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

What You Bring to the Table

  • 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

View company profile

We are the Uniswap Foundation, a non-profit organization established in 2022 with a clear and focused mission: to support the growth, decentralization, and sustainability of the Uniswap Protocol and its vibrant ecosystem. Our journey began as an evolution of the Uniswap Grants Program (UGP), a community-led initiative that demonstrated the immense potential of funding projects to enhance the protocol. After a proposal to create a more formal entity received overwhelming support from the Uniswap community, we were formed to take this work to the next level. Our core belief is in a more open and fair financial system, and we see the Uniswap Protocol as the fundamental infrastructure for digital value transfer on the internet. We are here to serve the expansive community of developers, researchers, governance participants, and users who are collectively building the future of decentralized finance (DeFi).

Our work is structured around three main pillars. First, we focus on Growth and Innovation by providing financial grants and other resources to individuals and teams building new tools, applications, and infrastructure on top of Uniswap. We actively seek out and fund high-impact projects that push the boundaries of what's possible in DeFi. Second, we are dedicated to Stewardship and Governance. We aim to reduce friction in the governance process, making it easier for the community to participate in key decisions and to manage the protocol's treasury effectively. We act as a protocol advocate, ensuring its long-term health and decentralization. Finally, we are committed to fostering a sustainable and resilient ecosystem. This includes funding security audits, supporting educational initiatives, and organizing events like hackathons to bring builders together. We are not just funding projects; we are investing in the people and ideas that will ensure Uniswap remains a core piece of internet infrastructure for years to come.
