Role overview
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.
What you'll work on
- Backend Code: Rust, Tokio, Cargo, Git (https://github.com/cowprotocol/services)
- Infrastructure: Pulumi, AWS, Docker, Kubernetes, Grafana, Prometheus, Elasticsearch
- Other codebases: Typescript, Python, Solidity
What we're looking for
- Architect and design our off-chain services (core auction protocol as well as the orderbook) to support feature growth and the rapidly changing requirements that come from being an application on a constantly evolving blockchain.
- While your focus will be writing concurrent backend systems in Rust, you will also interact with our Smart Contracts written in Solidity and develop your understanding of auction mechanisms and DeFi protocols
- Participate in our on-call rotation to help ensure the reliability of our production systems (on-call work is additionally compensated)
- Work closely with researchers and the product team to ship features and come up with new solutions for challenging technical problems
- Deliver high-quality code for features from concept until production (including state-of-the-art monitoring of our production systems)
- Give thoughtful and in-depth code reviews of your colleagues’ contributions to our open-source codebase
