Jobs in Granada, United States

The Uniswap Foundation is looking for a Protocol Engineer to join our technical team and contribute to the development of smart contracts for in-house projects, the Uniswap Protocol, Unichain, and grantee collaborations.

As a Protocol Engineer, you will play a key role in designing, implementing, and optimizing smart contract systems. You will participate in technical design discussions, weighing trade-offs between optimization, flexibility, and integration, while also providing design feedback for ecosystem participants such as hook developers and Unichain DeFi projects.

What You’ll Do

• Design, implement, and optimize Solidity-based smart contracts for Uniswap-related projects, with a focus on security, efficiency, and maintainability.
• Provide technical guidance and design feedback for external developers building on Uniswap and Unichain, including hook developers and DeFi projects.
• Explore and prototype new DeFi primitives, trading mechanisms, and smart contract architectures to expand Uniswap’s capabilities.
• Participate in design sessions and code reviews, ensuring high standards in code quality, security, and organization.
• Implement unit tests, fuzz testing, and gas optimizations to ensure smart contract reliability and performance.

As a Protocol Engineer, you may work on:

• Hooks and reference implementations for Uniswap v4
• Experimental swapping UX designs
• Indexers and graph traversal algorithms
• Composable DeFi legos
• SDK abstractions and developer tooling
• Periphery integrations such as liquidity management tools and swap-and-add functionalities

• Required Skills & Experience

  • Strong understanding of DeFi patterns and smart contract architecture
  • At least two years of experience writing complex Solidity smart contracts with an emphasis on readability, maintainability, and security
  • Proficiency with Foundry, including cheatcodes, foundry.toml, and script execution
  • Experience with unit testing and fuzz testing for smart contract security
  • Confidence using Git and managing version control in a collaborative engineering environment
  • Ability to design clean abstractions and reusable smart contract components
  • Familiarity with Uniswap v4 contracts and related DeFi protocols

• Nice to haves

  • Experience with Yul and low-level opcodes for gas-efficient smart contract development
  • Knowledge of gas optimization techniques
  • Experience with invariant testing for smart contract correctness
  • Public speaking experience for developer outreach and technical presentations
  • Familiarity with TypeScript for SDK and front-end integrations
