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. We9re 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. We9re 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. You9ll have strong opinions on tooling, care about developer experience, and treat product quality as the backbone of everything you build.

Responsibilities

• Own and evolve Uniswap9s 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 12 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

Requirements

• 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 what9s newly possible
• A desire to keep up with modern best practices in web and mobile development

Nice to Have

• 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 :)
