About CoW DAO

CoW DAO is on a mission to protect Ethereum users from MEV and optimize trade execution across DeFi. We achieve this through the CoW Protocol, CoW Swap (a leading intent-based DEX aggregator), and the innovative MEV Blocker, which together help secure, aggregate, and route trades for optimal outcomes. We also fund values-aligned projects via the CoW Grants Program. CoW Protocol is consistently ranked among the top DEX aggregators by monthly volume and is the largest intent-based exchange. Our MEV Blocker protects trades from harmful MEV extraction and is integrated across the Ethereum ecosystem. The CoW AMM is the only live AMM designed to protect liquidity providers from LVR (loss-versus-rebalancing). With over 100 open-source repositories on GitHub, we’re transparent, community-driven, and deeply committed to the open-source ethos. Our real-time Dune Analytics dashboard showcases billions in cumulative trading volume and a rapidly growing user base. As we continue to scale, CoW DAO remains at the forefront of DeFi innovation, prioritizing security, efficiency, and decentralization.

About the Position

We are hiring a Smart Contract Engineer to help shape the next iterations of CoW Protocol and extend its real-world use cases. If you enjoy digging deep into problems, are not afraid to throw away code, and like collaborating in public with a strong GitHub history, this role is for you. Build new protocol features by designing and implementing smart contracts and ensuring they integrate cleanly with our off-chain infrastructure. Work on sophisticated DeFi integrations such as flash loan-based flows with top protocols, as well as collaborations with leading wallets and lending markets. Help reshape the next iteration of CoW Protocol, focusing on decentralization, verifiable execution, and pragmatic on-chain order settlement. Support the health of the protocol by investigating suspicious transactions, detecting on-chain misbehavior, and contributing to CoW DAO governance discussions and proposals. Review and advise on integrations from external teams, including grant proposals and support for grantees building on top of CoW Protocol. Collaborate in a remote-first environment through code reviews, async discussions, and a public GitHub-driven development process with strong testing and CI.
