Company mission
To unlock universal ownership and exchange for everyone, starting with bringing millions of people into the emerging web 3.0 economy.
Role
Who you are
- 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
Desirable
- 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 :)
What the job involves
- 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
Our take
Decentralised finance (DeFi) has quickly emerged as a “killer app” for blockchain technology. Within the past two years or so, an ecosystem of hundreds of DeFi applications has developed on Ethereum — with use cases ranging from lending to trading to insurance — bringing permissionless access to financial services to anyone with an internet connection.
Out of these applications, Uniswap - originated by Uniswap Labs - has become the most actively used. It is the largest decentralised exchange (DEX), allowing anyone to create a market for anything, rather than relying on specific teams to be market-makers in an exchange.
Despite the behemoth size of its star asset, Uniswap Labs does not make money from Uniswap, as it is just a protocol with the 0.3% fee going to reward liquidity providers. The company instead relies on adjacent ways to drive revenue, leveraging its massive influence in the DeFi space to do so.
The company has secured impressive funding, including a 2022 Series B round which represented one of the largest raises in the DeFi sector's history. Now boasting a valuation of $1.66 billion, it intends to invest in expanding operations to bring Uniswap to “even more people across the world.”
