Senior Frontend Infrastructure Engineer
Senior engineer owning shared frontend infrastructure including design systems, UI libraries, data layers, and AI-powered tools across web/mobile at Uniswap. Requires 5+ years experience with React/React Native, developer tooling, and leading large migrations.
About the job
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 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 what's 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
- Experience at companies that value this kind of infra/platform/DX role (e.g., Shopify, Vercel, Replit, Phantom, Coinbase)
- Degree in computer science
Compensation
- Minimum full-time salary of $180,000-$226,000
- Additional compensation elements including tokens, and benefits
