Senior Frontend Infrastructure Engineer

• 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

Benefits

• Unlimited and encouraged time off
• 100% company-paid medical, dental, & vision for you and your dependents
• 401(k) participation
• Annual $1,500 education stipend
• Up to 16 weeks paid parental leave
• Home office setup stipend for remote employees
• Daily lunches at NY headquarters- Comfort with automation: CI/CD, release engineering, testing frameworks
• A desire to keep up with modern best practices in web and mobile development
• Deep experience with both React and React Native; comfort working across web and mobile from a single codebase
• Experience owning and delivering large, ambiguous projects end-to-end with minimal direction
• 5+ years of software engineering experience
• Eager to push the boundaries of AI-assisted development — not just using the tools, but exploring what’s newly possible
• Opinions on frontend architecture, styling systems, data-fetching patterns, and build tooling — and the ability to back them up
• Strong track record building developer tooling, design systems, or shared infrastructure — with a product sensibility that keeps you connected to what users actually touch
• 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
• Degree in computer science
• Experience at companies that value this kind of infra/platform/DX role (e.g., Shopify, Vercel, Replit, Phantom, Coinbase)
• Love for unicorns :)
