CI/CD, release engineering, testing frameworks
Eager to push the boundaries of AI-assisted development — not just using the tools, but exploring what's newly possible
A desire to keep up with modern best practices in web and mobile development
Active open source contributions — especially to projects like wagmi, viem, Next.js, React Router, TanStack, or similar frontend/tooling ecosystems
Experience building AI-powered developer tools, CLI tools, or internal automations with LLMs
Experience with Swift/Kotlin or native mobile development
Familiarity with crypto features and concepts — candidates with no crypto experience are still welcome (encouraged!) to apply
Experience at companies that value this kind of infra/platform/DX role (e.g., Shopify, Vercel, Replit, Phantom, Coinbase)
Degree in computer science
Love for unicorns :)
